The Effect of the Histone Deacetylase Inhibitor Suberoylanilide Hydroxamic Acid and Paclitaxel Treatment on Full-Thickness Wound Healing in Mice

Introduction Neoadjuvant chemotherapy prior to lumpectomy or mastectomy for breast cancer challenges wound healing. Suberoylanilide hydroxamic acid (SAHA), a histone deacetylase inhibitor, has been shown to work synergistically with paclitaxel in vitro and in preclinical studies. In addition, our laboratory has demonstrated that SAHA treatment decreases paclitaxel-associated stem cell toxicity, modulates inflammatory response, and promotes wound healing in injured fibroblast cells. Our goal was to determine if combined SAHA and paclitaxel treatment would improve wound healing in an in vivo full-thickness murine model, without altering antitumor effect. Methods Thirty-two nude athymic mice received intraperitoneal injections of paclitaxel (20 mg/kg), SAHA (25 mg/kg), paclitaxel + SAHA (20 mg/kg + 25 mg/kg), or no treatment for 2 weeks prior to surgery. Under general anesthesia, 8-mm full-thickness dorsal wounds were created in all animals, and a silicone splint was attached to minimize wound contraction. The wounds were measured twice a week with a surgical caliper until healing was complete. To evaluate the in vivo effect of drug treatment, 16 athymic nude mice with MDA-MB-231 xenografts received the treatments described previously, following which tumor volumes were compared between groups. Results Average wound healing time was prolonged in mice treated with paclitaxel (20 ± 1.9 days), and combination SAHA + paclitaxel therapy improved average wound healing time (17.0 ± 1.8 days). In the xenograft model, the antitumor effect of SAHA and paclitaxel (average tumor volume 43.9 ± 34.1 mm3) was greater than paclitaxel alone (105.8 ± 73.8 mm3). Conclusions The addition of SAHA to taxane chemotherapy improves the therapeutic effect on triple-negative breast cancer while decreasing the detrimental effect of paclitaxel on wound healing. This may have substantial implications on improving outcomes in breast reconstruction following chemotherapy.

Reconstruction of Soft Tissue Defects Around the Knee With Pedicled Perforator Flaps

Purpose To study the availability and effects for application of 4 kinds of perforator flaps in repairing skin and soft tissue defects in different positions around the knee joints. Methods The present study included 26 cases (16 males and 10 females) with soft tissue defects with ages from 7 to 82 years who came to our hospital during September 2012 to August 2016. The wound size ranged from 6 × 3 cm to 15 × 12 cm, and the exposed area ranged from 4 × 2 cm to 10 × 8 cm. Patients were treated with different perforator flaps (descending genicular artery perforator flap, sural neurocutaneous flap, lateral superior genicular artery perforator flap, and lateral popliteal artery perforator flap) and were followed up for 6 months. Results All the transplanted flaps survived well without advent events. Exposed bone, ligament, and skin and soft tissue defects healed well. In the early period, flaps were locally bloated. In the later period, the appearance of flaps was good and close to normal, with abrasion-resistant surfaces. All patients were satisfied with the flap appearance and functional recovery. No secondary necrosis, ulcers, deep infection, or nonunion of bone occurred during the follow-up. Conclusions These 4 kinds of perforator flaps are available methods to repair the skin and soft tissue defects around the knee joints. Suitable perforator flaps should be chosen for different locations of wounds. Level of Evidence Therapeutic study, level IV.

Preoperative Implant Size Is Strongly Associated With Alternations of Implant Size During Secondary Breast Augmentation

Background Breast augmentation is one of the most popular cosmetic surgeries performed worldwide. In turn, there has been an increasing number of secondary breast augmentation procedures in recent years. Implant selection at secondary breast augmentation can be a challenge and is affected by a number of factors. The aim of this study was to assess the main factors affecting the decision-making process with regard to implant volume determination prior to implant exchange. Methods Women who underwent elective breast implant exchange between 2012 and 2016 were included in this study. Medical records were used to acquire implant and patient data. The patient's desires, as well as medical considerations, were taken into account during the implant selection process. Results Two hundred forty-five women with an average age of 43 years (range, 21–69 years) were included in the study. The mean time between primary augmentation and implant exchange was 10 ± 5.7 years. Overall, 192 implants (38.9%) were exchanged with larger implants, 84 implants (17%) were exchanged with smaller implants, and 218 implants (44.1%) were exchanged with implants similar to the preoperative size (±25 mL). In patients who received smaller implants, the mean reduction in implant volume was found to be 78.88 mL. Women were more likely to receive a smaller implant during implant exchange if the preoperative implant volume was larger than 367 mL (P = 0.00006). Among patients who received larger implants, no correlation was found between preoperative and postoperative implant size. A positive correlation was found between the implant age and a reduction in implant size (P = 0.036). However, no correlation was found between the patient's age and the decision to reduce or enlarge implant size upon revision. Conclusions Almost half of patients receive similarly sized implants during elective implant exchange. Among those who did decide to change their implant size, more than twice as many patients opted for a larger implant as opposed to a smaller one. Relatively large preoperative implant size and longer time since primary augmentation were associated with the selection of smaller implants during exchange. Further studies should be conducted to reinforce these results.

Long-term Outcomes After Pediatric Free Flap Reconstruction

Introduction Whereas free tissue transfer has evolved to minimize morbidity in adults, less is known about outcomes after free flaps in children. This study sought to assess short- and long-term outcomes after microvascular reconstruction in the pediatric population. Methods Short- and long-term outcomes of free tissue transfer were assessed using chart-review and quality-of-life surveys. The Pediatric Outcomes Data Collection Instrument was used to evaluate overall health, pain, and ability to participate in normal daily and more vigorous activities. Patient or parent responses were compared against normative data. Results Forty-two patients underwent 48 flap reconstructions at a mean age of 8 years. Median follow-up was 14.9 years. Indications included congenital nevi (n = 19, 42%), lymphatic/vascular malformations (n = 8, 19%), and trauma/burns (n = 6, 14%). There were 21 fasciocutaneous (44%), 19 muscle/myocutaneous (40%), 6 fascial/peritoneal (13%), and 2 osteocutaneous flaps (4%). Major flap complications were observed in 4 patients (9%), whereas major donor-site complications occurred in 2% (1 patient). Valid contact information was available for 25 patients; 16 of these completed surveys (64%). Pediatric Outcomes Data Collection Instrument scores for mobility (median, 52), sports/physical functioning (median, 56), happiness (median, 50), and pain/comfort (median, 56) were not significantly different from normative population score of 50. Similarly, median global functioning score was 99 (maximum, 100) and did not differ between flap types. Discussion Free tissue transfer in the pediatric population is reliable and well-tolerated over time. Surgeons should not hesitate to use free flaps when clinically indicated for pediatric patients.

Aesthetic Refinement in the Creation of the Clitoris, Its Preputial Hood, and Labia Minora in Male-to-Female Transsexual Patients

Background In male-to-female genital sex reassignment surgery, the clitoris, its prepuce, and the labia minora remain among the most difficult structures to construct. We describe the authors' clitoroplasty and vulvoplasty technique. Methods All patients who underwent male-to-female sex reassignment surgery at a single center, between June 2012 and June 2016, were prospectively included. The standard pedicled island neurovascular flap of the glans penis was harvested in a letter M fashion with attached preputial skin. The central triangle of the M was used for the neoclitoris formation. Labia minora and the clitoral prepuce were created with both legs of the M and the preputial skin attached to it. Tactile and erogenous sensitivity was evaluated. Results Ninety-seven patients were included (mean age, 32 years; range, 17–54 years). All clitoroplasties and vulvoplasties were completed in the same surgical stage as the vaginoplasty. There were no cases of deep or total flap necrosis. Eight patients developed partial and superficial skin necrosis of the flap; one presented an abscess in labia majora, and another patient had urethral hematoma; both required drainage. None of the complications left any sequelae. At 6 months' follow-up all patients maintained tactile and erogenous sensitivity. Conclusions The proposed technique represents an aesthetic refinement of the previously described pedicled glans penis flap by allowing the creation of a sensate neoclitoris, its preputial hood, and labia minora with excellent outcomes in the same surgical stage as the sex reassignment.

