Background:  The timing of free flap reconstruction after lower extremity trauma has been a controversial debate since Marko Godina's original 72-hour recommendation. Recent advances in microsurgery warrant an evaluation of the optimal time to reconstruction., Methods:  The Nationwide Readmission Database (2014-2019) was used to identify patients undergoing free flap reconstruction after lower extremity trauma. Risk-adjusted statistical methods were used to identify optimal time where risk of infectious and microsurgical complications increase and to quantify the risk associated with time delays., Results:  A total of 1,030 patients undergoing reconstruction were identified. The mean time to flap coverage was 24.3 days. Thirty-three percent were performed within 72 hours, 24% from 72 hours to 10 days, 18% from 10 to 30 days, and 24% after 30 days. Flaps performed after 10 days were associated with increased risk of surgical site infection, osteomyelitis, and other wound complications, compared with those performed within 72 hours. There was no increased risk in the period of 72 hours to 10 days. Revision amputation and microsurgical complications were not increased after 10 days. The predicted optimal cutoff was 9.5 days for microsurgical complications and 14.5 days for infectious complications., Conclusion:  Advances in microsurgery may be responsible for extending the time in which definitive soft tissue coverage is required for wounds resulting from lower extremity trauma. Although it appears the original 72-hour time window can be safely extended, efforts should be made to refer patients to specialty limb salvage centers in a timely fashion., Competing Interests: Disclosure The authors report no conflicts of interest in this work., (Thieme.

Background: A recent analysis of microsurgery fellowship match data published in 2019 demonstrated increased competition for available positions. With growing opportunities in the field, the authors hypothesize that the landscape for both applicants and programs has become more competitive. The aim of this study is to compare two periods of match data to inform residents and programs in microsurgery., Methods: Microsurgery fellowship match data was obtained from the San Francisco Match with approval by the American Society for Reconstructive Microsurgery for the years 2014-2022. Data were stratified into the categories of 2016-2018 and 2019-2022. Parameters assessed included: program and position fill rates, match rates, and in-service examination percentiles. Data were analyzed using Pearson's Chi-square tests and unpaired t-tests., Results: The median number of participating programs and positions increased to 29 and 47 in 2019-2022, compared with 23 and 40 in 2016-2018. This coincided with a decrease in the number of applicants per position (1.3 [52-40] vs. 1.1 [50-47], p = .45). There was a significant increase in the match rate between groups (67.8% vs. 80.2%, p = .007). Recently, 2022 saw the lowest position fill rate on record, at 75.4% (40 of 53 positions filled), down from 85.3% (35 of 41) in 2018 (p = .35) and 95.6% (43 of 45) in 2019 (p = .006). Mean in-service examination percentiles for successfully matched applicants did not differ between (2016-2018) and (2019-2022) applicants., Conclusion: Recent years have seen a rise in the number of microsurgery fellowship training programs with a decline in the number of applicants. Accordingly, there has been an increased match rate for prospective applicants. Despite this, a pool of unmatched applicants and unfilled positions with training opportunities still remain. The reasons for which are likely multifactorial., (© 2024 Wiley Periodicals LLC.)

Background and Objective: Large defects of the nose after Mohs surgery pose a significant reconstructive challenge to both dermatologic and reconstructive surgeons. The authors present their 12-year experience utilizing acellular dermal matrices for nasal reconstruction., Methods: A retrospective review of patients undergoing Mohs surgery and alloplastic nasal reconstruction with acellular dermal matrices between 2010 and 2022 was performed. Patients who underwent single-stage reconstruction and dual-stage reconstruction with skin graft with at least 90 days of follow-up were included., Results: Fifty-one patients met criteria with a median age of 77 years. Fifty-three lesions were reconstructed with acellular dermal matrices. The most common lesion location was nasal sidewall (50%) with a mean defect size of 10.8 cm 2 . 30.8% underwent same-day acellular dermal matrix reconstruction, with 69.2% undergoing two-stage reconstruction. Acellular dermal matrices successfully reconstructed acquired defects in 94.2% of lesions. Average time to re-epithelialization was 27.6 + 6.2 days. Average time to repigmentation was 145.35 + 86 days. No recurrences were recorded. Total complication rate was 9.62%. Average size for successful healing was 10.8 cm 2 . Average defect size for complication or failure was 14.7 cm 2 . Seven sites (13.46%) underwent aesthetic improvement procedures., Conclusion: Acellular bilayer wound matrix is an adequate reconstructive option for single or dual-stage reconstruction of the nose with low complication and revision rates., (Copyright © 2024 by the American Society for Dermatologic Surgery, Inc.

