Investigation Into the Effects of Intra-Articular Steroid on Post-Traumatic Osteoarthritis in Distal Radius Fractures: A Randomized Controlled Pilot Study.

PURPOSE: The aim of this prospective, randomized, controlled, double-blinded pilot study was to determine the rates of post-traumatic osteoarthritis and assess joint space width in the presence or absence of a single intra-articular injection of corticosteroid after an acute, intra-articular distal radius fracture (DRF). METHODS: Forty patients received a single, intra-articular, radiocarpal joint injection of 4 mg of dexamethasone (DEX) (n = 19) or normal saline placebo (n = 21) within 2 weeks of a surgically or nonsurgically treated intra-articular DRF. The primary outcome measure was minimum radiocarpal joint space width (mJSW) on noncontrast computed tomography scans at 2 years postinjection. Secondary outcomes were obtained at 3 months, 6 months, 1 year, and 2 years postinjection and included Disabilities of the Arm, Shoulder, and Hand; Michigan Hand Questionnaire; Patient-Rated Wrist Evaluation; wrist range of motion; and grip strength. RESULTS: At 2-year follow-up, there was no difference in mean mJSW between the DEX group (2.2 mm; standard deviation, 0.6; range, 1.4-3.2) and the placebo group (2.3 mm; standard deviation, 0.7; range, 0.9-3.9). Further, there were no differences in any secondary outcome measures at any postinjection follow-up interval. CONCLUSIONS: Radiocarpal joint injection of corticosteroid within 2 weeks of an intra-articular DRF does not appear to affect the development of post-traumatic osteoarthritis within 2 years follow-up in a small pilot cohort. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic II.

Microvascular Free Flap Reconstruction of Thigh Defects After Tumor Resection in the Setting of Radiation.

BACKGROUND: Soft tissue reconstruction of the thigh defects can usually be achieved with local options. Free tissue transfer may be indicated in very large defects with exposed vital structures and/or a history of radiation therapy where the healing potential of local option is poor. In this study, we evaluated our experience on microsurgical reconstruction of oncological and irradiated thigh defects to assess the risk factors for complications. METHODS: Institutional review board-approved retrospective case series study using electronic medical records from 1997 to 2020 was conducted. All patients with irradiated thigh defects derived from oncological resections who underwent microsurgical reconstruction were included. Patient demographics and clinical and surgical characteristics were recorded. RESULTS: Twenty free flaps were transferred in 20 patients. Mean age was 60 ± 11.8 years, and median follow-up time was 24.3 months (interquartile range [IQR], 71.4-9.2 months). The most common type of cancer was liposarcoma (n = 5). Neoadjuvant radiation therapy was performed in 60%. Most commonly used free flaps were latissimus dorsi muscle/musculocutaneous flap (n = 7) and anterolateral thigh flap (n = 7) Nine flaps were transferred immediately after resection. Overall, 70% of arterial anastomoses were end-to-end, whereas 30% were end-to-side. Deep femoral artery branches were chosen as the recipient artery in the 45%. Median length of hospital stay was 11 days (IQR, 16.0-8.3 days), and median time to start weight-bearing was 20 days (IQR, 49.0-9.5 days). All were successful except for 1 patient who required additional pedicled flap coverage. The overall major-complication rate was 25% (n = 5, hematoma = 2, venous congestion requiring emergent exploration surgery = 1, wound dehiscence = 1, surgical site infection = 1). Cancer recurred in 3 patients. One required amputation due to cancer recurrence. Age (hazard ratio [HR], 1.14; P = 0.0163), tumor volume (HR, 18.8; P = 0.0006), and resection volume (HR, 2.24; P = 0.0019) were statistically significantly associated with having a major complication. CONCLUSIONS: Based on the data, microvascular reconstruction of irradiated post-oncological resection defects shows high flap survival rate and success. Given the large size of flap required, the complex nature and size of these wounds, and history of radiation, wound healing complications are common. Despite this, free flap reconstruction should be considered in irradiated thighs with large defects. Studies with larger cohort and longer follow-up are still required.