The Evolution of Iliac Bone Graft Donor Site Analgesia in Cleft Patients: Transversus Abdominis Plane Block Is Safe and Efficacious

Background The transversus abdominis plane (TAP) block has been increasingly used as a means of abdominal wall analgesia. This study aims to determine if TAP block analgesia provides a benefit in cleft patients undergoing alveolar bone grafting with iliac crest cancellous bone graft. Methods Two groups of 20 consecutive patients undergoing alveolar bone grafting with iliac crest cancellous bone with either TAP block or indwelling catheter pain pump were examined in a retrospective fashion. Demographic data, pharmacologic use, and hospital length of stay were examined. Results Mean lengths of stay were identical between both groups. Patients in both groups received similar cumulative doses of morphine equivalents, codeine, ibuprofen, and ondansetron at 6 and 24 hours postoperatively. Transversus abdominis plane block patients received greater amounts of Tylenol at both 6 and 24 hours (P = 0.0015 and P = 0.0106). Pain scores did not differ significantly across our groups at 6 or 24 hours postoperatively. No adverse events were reported with the TAP block procedure. Conclusions Patients undergoing TAP blocks receive the benefit of a single stage procedure without an indwelling catheter and similar 6- and 24-hour morphine usage. Given the safety profile of the procedure, its effectiveness and comfort without indwelling catheter, we advocate for TAP block analgesia as an adjunct therapy in the management of postoperative pain in this population.

A Comparative Clinical Study of Flap Thickness: Medial Sural Artery Perforator Flap Versus Anterolateral Thigh Flap

Introduction The purpose of this study is to measure flap thicknesses of anterolateral thigh (ALT) and medial sural artery perforator (MSAP) flaps in healthy subjects by Doppler ultrasonography and compare the results in relation to sex and body mass index (BMI). Method The perforators of ALT and MSAP flaps were marked on 30 healthy subjects. The thickness of skin and subcutaneous tissue was measured in millimeters at the site of the perforator using Doppler ultrasonography. Results The mean ± SD age of the participants was 36.4 ± 10.5, the mean ± SD BMI was 25.2 ± 3.9 (19.4–32.5). The mean ± SD flap thickness was 11.55 ± 4.38 mm for ALT and 8.31 ± 3.6 mm mm for MSAP (P

Discrepancies Between Surgical Oncologists and Plastic Surgeons in Patient Information Provision and Personal Opinions Towards Immediate Breast Reconstruction

Background Immediate breast reconstruction (IBR) may improve quality of life of patients receiving mastectomy. However, a significant hospital variation exists in the use of IBR due to various reasons. To better understand this variation, the present study investigated preoperative information provision to patients and personal opinions of surgical oncologists and plastic surgeons towards potential contra-indications for IBR. Methods An online survey (35 questions) was developed including questions on respondent demographics, information provision to the patient about IBR and potential contra-indications by IBR technique. Results One-hundred-eighty-nine physicians participated: 118 surgical oncologists and 71 plastic surgeons. All clinicians discussed the possibility of IBR with their patients. Complications (79% versus 100%, P 75 years, breast size >D-cup, BMI >40 kg/m2, smoking (for implant reconstruction), pulmonary/cardiac comorbidities (for autologous reconstruction) and radiotherapy were considered a contra-indication more frequently by plastic surgeons. In contrast, surgical oncologists reported tumor stage (≥cT3), nodal stage (≥cN2) and chemotherapy more frequently to be a contra-indication for IBR. Conclusion We observed that all respondents discussed the possibility of IBR with their patients, whereas patient-tailored information was given more frequently by plastic surgeons. Physicians differed in their opinions towards contra-indications for IBR, with plastic surgeons reporting patient-related risk factors for wound healing problems and surgical oncologists reporting oncological contra-indications more frequently. Consensus between physicians regarding contra-indications for IBR may optimize patient counseling and shared decision-making.

Breast Reconstruction May Improve Work Ability and Productivity After Breast Cancer Surgery

Objective The aim of this study was to evaluate work ability and productivity in women who had undergone different types of surgical treatment for breast cancer, as well as breast reconstruction after mastectomy. Methods This cross-sectional study assessed 152 women between 30 and 60 years of age, who worked outside the home in formal or informal jobs, or as self-employed. Thirty-eight of them had no history of breast cancer (control group), and 114 had undergone surgical treatment for breast cancer at least 1 year before their enrollment in the study, and were allocated as follows: mastectomy group (n = 38), breast-conserving surgery group (n = 38), or breast reconstruction breast reconstruction group (n = 38). The validated Brazilian versions of the Work Productivity and Activity Impairment-General Health questionnaire and Work Limitations Questionnaire were self-administered. Results The groups were homogeneous regarding age, education level, and other sociodemographic characteristics. Patients in the mastectomy and breast-conserving surgery groups showed reduced work performance and productivity compared with women in the breast reconstruction and control groups (P = 0.0004 and P = 0.0006, respectively). In addition, women in the mastectomy group had more difficulty in performing activities of daily living compared with those in other groups (P = 0.0121). Conclusions Women who had undergone mastectomy or breast-conserving surgery had decreased work ability and productivity compared with women without a history of breast cancer and to those who had undergone breast reconstruction.

Low-Temperature Burn on Replanted Fingers and Free Flaps in Hand

Background Patients who have undergone microsurgery for reconstruction with a free flap or finger replantation are vulnerable to heat injury. Moreover, some of these injuries can occur at low temperatures. Although the temperature does not reach the threshold to cause burns in the adjacent normal tissues, burns can occur in the areas that underwent microsurgery. On the other hand, this type of burn is not completely understood and there are few reports of the clinical prognosis. Methods The medical records of patients who received warm therapy using an infrared heat lamp with the appropriate temperature after hand surgery from January 2009 to December 2016 were reviewed. The patients were classified into 2 groups. Group A comprised patients who underwent free flap or replantation surgery of the hand. Group B comprised patients who underwent other hand surgeries without microsurgery, such as tenorrhaphy, tenolysis, or joint surgery. Through the medical records, all patients with second- or third-degree thermal burns were selected. The relationship between the 2 types of surgery and thermal injury and the timing of the burn after microsurgery were analyzed. Results Groups A and B were composed of 370 (mean age, 48.2 years) and 7010 patients (mean age, 44.5 years), respectively. Burns requiring treatment occurred in 4 patients in group A and in 1 patient in group B. The proportion of low-temperature burns was 4 of 370 in group A and 1 of 7010 in group B. The occurrence of low-temperature burns was more associated with patients who had undergone microsurgery for a hand reconstruction with free flap or finger replantation (P

Outcome Analysis of Metacarpal and Phalangeal Fixation Techniques at Bellevue Hospital

Purpose Phalangeal fractures represent a significant portion of upper extremity injuries but are not well studied as a single entity. We define our approach at a level 1 trauma center and determine whether plating or lag screws (ie, rigid fixation) have superior functional outcomes compared with Kirschner wire fixation for phalangeal or metacarpal fractures. Methods We performed a systematic review of all surgically managed hand fracture cases at Bellevue Hospital during 2012 and 2013. Demographics, type of fixation, length of operation, period of immobilization, range of motion, time to return to work, and complications including reoperation were noted. Comparisons were assessed for significance using Student t tests and Fisher exact test (P 0.05). Total active motion and return to work were similar regardless of type of intervention in both fracture types. No patients treated with rigid fixation required reoperation. Conclusions To our best knowledge, this is the first review to study phalangeal fractures concurrently but also separately from metacarpal fractures. Despite shorter periods of immobilization, rigid fixation does not appear to lead to improved total active motion or time to return to work.