Background: Although intraperitoneal and retromuscular mesh placement in ventral hernia repair (VHR) are associated with lower recurrence rates, the onlay plane remains a well-established option for certain clinical scenarios. A knowledge gap remains regarding resorbable biosynthetic onlay mesh and mesh exposure. We aim to determine exposure rate, risk factors, and treatment options., Study Design: A single-center, two-surgeon retrospective review was performed examining patients who underwent VHR with onlay, Poly-4-hydroxybutyrate (P4HB) mesh from 2015 to 2021. Demographics, operative characteristics, outcomes, and mesh exposure management were analyzed., Results: Of 346 patients, 15 (4.3%) experienced mesh exposure. The mean age was 53 years and BMI of 33.6 kg/m 2 . Patients were majority ASA class 3 (65%), female (64.2%), and averaged a defect size of 307.9 ± 235.2 cm 2 . Independent risk factors included diabetes (AOR = 4.3,CI 1.5-12.5;p < 0.005) and COPD (AOR = 5.2,CI 1.3-21.8;p = 0.02). Mesh exposures were identified as outpatient (20%) or intraoperative (80%). All underwent operative debridement, in which nine were managed with skin reclosure, two with partial closure, and four healed by secondary intention. Five patients required excision of unincorporated mesh. Four patients required further debridement from chronic surgical site occurrences; however, all mesh exposure patents healed after a mean of 260.8 ± 313.2 days and retained original mesh. The recurrence rate was 6.7% for mesh exposure patients., Conclusion: When faced with mesh exposure, resorbable biosynthetic mesh placed in onlay fashion was retained in all patients. Patients with a history of diabetes or COPD have increased risk of mesh exposure and should be counseled., (© 2024.

Background: A previous study by the authors noted a decline in independent plastic surgery residency programs and rising applicant participation. This study provides updates on match trends and influential predictors, and gathers program leaders' views on the future of the independent track., Methods: Match data (2019-2022) were obtained from the San Francisco match after American Council of Educators in Plastic Surgery approval. Variables influencing match success were analyzed, and program leaders were surveyed about desirable applicant traits and program trajectories., Results: From 2019 to 2022, 243 of 428 applicants matched. Programs and positions declined by 10% and 9.5%, respectively. Applicants rose to 42.3%, but match rates fell from 82% to 56%. Osteopathic graduates doubled, whereas international graduates increased to 53.8%. Successful matches were associated with US allopathic medical school graduates, university-affiliated general surgery residencies, eight or more interviews, United States Medical Licensing Examination scores greater than 230, and high post graduate year (PGY)1-3 American Board of Surgery In-service Training Examination scores (PGY1-64.7%, PGY2-61.2%, PGY3-60.7%; P < 0.05). Of surveyed programs, 55.6% aimed to continue running the independent track in the next year. Conversely, 7.4% planned to discontinue in the next year, 22.2% within 2-5 years, 7.4% within the next decade, and 7.4% were unsure., Conclusions: Although support for the independent plastic surgery track remains, program participation diminishes as applicant interest increases, intensifying match challenges. Increasing number of interviews improves match potential. Program leaders display varied commitments, with looming plans for some programs to discontinue offering this track. Applicant evaluation pivots on strong recommendations, research, and test scores., Competing Interests: Jeffrey Janis receives royalties from Thieme and Springer publishing and is a co-founder of the Plastic Surgery Central Application.