Transnasal tension suture of external nasal splints: A reliable, novel technique.

BACKGROUND: We routinely apply external nasal splints after closed nasal reduction or rhinoplasty and secure the splint by transnasal suturing. We seek to describe our technique and review our experience. METHODS: A retrospective chart review was performed to review patients who had an external nasal splint secured by transnasal suturing. The technique consists of steristrips applied across the dorsum and nasal bones. The Aquaplast is molded to the nose and a 2-0 polypropylene suture on a straightened tapered needle or a Keith needle is passed through the splint, the nasal sidewalls and septum, through the splint on the contralateral side, and back again in a horizontal mattress fashion. The suture is tied down to maintain the desired shape of the splint. The splint is removed in the first postoperative followup (10-14 days). RESULTS: Mean patient age was 31.5 years, 82 male and 18 female patients were reviewed, 67 % of splints were placed for closed reduction of acute nasal trauma, and 33 % placed after elective rhinoplasty for late correction of functional and cosmetic traumatic deformity. No splints were inadvertently removed by patients prior to followup. Splints were removed an average of 12 days postoperatively, and mean followup was 27 weeks. There were no complications related to transnasal suturing of the splint, such as skin ulceration, pressure necrosis, identifiable scarring related to the suture entry points or breathing difficulty attributable to internal nasal valve narrowing. CONCLUSION: Transnasal suturing is a safe and reliable method for fixation of an external nasal splint.

Pubectomy and urinary reconstruction provides definitive treatment of urosymphyseal fistula following prostate cancer treatment.

OBJECTIVE: To describe the natural history, reconstructive solutions, and functional outcomes of those men undergoing pubectomy and urinary reconstruction after prostate cancer treatment. PATIENTS AND METHODS: This study retrospectively identified 25 patients with a diagnosis of urosymphyseal fistula (UF) following prostate cancer therapy who were treated with urinary reconstruction with pubectomy. This study describes the natural history, reconstructive solutions, and functional outcomes of this cohort. RESULTS: All 25 patients had a history of pelvic radiotherapy for prostate cancer. The median (interquartile range [IQR]) time from prostate cancer treatment to diagnosis of UF was 11 (6, 16.5) years. The vast majority of men (24/25; 96%) presented with debilitating groin pain during ambulation. Posterior urethral stenosis was common (20/25; 80%), with 60% having repetitive endoscopic treatments. Culture of pubic bone specimens demonstrated active infection in 80%. Discordance between preoperative urine and intraoperative bone cultures was common, 21/22 (95.5%). After surgery, major 90-day complications (Clavien-Dindo Grade III and IV) occurred in eight (32%) patients. Pain was significantly improved, with resolution of pain (24/25; 96%) and restoration of function, the median (IQR) preoperative Eastern Cooperative Oncology Group Performance Status (ECOG PS) was 3 (2, 3) vs median postoperative ECOG PS score of 0 (0, 1). CONCLUSION: Endoscopic urethral manipulation after radiation for prostate cancer is a risk factor for UF. Conservative management will not provide symptom resolution. Fistula decompression, bone resection, and urinary reconstruction effectively treats chronic infection, improves pain and ECOG PS scores.

Comparison of flap reconstruction for soft tissue sarcomas of the foot and ankle.