Medial Plantar Venous Flap: Classic Donor Site Modification for Hand Defects

Background Destruction of digits from trauma results in a much more significant influence on patients' mental state and quality of life than do injuries to other parts. The purpose of this study was to describe a novel modification of medial plantar venous flap for soft tissue defects in the hands and digits. Methods Nine patients received medial plantar venous flap to resurface soft tissue defects in the hands or digits between January 2015 and February 2017. This flap can be used either in a free-island pattern or in a flow-through pattern through the medial branch of the great saphenous vein. All patient data including preoperative statues and follow-up examinations (flap survival rates, complication rates, total active motion, static 2-point discrimination, and Semme-Weinstein test score) were analyzed. Results We included 6 men and 3 women, with a mean age of 34.2 years. The medial plantar venous flaps were used for vascularization in 5 patients because of segmental defects of bilateral digit arteries. Eight flaps survived uneventfully in this study. One flap partially failed (20% of the flap area) because of venous congestion. The functional outcomes and sensory restoration were satisfied for all 9 flaps. Conclusions Compared with the traditional medial plantar flap, the medial plantar venous flap involves a simpler surgical procedure and allows for revascularization of distal areas using the flow-through technique. Furthermore, the medial plantar area presents a sensitive, glabrous skin with proper bulkiness and allows for movement of the underlying structure.

Surgical Resection of Occult Subungual Glomus Tumors: Cold Sensitivity and Sonographic Findings

Purpose We surgically treated subungual masses that were suspected glomus tumors, although definitive clinical and radiological findings were lacking. We report the outcomes of a retrospective case series. Methods Of 42 patients treated by surgical resection between March 1996 and December 2015, 7 who met our inclusion/exclusion criteria were evaluated. At least 1 symptom of the typical triad (temperature sensitivity, severe pain, and localized tenderness) was absent, and computed tomography (CT) and magnetic resonance imaging (MRI) findings were normal. After ultrasonographic evaluation, we resected the masses using a transungual approach or a nail-preserving method. After pathological confirmation of the diagnosis, we followed all patients for at least 2 years to evaluate tumor recurrence and nail deformity. Results In 5 patients, cold sensitivity was the only symptom; no physical finding was suggestive of a glomus tumor. Tenderness was evidenced by the 2 patients who lacked cold sensitivity. None of the 7 patients exhibited CT or MRI abnormalities, but small acoustic shadows were evident in 4 patients, and blood-rich nodules were noted in 2 patients. The mean diameter of the 7 tumors was 2.1 mm, and pathological examination revealed typical glomus bodies. No major surgery-associated complication developed during follow-up. The final mean visual analog scale score (assessing pain) improved to 0.3 from the mean preoperative value of 3.6. Conclusions Small glomus tumors exhibit few traditional symptoms and signs and no definitive radiological CT/MRI finding. However, cold sensitivity alone is a powerful surgical indication, and occasionally, ultrasonographic findings are useful even in the absence of CT/MRI findings.

Long-term Outcomes After Pediatric Free Flap Reconstruction

Introduction Whereas free tissue transfer has evolved to minimize morbidity in adults, less is known about outcomes after free flaps in children. This study sought to assess short- and long-term outcomes after microvascular reconstruction in the pediatric population. Methods Short- and long-term outcomes of free tissue transfer were assessed using chart-review and quality-of-life surveys. The Pediatric Outcomes Data Collection Instrument was used to evaluate overall health, pain, and ability to participate in normal daily and more vigorous activities. Patient or parent responses were compared against normative data. Results Forty-two patients underwent 48 flap reconstructions at a mean age of 8 years. Median follow-up was 14.9 years. Indications included congenital nevi (n = 19, 42%), lymphatic/vascular malformations (n = 8, 19%), and trauma/burns (n = 6, 14%). There were 21 fasciocutaneous (44%), 19 muscle/myocutaneous (40%), 6 fascial/peritoneal (13%), and 2 osteocutaneous flaps (4%). Major flap complications were observed in 4 patients (9%), whereas major donor-site complications occurred in 2% (1 patient). Valid contact information was available for 25 patients; 16 of these completed surveys (64%). Pediatric Outcomes Data Collection Instrument scores for mobility (median, 52), sports/physical functioning (median, 56), happiness (median, 50), and pain/comfort (median, 56) were not significantly different from normative population score of 50. Similarly, median global functioning score was 99 (maximum, 100) and did not differ between flap types. Discussion Free tissue transfer in the pediatric population is reliable and well-tolerated over time. Surgeons should not hesitate to use free flaps when clinically indicated for pediatric patients.

A Systematic Review of Zosteriform Rash in Breast Cancer Patients: An Objective Proof of Flap Reinnervation and a Management Algorithm

Background Zosteriform rash in cancer patients provides objective clues to the process of reinnervation of the reconstructed breast. This rash should also raise suspicion for metastasis, which can be confused with herpes zoster. Objectives The aims of this study were to explain the reconstruction flap sensory reinnervation mechanism based on the clinical findings and provide a diagnostic and management algorithm of zosteriform rash in breast cancer patients. Methods On November 15, 2017, we conducted a search of published articles in MEDLINE and Cochrane databases. All the articles describing a zosteriform rash in a patient with a history of breast cancer were included in this review. Results Eleven articles from the literature and 1 case from our practice were selected for inclusion in this systematic review. Five patients had a breast reconstruction with a flap. The flap skin was affected by the rash in 4 of these patients, providing an objective proof of the reinnervation of the reconstructed breast. In 6 patients, the presentation was typical, and the diagnosis of herpes zoster was made without additional diagnostic testing. In 4 cases, the eruption was atypical, and a biopsy was done to confirm the diagnosis of a cancer metastasis. In 2 patients, the rash was multidermatomal, and a polymerase chain reaction was done to confirm the diagnosis of disseminated herpes zoster. Conclusions Zoster reactivation in breast reconstructed patients is an objective proof of the reinnervation of the skin flap. Moreover, zosteriform rash in cancer patients should raise suspicion for metastasis, which can be confused with herpes zoster.

Long-term Outcomes of Cranioplasty: Titanium Mesh Is Not a Long-term Solution in High-risk Patients

Background Titanium mesh is a popular material for cranioplasty. However, long-term outcomes of these reconstructions remain unknown. We aimed to compare long-term outcomes between patients undergoing both (1) skull reconstruction with titanium mesh and other commonly used cranioplasty materials and (2) scalp reconstructions with locoregional flaps and free tissue transfers. Methods A retrospective review of patients treated with 466 cranioplasties (401 patients) between 2002 and 2014 was performed. Results Materials used for reconstructions included nontitanium alloplast (52.0%), titanium mesh (38%), and autologous bone (10%). Median cranial defect size was 58.4 cm2. Eighty-three reconstructions (18%) included full-thickness scalp defect with a median area of 155.4 cm2. Median follow-up was 3.9 years. Retention rate for isolated cranioplasty was 90%, 89.9%, and 77.1% for titanium mesh, nontitanium alloplast, and autologous bone, respectively (P > 0.05). In composite defect cases, retention rate for autologous bone was comparable, 81.8% (P > 0.05), whereas for titanium mesh and nontitanium alloplast it was significantly lower, 46.8% and 72.0%, respectively (P

Objective The aim of this study was to evaluate work ability and productivity in women who had undergone different types of surgical treatment for breast cancer, as well as breast reconstruction after mastectomy. Methods This cross-sectional study assessed 152 women between 30 and 60 years of age, who worked outside the home in formal or informal jobs, or as self-employed. Thirty-eight of them had no history of breast cancer (control group), and 114 had undergone surgical treatment for breast cancer at least 1 year before their enrollment in the study, and were allocated as follows: mastectomy group (n = 38), breast-conserving surgery group (n = 38), or breast reconstruction breast reconstruction group (n = 38). The validated Brazilian versions of the Work Productivity and Activity Impairment-General Health questionnaire and Work Limitations Questionnaire were self-administered. Results The groups were homogeneous regarding age, education level, and other sociodemographic characteristics. Patients in the mastectomy and breast-conserving surgery groups showed reduced work performance and productivity compared with women in the breast reconstruction and control groups (P = 0.0004 and P = 0.0006, respectively). In addition, women in the mastectomy group had more difficulty in performing activities of daily living compared with those in other groups (P = 0.0121). Conclusions Women who had undergone mastectomy or breast-conserving surgery had decreased work ability and productivity compared with women without a history of breast cancer and to those who had undergone breast reconstruction.