Background: Split-thickness skin grafts (STSGs) remain a valuable tool in the reconstructive surgeons' armamentarium. Staple or suture mechanical fixation (MF) serves as the gold standard of care, though fibrin glue (FG) has gained popularity as a fixation modality. We compare STSG outcomes following application of FG versus MF through a study of lower extremity wounds. Methods: A retrospective review (2016-2019) of patients who underwent a STSG was performed. Two cohorts consisting of patients undergoing a STSG with FG or MF (suture or staple) were matched according to wound size, wound location, and body mass index. Results: A total of 67 patients with 79 wounds were included (FG: n = 30, wounds = 39; MF: n = 37; wounds = 40). There was no significant difference between groups regarding time to 100% graft take (FG: 39 days, MF: 35.1 days; P  < .384) or 180-day graft complications (FG: 10.3%, MF: 15%; P  < .737). Adjusted operative time for FG (51.8 min) was lower than for MF cases (67.5 min) at a level that approached significance ( P  < .094). FG patients were significantly less likely to require a postoperative wound vacuum-assisted closure (VAC) (FG: 16.7%; MF: 76.7%; P  < .001) and required a significantly lower number of 30-day postoperative visits (FG: 1.5 ± .78 visits; MF: 2.5 ± .03 visits; P  < .001). The MF group had higher mean aggregate charges ($211,090) compared with the FG group (mean: $149,907), although these were not statistically significant ( P  > .05). Conclusion: The use of FG for STSG shows comparable clinical outcomes to MF, with a significantly decreased need for postoperative wound VAC, the number of 30-day postoperative visits, and a lower wound-adjusted operative time., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: John P.

Introduction: Mohs surgery and reconstruction has enabled tissue-preserving resection of cutaneous malignancies. The goal of our case series evaluation is to present reconstructive techniques and functional outcomes in patients undergoing digit-sparing treatment for primary melanoma., Materials and Methods: A chart review was performed to identify consecutive patients undergoing Mohs surgery and reconstruction for melanoma of the digits. Quality of life (QOL) survey was performed to assess function after the procedure., Results: Thirty-two patients (13 hand, 19 foot, Age: 65.03 +/-17.78 years) who were undergoing Mohs surgery were identified. No recurrence was identified with an average follow-up of 16.1 months (1-95 months). The average defect size was 5.79 +/-4.54 cm 2 . Reconstruction was performed 0-4 days after resection. The most common techniques included full-thickness skin graft (FTSG) ( N = 7), collagen matrix + FTSG ( N = 4), and volar advancement flap ( N = 7). The reconstructive technique choice appears correlated with defect size ( p = 0.0125). Neuro-QOL upper extremity survey results showed a difference that approached statistical significance between patients who underwent digit-sparing treatment ( n = 7) versus direct to amputation controls ( n = 5) ( p = 0.072). No survey differences between digit-sparing treatment ( n = 10) and amputation ( n = 8) were identified in the lower extremity ( p = 0.61)., Conclusion: Our results show digit-sparing treatment can confirm clear surgical margins and a trend toward improvement in upper extremity function compared with immediate amputation., Competing Interests: None declared., (© 2024 Published by Elsevier B.V. on behalf of Society for Indian Hand Surgery and Micro Surgeons.)

Background: Design freedom offered by additive manufacturing allows for the implementation of functional gradients - where mechanical stiffness is decreased along the length of the implant. It is unclear if such changes will influence failure mechanisms in the context of rib fracture repair. We hypothesized that our novel functionally graded rib implants would be less stiff than controls and decrease occurrence of secondary fracture at implant ends., Methods: Five novel additively manufactured rib implants were tested along with a clinically used Control implant. Fracture reconstructions were modeled with custom synthetic rib bones with a transverse B1 fracture. Ribs were compressed in a cyclic two-point bend test for 360,000 cycles followed by a ramp to failure test. Differences in cyclic stiffness, 3D interfragmentary motions, ramp-to-failure stiffness, maximum load, and work to failure were determined., Findings: The Control group had lower construct stiffness (0.76 ± 0.28 N/mm), compared to all novel implant designs (means: 1.35-1.61 N/mm, p < 0.05) and rotated significantly more about the bending axis (2.7° ± 1.3°) than the additively manufactured groups (means between 1.2° - 1.6°, p < 0.05). All constructs failed via bone fracture at the most posterior screw hole. Experimental implants were stiffer than Controls, and there were few significant differences between functional gradient groups., Interpretation: Additively manufactured, functionally graded designs have the potential to change the form and function of trauma implants. Here, the impact of functional gradients was limited because implants had small cross-sectional areas., Competing Interests: Declaration of Competing Interest None., (Copyright © 2023.