BACKGROUND: Foot and ankle soft tissue sarcomas (STS) are challenging for reconstruction due to limited surrounding soft tissue and weight-bearing requirements. Currently, there is a paucity of data examining the outcome of flap reconstruction following resection of a foot and ankle sarcoma. METHODS: We reviewed 44 (31 female, 13 male) patients with STS arising from the ankle or foot which required coverage in the form of a free (n = 21), pedicled (n = 13), or rotational perforator flap (n = 10). The mean tumor size was 6 ± 5 cm, with 39 (89%) patients receiving radiotherapy. The mean follow-up was 10 ± 7 years. RESULTS: There were no cases of amputation due to flap failure, with a 10-year limb salvage rate of 84%. Complications occurred in 19 (43%) patients, most commonly wound infections. There was no difference in the incidence of complications between patients undergoing a free flap and pedicled or perforator flap (odds ratio = 0.97, p = 1.0); with no difference in the mean Musculoskeletal Tumor Society (MSTS) score between patients with a free flap versus a pedicled/perforator flap (84% vs. 76%, p = 0.11). CONCLUSION: Flap reconstruction is an essential part of limb salvage for foot and ankle STS. At final follow-up nearly all the patients are ambulatory with an acceptable MSTS score.

Extremity free fillet flap for reconstruction of massive oncologic resection-Surgical technique and outcomes.

BACKGROUND AND OBJECTIVES: The purpose of this study is to present our experience using free fillet flaps to reconstruct massive oncologic defects of the upper and lower extremity. METHODS: A retrospective chart review was performed to include patients who underwent oncologic resection followed by reconstruction using free fillet flaps from July 2001 to October 2018. Patient demographics, clinical and surgical characteristics, and postoperative complications were reviewed. RESULTS: In total, 12 patients were identified and included in this study. Mean age was 48.9 years old. Five patients had extended forequarter amputations and seven patients had external hemipelvectomies, all for locally advanced tumors. Mean tumor size was 15 ± SD 6.4 cm, and negative tumor margins were achieved in all the patients. Mean flap size was 1028 ± SD 869 cm2 . The mean follow-up was 13 months. There were no partial or total flap losses in the postoperative period. Two patients had flap-related postoperative complications, including flap bleeding and wound dehiscence. Median survival was 18 months. CONCLUSION: The free fillet flap is a safe, reliable, and valuable approach for reconstructing oncological defects. It offers the advantage of avoiding donor site morbidity, while providing extensive soft-tissue coverage as a one-step solution for massive oncologic defects.

Long-term clinical and patient-reported outcomes in free flap reconstruction of the weight-bearing heel pad and non-weight-bearing Achilles tendon regions.

BACKGROUND: The non-weight-bearing (NWB) Achilles tendon and weight-bearing (WB) heel pad regions are technically challenging to reconstruct with distinct functional and aesthetic considerations that have not been previously considered in the literature. This study is the first to characterize the long-term clinical and patient-reported outcomes of these components to better inform patients about the postreconstruction period. METHODS: A retrospective review of medical records and phone-based survey of adult patients who underwent free flap reconstruction of the heel/ankle with 6-month minimum clinical follow-up was performed. RESULTS: Forty-three patients, with 31 (72.1%) NWB and 12 (27.9%) WB defects, treated from January 1, 2000 to February 28, 2017 were included. Muscle flaps were more common than fasciocutaneous flaps (N = 36 [83.7%] vs. 7 [16.3%]). Flap survival rate was 95.3% and limb salvage rate was 93.0% at median follow-up of 12.0 months (interquartile range [IQR] 6.2, 25.5). Flap ulceration occurred more frequently in the WB region (41.7 vs. 6.5%, p = .0123). The survey response rate was 63.6%. The majority of patients complete daily tasks with no/little impairment (76.2%), walk half a mile or more (85.7%), returned to work (86.6%), and fit shoes "fair" or "well" (71.4%). Most patients were "very satisfied" with heel/ankle function (71.4%) and would "very likely" undergo the same procedure if needed (76.2%). CONCLUSIONS: Free flap reconstruction in both the NWB Achilles tendon and WB heel pad has excellent limb salvage and flap survival rates. Patients were satisfied with heel/ankle function, but additional counseling is recommended for variance in appearance and higher ulceration rates in WB defects.