Disparities in Postmastectomy Breast Reconstruction: A Systematic Review of the Literature and Modified Framework for Advancing Research Toward Intervention

Background As the United States' population diversifies, eliminating disparities in health and healthcare has become increasingly important across all disciplines of medicine, including plastic and reconstructive surgery. This is evidenced by the growing body of literature in recent years focusing on disparities in postmastectomy breast reconstruction. No study to date has evaluated whether this research is progressing appropriately to promote tangible evidence-based interventions to reduce these disparities. Methods A systematic literature review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines was performed to identify studies focusing on disparities in postmastectomy breast reconstruction. A previously established public health framework for advancing health disparities research was used to inform analysis of the quality and progression of the included studies. This triphasic framework categorizes disparities research as follows: detecting (identifies and measures disparities in vulnerable populations), understanding (establishes determinants of disparities), or reducing (proposes and evaluates interventions for eliminating disparities). Results Ninety-five studies were identified between 1979 and 2016, with 61 (64.2%) published after 2010. The majority of studies (51.6%) were retrospective cohort or case-control studies (American Society of Plastic Surgery level III evidence). Fifty-eight (63.7%), 31 (34.1%), and 2 (2.2%) studies provided detecting-, understanding- and reducing-phase disparities research, respectively. Non–plastic and reconstructive surgery journals accounted for 70.5% of all articles and for most higher phase research articles, publishing 83.9% and 100% of second and third phase studies, respectively. Disparity categories investigated included race/ethnicity, age, income, insurance status/type, geography, and education level, with race/ethnicity being the most common (73.7%). The most commonly measured outcome was percent of subpopulation receiving reconstruction (63, 66.3%), followed by reconstruction type (14, 16.7%). Patient-, provider-, system-, and research-level factors were all identified as potential targets for interventions to reduce disparities. Conclusions Despite a recent increase in literature focusing on postmastectomy breast reconstruction disparities, the majority focuses on identifying vulnerable populations with inadequate progression to second (understanding) and third (reducing) phases. Increasing research funding, availability of language-concordant and culturally concordant educational materials, and advocacy and sociopolitical awareness within the plastic surgery community is necessary to advance research on postmastectomy breast reconstruction and, ultimately, eliminate it.

Low-Temperature Burn on Replanted Fingers and Free Flaps in Hand

Background Patients who have undergone microsurgery for reconstruction with a free flap or finger replantation are vulnerable to heat injury. Moreover, some of these injuries can occur at low temperatures. Although the temperature does not reach the threshold to cause burns in the adjacent normal tissues, burns can occur in the areas that underwent microsurgery. On the other hand, this type of burn is not completely understood and there are few reports of the clinical prognosis. Methods The medical records of patients who received warm therapy using an infrared heat lamp with the appropriate temperature after hand surgery from January 2009 to December 2016 were reviewed. The patients were classified into 2 groups. Group A comprised patients who underwent free flap or replantation surgery of the hand. Group B comprised patients who underwent other hand surgeries without microsurgery, such as tenorrhaphy, tenolysis, or joint surgery. Through the medical records, all patients with second- or third-degree thermal burns were selected. The relationship between the 2 types of surgery and thermal injury and the timing of the burn after microsurgery were analyzed. Results Groups A and B were composed of 370 (mean age, 48.2 years) and 7010 patients (mean age, 44.5 years), respectively. Burns requiring treatment occurred in 4 patients in group A and in 1 patient in group B. The proportion of low-temperature burns was 4 of 370 in group A and 1 of 7010 in group B. The occurrence of low-temperature burns was more associated with patients who had undergone microsurgery for a hand reconstruction with free flap or finger replantation (P

Outcome Analysis of Metacarpal and Phalangeal Fixation Techniques at Bellevue Hospital

Purpose Phalangeal fractures represent a significant portion of upper extremity injuries but are not well studied as a single entity. We define our approach at a level 1 trauma center and determine whether plating or lag screws (ie, rigid fixation) have superior functional outcomes compared with Kirschner wire fixation for phalangeal or metacarpal fractures. Methods We performed a systematic review of all surgically managed hand fracture cases at Bellevue Hospital during 2012 and 2013. Demographics, type of fixation, length of operation, period of immobilization, range of motion, time to return to work, and complications including reoperation were noted. Comparisons were assessed for significance using Student t tests and Fisher exact test (P 0.05). Total active motion and return to work were similar regardless of type of intervention in both fracture types. No patients treated with rigid fixation required reoperation. Conclusions To our best knowledge, this is the first review to study phalangeal fractures concurrently but also separately from metacarpal fractures. Despite shorter periods of immobilization, rigid fixation does not appear to lead to improved total active motion or time to return to work.

Medial Plantar Venous Flap: Classic Donor Site Modification for Hand Defects

Background Destruction of digits from trauma results in a much more significant influence on patients' mental state and quality of life than do injuries to other parts. The purpose of this study was to describe a novel modification of medial plantar venous flap for soft tissue defects in the hands and digits. Methods Nine patients received medial plantar venous flap to resurface soft tissue defects in the hands or digits between January 2015 and February 2017. This flap can be used either in a free-island pattern or in a flow-through pattern through the medial branch of the great saphenous vein. All patient data including preoperative statues and follow-up examinations (flap survival rates, complication rates, total active motion, static 2-point discrimination, and Semme-Weinstein test score) were analyzed. Results We included 6 men and 3 women, with a mean age of 34.2 years. The medial plantar venous flaps were used for vascularization in 5 patients because of segmental defects of bilateral digit arteries. Eight flaps survived uneventfully in this study. One flap partially failed (20% of the flap area) because of venous congestion. The functional outcomes and sensory restoration were satisfied for all 9 flaps. Conclusions Compared with the traditional medial plantar flap, the medial plantar venous flap involves a simpler surgical procedure and allows for revascularization of distal areas using the flow-through technique. Furthermore, the medial plantar area presents a sensitive, glabrous skin with proper bulkiness and allows for movement of the underlying structure.

Surgical Resection of Occult Subungual Glomus Tumors: Cold Sensitivity and Sonographic Findings

Purpose We surgically treated subungual masses that were suspected glomus tumors, although definitive clinical and radiological findings were lacking. We report the outcomes of a retrospective case series. Methods Of 42 patients treated by surgical resection between March 1996 and December 2015, 7 who met our inclusion/exclusion criteria were evaluated. At least 1 symptom of the typical triad (temperature sensitivity, severe pain, and localized tenderness) was absent, and computed tomography (CT) and magnetic resonance imaging (MRI) findings were normal. After ultrasonographic evaluation, we resected the masses using a transungual approach or a nail-preserving method. After pathological confirmation of the diagnosis, we followed all patients for at least 2 years to evaluate tumor recurrence and nail deformity. Results In 5 patients, cold sensitivity was the only symptom; no physical finding was suggestive of a glomus tumor. Tenderness was evidenced by the 2 patients who lacked cold sensitivity. None of the 7 patients exhibited CT or MRI abnormalities, but small acoustic shadows were evident in 4 patients, and blood-rich nodules were noted in 2 patients. The mean diameter of the 7 tumors was 2.1 mm, and pathological examination revealed typical glomus bodies. No major surgery-associated complication developed during follow-up. The final mean visual analog scale score (assessing pain) improved to 0.3 from the mean preoperative value of 3.6. Conclusions Small glomus tumors exhibit few traditional symptoms and signs and no definitive radiological CT/MRI finding. However, cold sensitivity alone is a powerful surgical indication, and occasionally, ultrasonographic findings are useful even in the absence of CT/MRI findings.