Background: We aimed to identify how Integra bilayer wound matrix has expanded facial reconstruction options after Mohs surgery due to its reliability in both single- and dual-stage reconstruction., Methods: A retrospective review of patients undergoing Mohs surgery and alloplastic facial reconstruction with Integra between 2012 and 2022 was performed. Patients who underwent single-stage reconstruction and dual-stage reconstruction with skin graft with at least 90 days of follow-up were included., Results: One hundred thirty patients with a median age of 76 years were included. Basal cell carcinoma was the most common malignancy (39%). One hundred forty-two lesions were treated and reconstructed same-day with Integra. Lesions most commonly involved the nose (34%) and forehead (22%). The mean postoperative defect size was 26.9 cm 2 . An estimated 45.5% (n = 60) of defect sites underwent single-stage reconstruction with healing by secondary intention, whereas 54.5% (n = 72) underwent dual-stage reconstruction with skin graft. Integra success rate was 90.2%. Average time to re-epithelialization was 32.2 + 7.3 days. Average time to repigmentation was 169.5 + 14.6 days. The complication rate was 12.8% (n = 17), with 12 undergoing debridement, three needing new Integra graft, and seven needing new skin grafts. Average size for successful healing without complication was 26.6 cm 2 . Nineteen sites (13.2%) underwent aesthetic improvement procedures, with the majority occurring after dual-stage reconstruction (n = 13)., Conclusions: Integra is a reliable outpatient reconstructive option for facial Mohs defects that can increase the threshold for autologous tissue harvesting and successfully reconstruct large defects of 26.6 cm 2 on average with low complication and reoperation rates., Competing Interests: Dr. Kovach has received consultant payments from Becton Dickinson and Integra Life Sciences.

Humanitarian crises create opportunities for both in-person and remote aid. Durable, complex, and team-based care may leverage a telemedicine approach for comprehensive support within a conflict zone. Barriers and enablers are detailed, as is the need for mission expansion due to initial program success. Adapting a telemedicine program initially designed for critical care during the severe acute respiratory syndrome coronavirus 2 pandemic offers a solution to data transfer and data analysis issues. Staffing efforts and grouped elements of patient care detail the kinds of remote aid that are achievable. A multiprofessional team-based approach (clinical, administrative, nongovernmental organization, government) can provide comprehensive consultation addressing surgical planning, critical care management, infection and infection control management, and patient transfer for complex care. Operational and network security create parallel concerns relevant to avoid geolocation and network intrusion during consultation. Deliberate approaches to address cultural differences that influence relational dynamics are also essential for mission success., Competing Interests: Dr. Kaplan is a Past-President of the Society of Critical Care Medicine (2020–2021) and an editorial board member of Critical Care Medicine.

Background: Breast implant illness (BII) is a poorly understood heterogeneous disorder treated with implant removal; however, patient-reported symptoms and outcomes after treatment remain unclear., Methods: A retrospective review of patients undergoing bilateral breast implant removal related to BII by two surgeons at an academic medical center between 2018 and 2022 was conducted. Patients were surveyed using the BREAST-Q Reconstruction model with the American Society for Aesthetic Plastic Surgery BII survey extension. Outcomes were analyzed using multivariable logistic regression, adjusted for patient-associated factors., Results: Forty-seven patients were surveyed with a response rate of 51% (n = 24). Of the 20 patients who completed the survey, the majority were White (85%), with 45% (n = 9) having a documented history of psychiatric illness. Six (30%) patients had capsular contracture and four (20%) had documented implant rupture. Most implant removal procedures (n = 12, 60%) were not covered by insurance. Fourteen (70%) patients reported a net improvement in their symptoms after implant removal, most commonly chest discomfort, muscle pain, fever, and headaches. Capsular contracture was predictive of reduced psychosocial, sexual, and breast satisfaction scores ( P = 0.015). Self-pay was predictive of increased breast satisfaction scores ( P = 0.009), but had no impact on symptomatic improvement. A reduced time to implant removal was predictive of fewer residual symptoms ( P = 0.032). Psychiatric illness had no significant impact on the outcomes., Conclusions: In the setting of suspected or diagnosed BII, a reduced time to implant removal may decrease the risk of residual symptoms and improve overall patient satisfaction. In patients with capsular contracture, preoperative counseling should emphasize that implant removal may only improve physical symptoms., Competing Interests: The authors have no financial interest to declare in relation to the content of this article., (Copyright © 2023 The Authors.