Surgical Outcomes after Abdominoperineal Resection with Sacrectomy and Soft Tissue Reconstruction: Lessons Learned.

BACKGROUND: Abdominoperineal resection (APR), which involves resection of the rectum, anal canal, and perianal skin, results in a large dead space in the pelvis, devascularized tissues, and high bacterial loads. This predisposes to wound complications, especially in the setting of neoadjuvant chemoradiotherapy. Additional sacral resection further compounds these effects. We aimed to assess perineal wound outcomes and complications in patients who underwent flap reconstruction for APR with sacrectomy (APRS) at our institution. METHODS: We reviewed the charts of all patients who underwent flap reconstruction for APRS over a 20-year period (1999-2018). Medical comorbidities, details of the surgical procedure, and major and minor wound complications were recorded and analyzed. RESULTS: Forty-six patients underwent flap reconstruction following APRS-28 (60%) for colorectal cancer, 8 (17%) for sacral chordoma, and 10 diagnosed with other malignant histologies. Rectus abdominis myocutaneous (RAM) flap reconstruction was used in 42 patients (91%). The median time to the first major perineal complication was 111 days (interquartile range: 22-660 days). Half of our cohort (n = 23) experienced a major perineal complication. No significant differences were found in major or minor perineal or abdominal wall complications between RAM flap and other flaps. APR with high sacrectomy was performed in 27 patients (59%) and was associated with significantly increased full-thickness dehiscence in the perineal region when compared with APR with low sacrectomy, 33 versus 0%, respectively (p = 0.0076). Complete flap loss occurred in one patient. CONCLUSION: The RAM flap was the workhorse flap for pelvic reconstruction following APRS in our cohort. Wound complications are common following APRS. High sacrectomy is associated with higher incidence of complications compared with low sacrectomy. Optimal surgical planning and patient counseling is fundamental to improve current surgical outcomes.

Landmarks in Facial Rejuvenation Surgery: The Top 50 Most Cited Articles.

BACKGROUND: Facial rejuvenation procedures are common in plastic surgery. OBJECTIVES: The aim of this study was to report the 50 most cited articles in the field of aesthetic facial rejuvenation surgery and provide a simple educational resource for plastic surgeons. METHODS: The authors utilized the Web of Science Citation Index to identify the 50 most cited articles related to surgery for facial rejuvenation published from 1950 to 2019. Articles were classified according to their level of evidence, type of study, country of publication, and topic of interest: facelift, blepharoplasty, brow lift, neck lift, or combined areas. RESULTS: The mean number of citations per article was 137, and the majority of articles (n = 19) were published between 1990 and 1999. The most prevalent topic was facelift surgery (n = 24), followed by articles discussing combined procedures (n = 13), blepharoplasty (n = 6), brow lift (n = 4), and neck lift (n = 3). Most of the articles were classified as clinical (n = 26), followed by basic science studies (n = 12) and review articles (n = 12). Among the articles amenable to grading level of evidence (n = 26), most (n = 24) presented their findings utilizing level IV evidence. The nation of origin for most of the articles (n = 41) was the United States. CONCLUSIONS: Articles addressing facelift surgery represented the largest proportion of peer-reviewed landmark publications in aesthetic facial surgery research. A simple educational resource is presented to encourage the appreciation of the research in this field.

Profile of Adipose-Derived Stem Cells in Obese and Lean Environments.