A Systematic Review of Zosteriform Rash in Breast Cancer Patients: An Objective Proof of Flap Reinnervation and a Management Algorithm

Background Zosteriform rash in cancer patients provides objective clues to the process of reinnervation of the reconstructed breast. This rash should also raise suspicion for metastasis, which can be confused with herpes zoster. Objectives The aims of this study were to explain the reconstruction flap sensory reinnervation mechanism based on the clinical findings and provide a diagnostic and management algorithm of zosteriform rash in breast cancer patients. Methods On November 15, 2017, we conducted a search of published articles in MEDLINE and Cochrane databases. All the articles describing a zosteriform rash in a patient with a history of breast cancer were included in this review. Results Eleven articles from the literature and 1 case from our practice were selected for inclusion in this systematic review. Five patients had a breast reconstruction with a flap. The flap skin was affected by the rash in 4 of these patients, providing an objective proof of the reinnervation of the reconstructed breast. In 6 patients, the presentation was typical, and the diagnosis of herpes zoster was made without additional diagnostic testing. In 4 cases, the eruption was atypical, and a biopsy was done to confirm the diagnosis of a cancer metastasis. In 2 patients, the rash was multidermatomal, and a polymerase chain reaction was done to confirm the diagnosis of disseminated herpes zoster. Conclusions Zoster reactivation in breast reconstructed patients is an objective proof of the reinnervation of the skin flap. Moreover, zosteriform rash in cancer patients should raise suspicion for metastasis, which can be confused with herpes zoster.

Long-term Outcomes of Cranioplasty: Titanium Mesh Is Not a Long-term Solution in High-risk Patients

Background Titanium mesh is a popular material for cranioplasty. However, long-term outcomes of these reconstructions remain unknown. We aimed to compare long-term outcomes between patients undergoing both (1) skull reconstruction with titanium mesh and other commonly used cranioplasty materials and (2) scalp reconstructions with locoregional flaps and free tissue transfers. Methods A retrospective review of patients treated with 466 cranioplasties (401 patients) between 2002 and 2014 was performed. Results Materials used for reconstructions included nontitanium alloplast (52.0%), titanium mesh (38%), and autologous bone (10%). Median cranial defect size was 58.4 cm2. Eighty-three reconstructions (18%) included full-thickness scalp defect with a median area of 155.4 cm2. Median follow-up was 3.9 years. Retention rate for isolated cranioplasty was 90%, 89.9%, and 77.1% for titanium mesh, nontitanium alloplast, and autologous bone, respectively (P > 0.05). In composite defect cases, retention rate for autologous bone was comparable, 81.8% (P > 0.05), whereas for titanium mesh and nontitanium alloplast it was significantly lower, 46.8% and 72.0%, respectively (P

Ultrasound-guided steroid injection for the treatment of de Quervain’s disease: an anatomy-based approach

Abstract

Objective

To suggest different ultrasound-guided steroid injection (USI) techniques based on anatomical variations of the first extensor compartment (FEC), and to evaluate the usefulness of it, in patients with de Quervain's disease.

Materials and methods

Twenty-eight patients who underwent USI for de Quervain's disease were included. Anatomical variations were classified into complete sub-compartmentalization (n = 11), distal incomplete sub-compartmentalization (n = 5), and no sub-compartmentalization (n = 12) on ultrasound. Involved sub-compartments were recorded in patients with complete sub-compartmentalization. USIs were performed based on the anatomical variations: in both sub-compartments (n = 2) or only in the affected sub-compartment (n = 9) depending on the location of tenosynovitis involvement, in patients with complete sub-compartmentalization; in proximal FEC in patients with distal incomplete sub-compartmentalization (n = 5); in the common compartment in patients with no sub-compartmentalization (n = 12). Medical charts were retrospectively reviewed for evaluation of clinical outcome at follow-up visits.

Results

Twenty-three out of 28 patients were followed up with a mean period of 31.2 days after injection (6~87 days). Mean VAS was 7.96 before injection (range: 4 to 10), which was significantly reduced to 0.65 at rest and 1.57 during activity at follow-up visits (p < 0.05). Twenty-two out of 23 patients were satisfied with the results. The mean proportion of subjective pain reduction was 82.0% (median 95%).

Conclusion

Ultrasound-guided steroid injections using different injection techniques based on the anatomical variations of the FEC have shown to be beneficial in the management of de Quervain's disease.

Metachronous multicentric giant cell tumour of bone

Abstract

Metachronous multicentric giant cell tumour (GCT) of bone is rare. We report a case of a 21-year-old man with metachronous multicentric GCTs, with five (including one recurrence) documented lesions reported over a span of 9 years involving various sites, which included the fifth metacarpal bone of the right hand, the intermediate cuneiform bone of the right foot, the left proximal humerus and the lateral malleolus of the right tibia. The radiological appearance of these lesions in these various sites with correlation among clinical history, histopathology and the treatment approach is described in this report. He is undergoing regular follow-up and has now once again presented with recurrence of the right tibial lesion. The case is reported for its rarity.

Evaluation of articular cartilage following rotational acetabular osteotomy for hip dysplasia using T2 mapping MRI

Abstract

Background

Rotational acetabular osteotomy (RAO) is one of the surgical treatments for acetabular dysplasia, and satisfactory results have been reported. We evaluated the postoperative changes of articular cartilage and whether the pre-operative condition of the articular cartilage influences the clinical results using T2 mapping MRI.

Methods

We reviewed 31 hips with early stage osteoarthritis in 31 patients (mean age, 39.6 years), including three men and 28 women who underwent RAO for hip dysplasia. Clinical evaluations including Japanese Orthopedic Association (JOA) score and Japanese Orthopedic Association Hip Disease Evaluation Questionnaire (JHEQ), and radiographical evaluations on X-ray were performed. Longitudinal qualitative assessment of articular cartilage was also performed using 3.0-T MRI with T2 mapping technique preoperatively, 6 months, and at 1 and 2 years postoperatively.

Results

There was no case with progression of osteoarthritis. The mean JOA score improved from 70.1 to 93.4 points, the mean postoperative JHEQ score was 68.8 points, and radiographical data also improved postoperatively. We found that the T2 values of the cartilage at both femoral head and acetabulum increased at 6 months on coronal and sagittal views. However, they significantly decreased 1 and 2 years postoperatively. The T2 values of the center to anterolateral region of acetabulum negatively correlated with postoperative JHEQ score, particularly in pain score.

Conclusions

This study suggests that biomechanical and anatomical changes could apparently cause decreased T2 values 1–2 years postoperatively compared with those preoperatively. Furthermore, preoperative T2 values of the acetabulum can be prognostic factors for the clinical results of RAO.

Narrowing of ischiofemoral and quadratus femoris spaces in pediatric ischiofemoral impingement

Abstract

Objective

To correlate MRI findings of quadratus femoris muscle edema (QFME) with narrowing of the ischiofemoral space (IFS) and quadratus femoris space (QFS) in children, and to identify threshold values reflecting an anatomic architecture that may predispose to ischiofemoral impingement.