Background: Poly-4-hydroxybutyrate (P4HB) (Phasix) biosynthetic mesh was recently introduced as an alternative to synthetic and biologic meshes for ventral hernia repair (VHR). However, outcomes data are limited. This study aims to analyze outcomes of VHR with P4HB mesh and identify predictors of postoperative outcomes., Methods: We performed a retrospective study of adults who underwent open VHR with P4HB by the senior author from 2014 to 2020 with >12 months' follow-up. Subgroup comparisons and multivariate logistic regression were performed., Results: Inclusion criteria were met by 169 patients with a median of 15 months of follow-up. Overall, 21.9% had surgical site occurrences, 17.8% required reoperation, and 4.7% had recurrences. Patients with prior VHR (47.9%) experienced similar outcomes to those without. Patients with prior mesh infection (18.3%) had higher rates of postoperative mesh infection (6.5% vs 0.7%; P = .029) but did not have higher rates of reoperation. Retrorectus repairs (45.5%) had similar outcomes to onlay repairs (54.5%). Recurrence risk was increased by hypertension (odds ratio [OR] = 13.64; P = .046), immunosuppression (OR = 42.57; P = .004), and history of prior VHR (OR = 20.20; P = .014)., Conclusions: This study aimed to analyze outcomes of VHR augmented with P4HB mesh through retrospective review. VHR with P4HB mesh produces acceptable recurrence rates with favorable complication risks compared with biologic and synthetic meshes. Predictors of recurrence include a history of prior hernia repair, hypertension, and immunosuppression. A history of prior mesh infection seems to place patients at risk for developing subsequent infection but did not increase need for reoperation., (© 2023 HMP Global. All Rights Reserved.

Background: Conventional excision of female genital skin cancers has high rates of local recurrence and morbidity. Few publications describe local recurrence rates (LRRs) and patient-reported outcomes (PROs) after Mohs micrographic surgery (MMS) for female genital skin cancers., Objective: To evaluate LRRs, PROs, and interdisciplinary care after MMS for female genital skin cancers., Methods: A retrospective case series was conducted of female genital skin cancers treated with MMS between 2006 and 2021 at an academic center. The primary outcome was local recurrence. Secondary outcomes were PROs and details of interdisciplinary care., Results: Sixty skin cancers in 57 patients were treated with MMS. Common diagnoses included squamous cell cancer (n = 26), basal cell cancer (n = 12), and extramammary Paget disease (n = 11). Three local recurrences were detected with a mean follow-up of 61.1 months (median: 48.8 months). Thirty-one patients completed the PROs survey. Most patients were satisfied with MMS (71.0%, 22/31) and reported no urinary incontinence (93.5%, 29/31). Eight patients were sexually active at follow-up and 75.0% (6/8) experienced no sexual dysfunction. Most cases involved interdisciplinary collaboration 71.7% (43/60)., Limitations: Limitations include the retrospective single-center design, heterogeneous cohort, and lack of preoperative function data., Conclusions: Incorporating MMS into interdisciplinary teams may help achieve low LRRs and satisfactory function after genital skin cancer surgery., Competing Interests: Conflicts of interest None disclosed., (Copyright © 2023 American Academy of Dermatology, Inc.