BACKGROUND: With the demand for stem cells in regenerative medicine, new methods of isolating stem cells are highly sought. Adipose tissue is a readily available and non-controversial source of multipotent stem cells that carries a low risk for potential donors. However, elevated donor body mass index has been associated with an altered cellular microenvironment and thus has implications for stem cell efficacy in recipients. This review explored the literature on adipose-derived stem cells (ASCs) and the effect of donor obesity on cellular function. METHODS: A review of published articles on obesity and ASCs was conducted with the PubMed database and the following search terms: obesity, overweight, adipose-derived stem cells and ASCs. Two investigators screened and reviewed the relevant abstracts. RESULTS: There is agreement on reduced ASC function in response to obesity in terms of angiogenic differentiation, proliferation, migration, viability, and an altered and inflammatory transcriptome. Osteogenic differentiation and cell yield do not show reasonable agreement. Weight loss partially rescues some of the aforementioned features. CONCLUSIONS: Generally, obesity reduces ASC qualities and may have an effect on the therapeutic value of ASCs. Because weight loss and some biomolecules have been shown to rescue these qualities, further research should be conducted on methods to return obese-derived ASCs to baseline. LEVEL V: This journal requires that authors assign a level of evidence to each article.

Comparative Study of Liposomal Bupivacaine Versus Paravertebral Block for Pain Control Following Mastectomy with Immediate Tissue Expander Reconstruction.

BACKGROUND: Several approaches to minimize postoperative pain, nausea, and enhance recovery are available for patients undergoing mastectomy with immediate tissue expander (TE) reconstruction. We compared the effectiveness of intraoperative local infiltration of liposomal bupivacaine (LB) to preoperative paravertebral block (PVB). METHODS: We retrospectively reviewed patients who underwent mastectomy with immediate TE reconstruction between May 2012 and October 2014 and compared patients with preoperative ultrasound-guided PVB to those with intraoperative LB infiltration. RESULTS: Fifty-three patients (54.6 %) received LB and 44 received PVB. LB was associated with less opioid use in the recovery room (p < 0.001), fewer patients requiring antiemetics (p = 0.03), and lower day of surgery pain scores (p = 0.008). LB also was associated with longer time to first opioid use (p = 0.04). On multivariable analysis controlling for expander placement location, year of surgery, and axillary lymph node dissection (ALND), the only variable that remained statistically significant was lower opioid use in the recovery room for patients with LB (p = 0.03) and day of surgery pain scores approached significance (p = 0.05). There was no difference in the proportion of patients discharged within 36 h of surgery between the groups. Focusing on first cases of the day (where PVBs are performed in the OR) showed average time to skin incision was 15 min shorter in the LB group (p = 0.004). CONCLUSIONS: Local infiltration of LB in patients undergoing mastectomy with immediate TE reconstruction decreases narcotic requirements in the recovery room, shortens preoperative anesthesiology time, and provides similar, if not better, perioperative pain control compared with PVB.

Oncologic reconstruction of the hand and upper extremity: Maximizing functional outcomes.

Upper extremity malignancies have the potential to create significant functional impairment, and as such represent an opportunity for collaborative reconstruction to minimize potential morbidity. Given the increased complexity and array of potential reconstruction solutions, functional limb preservation is overwhelmingly and increasingly successful in appropriately selected patients. The purpose of this review is to familiarize the reader with the general functional considerations of the upper extremity, review major reconstructive options, and present a general algorithm for reconstruction and maintenance of function.

Management of ulnar nerve injuries.

Injuries to the ulnar nerve result in both sensory and motor deficits within the hand. Functional outcomes following repair of this nerve have not performed as well as outcomes following repair of the median or radial nerves. Advances in imaging modalities may provide earlier means of identifying and diagnosing closed nerve injuries. Early neurorrhaphy of acute nerve injuries provides the best outcome, but consideration should also be given to performing distal motor nerve transfers to preserve hand intrinsic motor function when injuries occur at or above the proximal forearm. This article attempts to summarize the most recent trends within ulnar nerve repair.

Functional Outcomes Following Bridge Plate Fixation for Distal Radius Fractures.