Materials and methods

A case-control retrospective MRI review of 49 hips in 27 children (mean, 13 years) with QFME was compared to 49 hips in 27 gender and age-matched controls. Two radiologists independently measured IFS and QFS. Generalized linear mixed-effects models were fit to compare IFS and QFS values between cases and controls, and adjust for correlation in repeated measures from the same subject. Receiver operating characteristic (ROC) analysis determined optimal threshold values.

Results

Compared to controls, cases had significantly smaller IFS (p < 0.001, both readers) and QFS (reader 1: p < 0.001; reader 2: p = 0.003). When stratified as preteen (< 13) or teenage (≥ 13), lower mean IFS and QFS were observed in cases versus controls in both age groups. Area under ROC curve for IFS and QFS was high in preteens (0.77 and 0.71) and teens (0.94 and 0.88). Threshold values were 14.9 mm (preteens) and 19 mm (teens) for IFS and 11.2 mm (preteens) and 11.1 mm (teens) for QFS. IFS and QFS were modestly correlated with age among controls only.

Conclusions

Pediatric patients with QFME had significantly narrower QFS and IFS compared with controls. IFS and QFS were found to normally increase in size with age. Optimal cutoff threshold values were identified for QFS and IFS in preteens and teenagers.

Acute posterior cruciate ligament injuries: effect of location, severity, and associated injuries on surgical management

Abstract

Objective

To correlate MRI findings of patients with posterior cruciate ligament (PCL) injury and surgical management.

Materials and methods

A retrospective search yielded 79 acute PCL injuries (36 ± 16 years old, 21 F, 58 M). Two independent readers graded PCL tear location (proximal, middle, or distal third) and severity (low-grade or high-grade partial/complete) and evaluated injury of other knee structures. When available, operative reports were examined and the performed surgical procedure was compared with injury grade, location, and presence of associated injuries.

Results

The most commonly injured knee structures in acute PCL tears were posterolateral corner (58/79, 73%) and anterior cruciate ligament (ACL) (48/79, 61%). Of the 64 patients with treatment information, 31/64 (48%) were managed surgically: 12/31 (39%) had PCL reconstruction, 13/31 (42%) had ACL reconstruction, 10/31 (32%) had posterolateral corner reconstruction, 9/31 (29%) had LCL reconstruction, 8/31 (26%) had meniscectomy, and 8/31 (26%) had fixation of a fracture. Proximal third PCL tear and multiligamentous injury were more commonly associated with surgical management (P < 0.05). Posterolateral and posteromedial corner, ACL, collateral ligament, meniscus, patellar retinaculum, and gastrocnemius muscle injury, and fracture were more likely to result in surgical management (P < 0.05). Patients with high-grade partial/complete PCL tear were more likely to have PCL reconstruction as a portion of surgical management (P < 0.05).

Conclusions

Location of PCL tear and presence of other knee injuries were associated with surgical management while high-grade/complete PCL tear grade was associated with PCL reconstruction. MRI reporting of PCL tear location, severity, and of other knee structure injuries is important for guiding clinical management.

Ultrasound measurements of axillary recess capsule thickness in unilateral frozen shoulder: study of correlation with MRI measurements

Abstract

Objective

The aims of this study were to compare the ultrasound thickness of the affected axillary recess capsule (ARC) with that of the unaffected ARC in patients with frozen shoulder (FS), to analyze whether the ultrasound measurements of the ARC thickness correlate with those obtained using MRI, and to assess whether the ultrasound thickness of the ARC correlates with the patterns of range of motion limitation.

Materials and methods

Forty-four patients with clinically diagnosed unilateral FS and MRI evaluation performed ultrasound measurement of ARC. The ultrasound measurement of the ARC thickness was performed with the patients in a supine position with their shoulder abducted by 40°. The ARC thickness was also measured by MRI on oblique coronal images by another physician blinded to the ultrasound measurements. With both ultrasound and MRI, ARC thickness was determined at the widest portion of the capsule.

Results

The ultrasound thickness of ARC was significantly higher in the affected shoulder (4.4 ± 1.1 mm) than in the unaffected one (2.2 ± 0.5 mm) (p < 0.001). The ultrasound thickness of the ARC in the affected shoulder correlated with that measured by MRI (8.9 ± 1.9 mm) (p < 0.001, r = 0.83). The ARC thickness, whether measured by ultrasound or MRI, was not significantly related to the limitation of movement in specific directions.

Conclusion

Ultrasound can demonstrate the difference in ARC thickness between affected and unaffected shoulders in patients with unilateral FS. The ARC thickness measured by ultrasound correlates with that measured by MRI.

Fibrous dysplasia: an unusual case of a very aggressive form with costo-vertebral joint destruction and invasion of the contralateral D7 vertebral body

Abstract

Fibrous dysplasia (FD) is a benign fibro-osseous disease of the bone that may be solitary or multicentric. It is important to distinguish this type of lesion from low-grade osteosarcomas (LGOS) and from secondary sarcomas, because malignant transformation has rarely been reported. It is classically described as having a ground-glass appearance, endosteal scalloping, and thinning of the cortex. Cortical disruption is considered evidence of malignancy, but it can also be present in benign FD with aggressive behavior. We present an unusual case of aggressive FD of the 7th left rib, already diagnosed more than 22 years ago, where cortical and costo-vertebral joint disruption and 7th thoracic vertebral body involvement were not evidence of malignant behavior. From a histological perspective, FD and LGOS are similar; even if histology is of fundamental importance, the diagnosis has to be made based on the clinical and radiological aspects as well, although at imaging, differentiation between FD and LGOS can be difficult. In the present case, even though the histological examination suggested a benign lesion, the radiological examination instead consistently suggests malignancy. It is for this reason that there should be a high index of suspicion during follow-up and a new biopsy should be scheduled in case any changes occur during follow-up.

Non-union rate of type II and III odontoid fractures in CPPD versus a control population

Abstract

Objective

The objective was to determine if there is a significant difference between rates of non-union of type II and III odontoid fractures in patients with calcium pyrophosphate dihydrate deposition (CPPD) compared with a control population.

Materials and methods

A 10-year retrospective picture archive and communications system review was performed of 31 CPPD patients and 31 control patients. Imaging studies were reviewed for radiographic or CT evidence of osseous union and complications.

Results

There was a significant difference in the rates of non-union between the two groups, with the non-union rate reaching 90.3% in the CPPD group and 32% in the control group. Comparing the degree of displacement and angulation of the two groups did not show a significant difference.

Conclusion

The results indicate that odontoid fracture non-union rates are significantly higher in CPPD patients and should be taken into consideration when diagnosing odontoid fractures and deciding on appropriate treatment.

Abstract

Objective

To suggest different ultrasound-guided steroid injection (USI) techniques based on anatomical variations of the first extensor compartment (FEC), and to evaluate the usefulness of it, in patients with de Quervain's disease.

Materials and methods

Twenty-eight patients who underwent USI for de Quervain's disease were included. Anatomical variations were classified into complete sub-compartmentalization (n = 11), distal incomplete sub-compartmentalization (n = 5), and no sub-compartmentalization (n = 12) on ultrasound. Involved sub-compartments were recorded in patients with complete sub-compartmentalization. USIs were performed based on the anatomical variations: in both sub-compartments (n = 2) or only in the affected sub-compartment (n = 9) depending on the location of tenosynovitis involvement, in patients with complete sub-compartmentalization; in proximal FEC in patients with distal incomplete sub-compartmentalization (n = 5); in the common compartment in patients with no sub-compartmentalization (n = 12). Medical charts were retrospectively reviewed for evaluation of clinical outcome at follow-up visits.

Results

Twenty-three out of 28 patients were followed up with a mean period of 31.2 days after injection (6~87 days). Mean VAS was 7.96 before injection (range: 4 to 10), which was significantly reduced to 0.65 at rest and 1.57 during activity at follow-up visits (p < 0.05). Twenty-two out of 23 patients were satisfied with the results. The mean proportion of subjective pain reduction was 82.0% (median 95%).