Background: New treatments for recalcitrant chylous ascites are needed to avoid sequelae associated with increased intraabdominal pressures, chyle loss, and diminished quality of life. An autologous microsurgical technique was developed to treat recalcitrant chylous ascites and restore normal physiology., Methods: A retrospective case series was performed for patients with recalcitrant chylous ascites surgically treated from 2018 to 2020. The authors included all patients with recalcitrant chylous ascites refractory to current standard-of-care interventions such as diet modifications, pharmacologic therapies, and peritoneovenous mechanical shunts. All were treated with microsurgical peritoneovenous bypass with a minimum follow-up of 12 months., Results: Six patients were included over a 2-year period. Surgery was aborted for two patients (33%) with intraoperative venous reflux of the deep inferior epigastric vein, negative on preoperative ultrasound. One patient had a successful reoperation using the contralateral greater saphenous vein; the other elected for a chronic indwelling drain for chyle drainage. Among the five successful procedures (83%), ascites drainage decreased from a median preoperative volume of 1 L/day to postoperative volume of 0.06 L/day. Median hospital length of stay was 7 days (range, 212 to 194 days). Three patients had one complication each, including vancomycin-resistant Enterococcus , spontaneous bacterial peritonitis, and pulmonary embolism. All complications resolved with additional interventions. Median follow-up was 13.5 months (range, 12 to 27 months)., Conclusion: Microsurgical peritoneovenous bypass was a reliable and reproducible autologous surgery for the treatment of recalcitrant chylous ascites at a minimum follow-up of 12 months., Clinical Question/level of Evidence: Therapeutic, IV., (Copyright © 2023 by the American Society of Plastic Surgeons.)

Purpose: Reconstruction of massive incisional hernias (IHs) poses a significant challenge with high rates of recurrence. Preoperative chemodenervation using botulinum toxin (BTX) injections in the abdominal wall is a technique that has been used to facilitate primary fascial closure. However, there is limited data directly comparing primary fascial closure rates and postoperative outcomes after hernia repair between patients who do and do not receive preoperative BTX injections. The objective of our study was to compare the outcomes of patients who did and did not receive BTX injections before abdominal wall reconstruction., Methods: This is a retrospective cohort study including adult patients from 2019 to 2021 who underwent IH repair with and without preoperative BTX injections. Propensity score matching was performed based on body mass index, age, and intraoperative defect size. Demographic and clinical data were recorded and compared. The statistical significance level was set at P < 0.05., Results: Twenty patients underwent IH repair with preoperative BTX injections. Twenty patients who underwent IH repair without preoperative BTX injections were selected to comprise a 1:1 propensity-matched control cohort. The average defect size was 663.9 cm2 in the BTX group and 640.7 cm2 in the non-BTX group (P = 0.816). There was no difference in average age (58.6 vs 59.2 years, P = 0.911) and body mass index (33.0 vs 33.2 kg/m2, P = 0.911). However, there was a greater proportion of male patients in the BTX group (85% vs 55%, P = 0.082).Primary fascial closure was achieved in 95% of BTX patients and 90% of non-BTX patients (P = 1.0). Significantly fewer patients in the BTX group required component separation techniques to achieve primary fascial closure (65% vs 95%, P = 0.044). There was no significant difference in any postoperative surgical and medical outcomes. Hernia recurrence was 10% in the BTX group and 20% in non-BTX group (P = 0.661)., Conclusions: In our study, we observed a lower rate of component separations to achieve primary fascial closure among patients with massive hernia defects who received preoperative BTX injections. These results suggest that preoperative BTX injections may "downstage" the complexity of hernia repair with abdominal wall reconstruction in patients with massive hernia defects and reduce the need for component separation., Competing Interests: Conflicts of interest and sources of funding: none declared., (Copyright © 2023 Wolters Kluwer Health, Inc.

This study aimed to analyze the association between completion of research training and career success in American plastic surgery faculty to aid trainees in their decisions to perform research fellowships., Methods: A cross-sectional analysis of attending academic plastic surgeons in the United States was conducted. Outcomes were compared between faculty who completed research training (research fellowship, PhD, or MPH) and those who did not. Outcomes included promotion to full professor and/or department chair, h-index, and attainment of National Institutes of Health funding. Outcomes were analyzed using chi-squared tests, t tests, and multivariable regressions., Results: A total of 949 plastic surgery faculty members were included, and of those, 185 (19.5%) completed dedicated research training, including 13.7% (n = 130) who completed a research fellowship. Surgeons who completed dedicated research training were significantly more likely to achieve full professorship (31.4% versus 24.1%, P = 0.01), obtain National Institutes of Health funding (18.4% versus 6.5%, P < 0.001), and have a higher mean h-index (15.6 versus 11.6, P < 0.001). Dedicated research fellowships were independently predictive of achieving full professorship (OR = 2.12, P = 0.002), increased h-index (β = 4.86, P < 0.001), and attainment of National Institutes of Health funding (OR = 5.06, P = 0.01). Completion of dedicated research training did not predict an increased likelihood of becoming department chair., Conclusion: The performance of dedicated research training was predictive of improved markers of career success in plastic surgery and should be considered beneficial in both the short and long term., Competing Interests: The authors have no financial interest to declare in relation to the content of this article., (Copyright © 2023 The Authors.