PURPOSE: To determine the functional outcomes of patients treated with dorsal spanning distraction bridge plate fixation for distal radius fractures. METHODS: All adult patients at our institution who underwent treatment of a unilateral distal radius fracture using a dorsal bridge plate from 2008 to 2012 were identified retrospectively. Patients were enrolled in clinical follow-up to assess function. Wrist range of motion, grip strength, and extension torque were measured systematically and compared with the contralateral, uninjured wrist. Patients also completed Quick-Disabilities of the Arm, Shoulder, and Hand and Patient-Rated Wrist Evaluation outcomes questionnaires. RESULTS: Eighteen of 100 eligible patients, with a minimum of 1 year from the time of implant removal, were available for follow-up (mean, 2.7 y). All fracture patterns were comminuted and intra-articular (AO 23.C3). There were significant decreases in wrist flexion (43° vs 58°), extension (46° vs 56°), and ulnar deviation (23° vs 29°) compared with the contralateral uninjured wrist. Grip strength was 86% and extension torque was 78% of the contralateral wrist. Comparison of dominant and nondominant wrist injuries identified nearly complete recovery of grip (95%) and extension (96%) strength of dominant-sided wrist injuries, compared with grip (79%) and extension (65%) strength in those with an injured nondominant wrist. Mean Quick-Disabilities of the Arm, Shoulder, and Hand and Patient-Rated Wrist Evaluation scores were 16 and 14, respectively. There were 2 cases of postoperative surgical site pain and no cases of infection, tendonitis, or tendon rupture. CONCLUSIONS: Distraction bridge plate fixation for distal radius fractures is safe with minimal complications. Functional outcomes are similar to those published for other treatment methods. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Two Decades of Insights into Nontuberculous Mycobacterial Hand Infections.

Background: The objective of our study is to describe the clinical presentation, management, and outcome of a large cohort with nontuberculous mycobacteria (NTM) hand infection. Methods: We reviewed the medical records of all adults (≥18 years) managed at the Mayo Clinic (Rochester, MN) for NTM hand infection between 1998 and 2018. Results: Our cohort included 81 patients. The median age was 61.3 (interquartile range 51.7, 69.6) years; 39.5% were immunocompromised, and 67.9% reported a triggering exposure preceding infection. Infection was deep in 64.2% and disseminated in 3.7%. Up to 16.0% received intralesional steroids because of misdiagnosis with an inflammatory process. Immunocompromised patients had deeper infection, and fewer reports of a triggering exposure. Mycobacterium marinum, Mycobacterium avium complex, and Mycobacterium chelonae/abscessus complex were the most common species. The median antibiotic duration was 6.1 (interquartile range 4.6, 9.9) months. Deep infection and infection with species other than M marinum were associated with using a greater number of antibiotics for combination therapy and an extended duration of treatment. Immunosuppression was also associated with longer courses of antibiotic therapy. Surgery was performed in 86.5% and 32.4% required multiple procedures. Ten patients, mostly with superficial infections, were treated with antibiotics alone. The 5-year cumulative rate of treatment failure was 30.3% (95% confidence interval, 20.9-44.0). Immunosuppression and intralesional steroid use were risk factors for failure. Conclusions: Treatment of NTM hand infection usually requires surgery and antibiotics, but antibiotics alone may occasionally be attempted in select cases. Immunosuppression and intralesional steroids are risk factors for treatment failure.

Most Cited Articles in Body Contouring: A Bibliometric Analysis of the Past 45 Years.

Introduction: The purpose of this study is to produce a bibliometric review of the 30 most cited articles related to 6 major domains of body contouring-abdominoplasty, thighplasty, brachioplasty, gluteoplasty, body lift, and liposuction-for resident and fellow education. Methods: The authors utilized the Web of Science Citation Index to identify the 30 most cited articles related to surgery for body contouring published from 1975 to 2020. Articles were classified according to their level of evidence, type of study, and country of publication. Results: A total of 336 articles were reviewed to compile our list. The mean number of citations across the articles was 114.7 ± SD 86.1. The highest prevalence of the papers was published between 2000 and 2009 (n = 15, 50%). The country with the highest number of contributions was the United States (n = 22, 73%). Plastic and Reconstructive Surgery served as the main journal of publication for these papers (n = 22, 73.3%). The majority of articles were designated for clinical-type studies (n = 26, 86.7%). No basic science or prevalence study design papers were listed. In terms of level of evidence (LoE), most papers were assigned IV (n = 11, 36.7%) and III (n = 7, 23.3%). Conclusions: Our study reveals that the most cited papers in body contouring are of LoE III and IV. Although the LoE of plastic surgery research, in general, has improved, in the past decade, a call for higher quality papers remains. Overall, this analysis provides an easy, electronic starting point for residents and fellows interested in understanding the field's evolution.