Conclusion

Ultrasound-guided steroid injections using different injection techniques based on the anatomical variations of the FEC have shown to be beneficial in the management of de Quervain's disease.

Widespread and debilitating hemangiomas in a patient with enchondromatosis and D-2-hydroxyglutaric aciduria

Abstract

Metaphyseal chondromatosis with D-2-hydroxyglutaric aciduria (MC-HGA) (OMIM 614875) is a severe chondrodysplasia combined with a urinary excretion of D-2-hydroxyglutaric acid. Here, we reported the tenth case of this disease. A 15-year-old boy had symmetric radiolulencies in the metaphyses of the long bones suggesting enchondromatosis and platyspondyly. Remarkably, he manifested widespread cavernous hemangiomas including scalp, lips, tongue, larynx, and prepuce, with the onset of 3 years of age. Hemangiomas at the larynx had caused dyspnea and those in the oral cavity led to recurrent bleeding, requiring several surgical removals. These multiple and debilitating hemangiomas have never been previously reported in patients with MC-HGA. Mutation analyses including Sanger sequencing of genes involving in enchondromatosis and the metabolic pathway of D-2-hydroxyglutarate including PTHR1, D2HGDH, HOT, and IDH1, as well as whole-exome sequencing for proband-parent trio analysis and paired blood versus hemangioma studies showed no pathogenic variants. In summary, we reported the tenth patient with MC-HGA who manifested widespread and debilitating hemangiomas in several organs, expanding the clinical spectrum of MC-HGA.

Acute posterior cruciate ligament injuries: effect of location, severity, and associated injuries on surgical management

Abstract

Objective

To correlate MRI findings of patients with posterior cruciate ligament (PCL) injury and surgical management.

Materials and methods

A retrospective search yielded 79 acute PCL injuries (36 ± 16 years old, 21 F, 58 M). Two independent readers graded PCL tear location (proximal, middle, or distal third) and severity (low-grade or high-grade partial/complete) and evaluated injury of other knee structures. When available, operative reports were examined and the performed surgical procedure was compared with injury grade, location, and presence of associated injuries.

Results

The most commonly injured knee structures in acute PCL tears were posterolateral corner (58/79, 73%) and anterior cruciate ligament (ACL) (48/79, 61%). Of the 64 patients with treatment information, 31/64 (48%) were managed surgically: 12/31 (39%) had PCL reconstruction, 13/31 (42%) had ACL reconstruction, 10/31 (32%) had posterolateral corner reconstruction, 9/31 (29%) had LCL reconstruction, 8/31 (26%) had meniscectomy, and 8/31 (26%) had fixation of a fracture. Proximal third PCL tear and multiligamentous injury were more commonly associated with surgical management (P < 0.05). Posterolateral and posteromedial corner, ACL, collateral ligament, meniscus, patellar retinaculum, and gastrocnemius muscle injury, and fracture were more likely to result in surgical management (P < 0.05). Patients with high-grade partial/complete PCL tear were more likely to have PCL reconstruction as a portion of surgical management (P < 0.05).

Conclusions

Location of PCL tear and presence of other knee injuries were associated with surgical management while high-grade/complete PCL tear grade was associated with PCL reconstruction. MRI reporting of PCL tear location, severity, and of other knee structure injuries is important for guiding clinical management.

Sonographic sequential change of the anteroinferior labrum following arthroscopic Bankart repair: quantitative and qualitative assessment

Abstract

Objective

Although arthroscopic Bankart repair is widely performed, little is known concerning the healing process of the Bankart lesion. This study aimed to describe the sonographic sequential change of the anteroinferior labrum following arthroscopic Bankart repair, both quantitatively and qualitatively.

Materials and Methods

Twenty-five subjects who had undergone arthroscopic Bankart repair were investigated using a sonographic diagnostic device equipped with shear-wave elastographic technology. In addition to measuring the elasticity of the anteroinferior labrum, the B-mode echogram of the anteroinferior labrum was classified into three grades based on the relative echogenicity. Assessment was performed in the affected shoulder 1, 2, 3, 4, 5, 6, and 12 months postoperatively and in the contralateral shoulder 1 month postoperatively for the control.

Results

The mean elasticity of the anteroinferior labrum in the affected shoulder 1 and 2 months postoperatively was significantly lower than in the contralateral shoulder (p < 0.001 for both). However, no significant difference was found after 3 months postoperatively. B-mode echograms of the anteroinferior labrum in the contralateral shoulder were classified as grade 0 in all subjects (100%), whereas the percentage of grade 0s in the affected shoulder was 0, 4, 96, and 100% at 1, 2, 3, and 4 months postoperatively.

Conclusion

Both quantitative and qualitative assessment of repaired anteroinferior labrum using ultrasound became comparable with the contralateral shoulder 3–4 months postoperatively. Ultrasound is a useful decision-supporting tool to prescribe postoperative rehabilitation protocol following arthroscopic Bankart repair, although functional recovery should also be evaluated on an individual basis.

Three-material decomposition with dual-layer spectral CT compared to MRI for the detection of bone marrow edema in patients with acute vertebral fractures

Abstract

Objectives

To assess whether bone marrow edema in patients with acute vertebral fractures can be accurately diagnosed based on three-material decomposition with dual-layer spectral CT (DLCT).

Materials and methods

Acute (n = 41) and chronic (n = 18) osteoporotic thoracolumbar vertebral fractures as diagnosed by MRI (hyperintense signal in STIR sequences) in 27 subjects (72 ± 11 years; 17 women) were assessed with DLCT. Spectral data were decomposed into hydroxyapatite, edema-equivalent, and fat-equivalent density maps using an in-house-developed algorithm. Two radiologists, blinded to clinical and MR findings, assessed DLCT and conventional CT independently, using a Likert scale (1 = no edema; 2 = likely no edema; 3 = likely edema; 4 = edema). For DLCT and conventional CT, accuracy, sensitivity, and specificity for identifying acute fractures (Likert scale, 3 and 4) were analyzed separately using MRI as standard of reference.

Results

For the identification of acute fractures, conventional CT showed a sensitivity of 0.73–0.76 and specificity of 0.78–0.83, whereas the sensitivity (0.93–0.95) and specificity (0.89) of decomposed DLCT images were substantially higher. Accuracy increased from 0.76 for conventional CT to 0.92–0.93 using DLCT. Interreader agreement for fracture assessment was high in conventional CT (weighted κ [95% confidence interval]; 0.81 [0.70; 0.92]) and DLCT (0.96 [0.92; 1.00]).

Conclusions

Material decomposition of DLCT data substantially improved accuracy for the diagnosis of acute vertebral fractures, with a high interreader agreement. This may spare patients additional examinations and facilitate the diagnosis of vertebral fractures.

Ultrasound measurements of axillary recess capsule thickness in unilateral frozen shoulder: study of correlation with MRI measurements

Abstract

Objective

The aims of this study were to compare the ultrasound thickness of the affected axillary recess capsule (ARC) with that of the unaffected ARC in patients with frozen shoulder (FS), to analyze whether the ultrasound measurements of the ARC thickness correlate with those obtained using MRI, and to assess whether the ultrasound thickness of the ARC correlates with the patterns of range of motion limitation.

Materials and methods

Forty-four patients with clinically diagnosed unilateral FS and MRI evaluation performed ultrasound measurement of ARC. The ultrasound measurement of the ARC thickness was performed with the patients in a supine position with their shoulder abducted by 40°. The ARC thickness was also measured by MRI on oblique coronal images by another physician blinded to the ultrasound measurements. With both ultrasound and MRI, ARC thickness was determined at the widest portion of the capsule.