Surgical management of subungual melanoma: mayo clinic experience of 124 cases.

BACKGROUND: Optimal surgical management of subungual malignant melanoma (SMM) has been debated. METHODS: Our tumor registry was reviewed for surgically treated cases of SMM from 1914 to 2010. Resection levels were compared with outcome. RESULTS: During a 96-year period, 124 cases of SMM were identified (65 men and 59 women). Mean age at diagnosis was 58 years. Mean length of symptoms before diagnosis was 2.2 years. Lesions occurred on the hand (n = 79) and foot (n = 45). The thumb (33.8%) and hallux (25.0%) were affected most. At diagnosis, most had local (83.9%) and regional nodal involvement (12.9%). Mean follow-up was 9.4 years.Mean Breslow depth was 3.1 mm. Amputations were most commonly performed on the thumb at the proximal phalanx or metacarpophalangeal joint (43.9%), and on the hallux at the proximal phalanx or metatarsophalangeal joint (69.0%).Disease progression occurred in 61 (49.2%) patients, and most commonly occurred as regional nodal (62.3%) and distant metastasis (42.6%). Disease progression-free survival rates at 5, 10, and 15 years were 57.1%, 49.9%, and 47.0%, respectively. Fifty-three patients died of melanoma-related causes. Disease-specific survival rates at 5, 10, and 15 years after surgery were 59.3%, 49.3%, and 45.2%. Overall survival rates at 5, 10, and 15 years were 60.5%, 43.8%, and 33.1%.In 116 patients who underwent amputation, resection level outcome analysis with univariate and multivariate analysis adjusting for tumor depth and clinical involvement demonstrated that level of resection was not significantly associated with progression-free, overall, or disease-specific survival. CONCLUSIONS: Diagnosis of subungual melanoma is often delayed and carries a poor prognosis. Conservative resections are warranted as resection level does not influence outcome when histologically free margins are obtained. Amputation through the proximal phalanx or the metatarsophalangeal joint is required in the hallux and toes. Fingers require resection through the distal interphalangeal joint. For the thumb, although resection through the interphalangeal joint proved adequate, secondary efforts should be directed toward maximizing function and quality of life. Function-preserving resections in the thumb with nail removal, partial distal phalanx resection, and volar flap reconstruction are easily performed and preserve length, maximize joint and sensory function, and improve cosmesis.

Maximizing Solid Organ and Face Transplant Procurement Team Coordination: The Posterior Tibial Artery Flap as an Ideal Sentinel Flap.

Face transplantation became a reality with the first case performed in 2005. Facial tissue allograft procurement is technically complex and time-intensive. Brain-dead deceased donors are frequently, if not always, multiorgan donors. Every effort should be made during face allograft recovery to minimize any risk to the recovery of lifesaving solid organs. Some programs require the procurement of a myofascial vascularized skin graft to function as a sentinel flap allowing frequent monitoring for rejection without negatively impacting the esthetics of the face graft. Up till now, the flap used has been the radial forearm flap. Procuring the radial forearm flap places the procuring team in close proximity to the head and torso, where the face recovery and the solid organ recovery teams would require unhindered access. Here, we present the posterior tibial artery flap as an alternative flap that would provide benefits to the coordination of the multiple teams working to procure organs from a deceased donor.