Results

The ultrasound thickness of ARC was significantly higher in the affected shoulder (4.4 ± 1.1 mm) than in the unaffected one (2.2 ± 0.5 mm) (p < 0.001). The ultrasound thickness of the ARC in the affected shoulder correlated with that measured by MRI (8.9 ± 1.9 mm) (p < 0.001, r = 0.83). The ARC thickness, whether measured by ultrasound or MRI, was not significantly related to the limitation of movement in specific directions.

Conclusion

Ultrasound can demonstrate the difference in ARC thickness between affected and unaffected shoulders in patients with unilateral FS. The ARC thickness measured by ultrasound correlates with that measured by MRI.

Fibrous dysplasia: an unusual case of a very aggressive form with costo-vertebral joint destruction and invasion of the contralateral D7 vertebral body

Abstract

Fibrous dysplasia (FD) is a benign fibro-osseous disease of the bone that may be solitary or multicentric. It is important to distinguish this type of lesion from low-grade osteosarcomas (LGOS) and from secondary sarcomas, because malignant transformation has rarely been reported. It is classically described as having a ground-glass appearance, endosteal scalloping, and thinning of the cortex. Cortical disruption is considered evidence of malignancy, but it can also be present in benign FD with aggressive behavior. We present an unusual case of aggressive FD of the 7th left rib, already diagnosed more than 22 years ago, where cortical and costo-vertebral joint disruption and 7th thoracic vertebral body involvement were not evidence of malignant behavior. From a histological perspective, FD and LGOS are similar; even if histology is of fundamental importance, the diagnosis has to be made based on the clinical and radiological aspects as well, although at imaging, differentiation between FD and LGOS can be difficult. In the present case, even though the histological examination suggested a benign lesion, the radiological examination instead consistently suggests malignancy. It is for this reason that there should be a high index of suspicion during follow-up and a new biopsy should be scheduled in case any changes occur during follow-up.

Non-union rate of type II and III odontoid fractures in CPPD versus a control population

Abstract

Objective

The objective was to determine if there is a significant difference between rates of non-union of type II and III odontoid fractures in patients with calcium pyrophosphate dihydrate deposition (CPPD) compared with a control population.

Materials and methods

A 10-year retrospective picture archive and communications system review was performed of 31 CPPD patients and 31 control patients. Imaging studies were reviewed for radiographic or CT evidence of osseous union and complications.

Results

There was a significant difference in the rates of non-union between the two groups, with the non-union rate reaching 90.3% in the CPPD group and 32% in the control group. Comparing the degree of displacement and angulation of the two groups did not show a significant difference.

Conclusion

The results indicate that odontoid fracture non-union rates are significantly higher in CPPD patients and should be taken into consideration when diagnosing odontoid fractures and deciding on appropriate treatment.

MR arthrogram of the postoperative glenoid labrum: normal postoperative appearance versus recurrent tears

Abstract

Objective

The purpose of this study is to describe the MR arthrogram appearance of the postoperative glenoid labrum and to describe the features consistent with recurrent tear.

Materials and Methods

We identified 30 patients who had undergone glenoid labral repair, had a subsequent MR arthrogram of his or her shoulder, and went on to repeat shoulder arthroscopy. Each MR arthrogram was reviewed blindly, and the glenoid labrum was described as normal, irregular, or torn. Additional findings recorded included the presence or absence of a paralabral cyst and suture anchors in the glenoid. The operative report was also reviewed for each patient to determine the status of the labrum at arthroscopy.

Results

Following consensus review, 18/30 MRIs were felt to demonstrate recurrent glenoid labral tear, 11/30 showed an irregular labrum, and 1/30 was called normal. The radiology impression regarding the presence or absence of a recurrent glenoid labral tear agreed with the operative report in 24/30 (80%) cases, and was discrepant in six. This equals 83.3% sensitivity and 81.8% specificity of MR arthrogram in the diagnosis of recurrent labral tear in this study. A paralabral cyst was present in 3/30 (10%) cases, all three of which were torn.

Conclusions

MR arthrogram findings of signal equal to gadolinium or fluid within or underlying the glenoid labrum and markedly diminutive or absent labrum were the most useful features to diagnose recurrent tear. Some signal underlying the labrum, which is confined to the anterosuperior quadrant, may be normal. The secondary finding of a paralabral cyst was also highly sensitive for recurrent tear.

Surveillance MRI for the detection of locally recurrent Ewing sarcoma seems futile

Abstract

Purpose

To determine the frequency of locally recurrent Ewing sarcoma on surveillance MRI and the outcome of these patients.

Materials and methods

This retrospective single-center study included all patients with newly diagnosed Ewing sarcoma who underwent surveillance MRI of the primary tumor location after primary treatment between 1997 and 2016.

Results

Thirty-two patients underwent a total of 176 local surveillance MRI scans, yielding an average of 5.5 ± 4.4 MRI scans per patient. Follow-up time of surveillance MRI after completion of primary treatment ranged between 1 and 111 months. Surveillance MRI detected five (15.6%) locally recurrent Ewing sarcomas, at 2, 4, 6, 6, and 7 months after completion of primary treatment, of whom three also had simultaneous recurrent (metastatic) disease elsewhere. Two patients had recurrent metastatic disease without any signs of locally recurrent disease on surveillance MRI. All five patients with locally recurrent disease on surveillance MRI died, at 2, 4, 5, 8, and 9 months after local recurrence detection. Patients with locally recurrent disease had a significantly worse overall survival than patients without locally recurrent disease (log-rank test, P < 0.0001).

Conclusions

A limited number of patients have locally recurrent Ewing sarcoma on surveillance MRI. These patients often have simultaneous recurrent (metastatic) disease elsewhere, and their outcome is poor. Moreover, some patients present without locally recurrent disease on MRI but disease recurrence elsewhere. Therefore, surveillance MRI currently seems to have little value and should be reconsidered, also given the costs and the repeated exposure of surviving patients to gadolinium-based contrast agents.

The lucent (CT) and enhancing (MR) rim, a sign of Paget’s disease of the skull: case report

Abstract

Osteoporosis circumscripta is sometimes observed at the skull vault and corresponds to the initial stage of Paget's disease of the bone. Differentiating osteoporosis circumscripta from other reasons for osteolytic images of the vault may be difficult. We report a case of osteoporosis circumscripta of the frontal bone. A lucent rim seen on CT scan, which was enhanced on gadolinium-enhanced MRI, delineated the abnormal bone. The patient was a 50-year-old woman who had CT scans of the skull for chronic sinusitis. Pathology examination showed typical bone changes of Paget's disease. The lucent and enhancing rim sign may help in differentiating Paget's disease from other conditions.

Widespread and debilitating hemangiomas in a patient with enchondromatosis and D-2-hydroxyglutaric aciduria

Abstract

Metaphyseal chondromatosis with D-2-hydroxyglutaric aciduria (MC-HGA) (OMIM 614875) is a severe chondrodysplasia combined with a urinary excretion of D-2-hydroxyglutaric acid. Here, we reported the tenth case of this disease. A 15-year-old boy had symmetric radiolulencies in the metaphyses of the long bones suggesting enchondromatosis and platyspondyly. Remarkably, he manifested widespread cavernous hemangiomas including scalp, lips, tongue, larynx, and prepuce, with the onset of 3 years of age. Hemangiomas at the larynx had caused dyspnea and those in the oral cavity led to recurrent bleeding, requiring several surgical removals. These multiple and debilitating hemangiomas have never been previously reported in patients with MC-HGA. Mutation analyses including Sanger sequencing of genes involving in enchondromatosis and the metabolic pathway of D-2-hydroxyglutarate including PTHR1, D2HGDH, HOT, and IDH1, as well as whole-exome sequencing for proband-parent trio analysis and paired blood versus hemangioma studies showed no pathogenic variants. In summary, we reported the tenth patient with MC-HGA who manifested widespread and debilitating hemangiomas in several organs, expanding the clinical spectrum of MC-HGA.