Prospective, multicenter, single-arm study of antimicrobial-coated, noncrosslinked, acellular porcine dermal matrix (AC-PDM) in a cohort involving all centers for disease control and prevention wound classes in ventral/incisional midline hernia repair (VIHR)., Materials and Methods: Seventy-five patients (mean age 58.6±12.7 years; BMI 31.3±4.9 kg/m 2 ) underwent ventral/incisional midline hernia repair with AC-PDM. Surgical site occurrence (SSO) was assessed in the first 45 days post-implantation. Length of stay, return to work, hernia recurrence, reoperation, quality of life, and SSO were assessed at 1, 3, 6, 12, 18, and 24 months., Results: 14.7% of patients experienced SSO requiring intervention within 45 days post-implantation, and 20.0% thereafter (>45 d post-implantation). Recurrence (5.8%), definitely device-related adverse events (4.0%), and reoperation (10.7%) were low at 24 months; all quality-of-life indicators were significantly improved compared to baseline., Conclusion: AC-PDM exhibited favourable results, including infrequent hernia recurrence and definitely device-related adverse events, with reoperation and SSO comparable to other studies, and significantly improved quality of life., Competing Interests: All conflicts of interest have been declared in the Author Disclosure Form uploaded with this submission and are listed below in a de-identified list without author names to preserve anonymity.

The medial femoral condyle free flap serves as an attractive reconstructive option for small- to intermediate-sized bony defects. It is commonly applied in the extremities with limited reports in the head and neck., Methods: A systematic review of the literature was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines., Results: Seventeen articles met inclusion criteria, yielding 166 cases for analysis, with a majority of the cohort from a single study (n = 107; 64.4%). However, all included studies represented novel reconstructive sites and surgical indications. Flap components were described in 157 cases; periosteum was used only in four cases (2.5%), whereas all others are composed of cortical bone combined with periosteum, cancellous bone, and/or cartilage (97.5%). Additionally, a skin island was used in 43 cases (25.9%). Flap measurements were reported in 51 cases, averaging 4.5 ± 2.7 cm in length. Seven cases listed skin island dimensions, averaging 20.2 ± 12.8 cm 2 . The descending genicular artery was the primary pedicle employed (n = 162; 97.6%), while the superior medial genicular was used in the descending genicular artery's absence (n = 4; 2.4%). Descending genicular artery pedicle length from 15 reporting cases averaged 6.4 ± 1.2 cm. Successful reconstructions totaled 160 cases (96.4%). Recipient complications were seen in 16 cases (9.6%) with six constituting flap failures (3.6%). Donor site complications were minimal (n = 6; 3.6%); however, this included one major complication of femoral shaft fracture., Conclusion: The medial femoral condyle free flap is an effective reconstructive option for the head and neck due to its versatile nature, low complication profile at both recipient and donor site, ease of harvest, and two-team approach., Competing Interests: Shaun D. Mendenhall is an educational consultant for PolyNovo, which is unrelated to this study.

Amputations have been performed with few modifications since the dawn of surgery. Blood vessels are ligated, bones are shortened, and nerves are cut. In a percentage of people, this can result in severe neuropathic, residual limb, and phantom limb pain. Targeted muscle reinnervation is a surgical procedure initially conceived to optimize function for myoelectric prostheses in amputees. Recently, it has been adopted more widely by surgeons for the prevention and treatment of neuropathic pain. Perhaps as a function of its relatively recent development, many authors perform this operation differently, and there has been no overall agreement regarding the principles, indications, technical specifics, and postoperative management guidelines. This article is written as a consensus statement by surgeons focused on the treatment of neuropathic pain and those with extensive experience performing targeted muscle reinnervation. It is designed to serve as a roadmap and template for extremity surgeons to consider when performing targeted muscle reinnervation., Competing Interests: Dr. Eberlin is consultant for AxoGen, Integra, Checkpoint.

Background: Vascularized fibula epiphyseal flap was first described in 1998 for proximal humeral reconstruction in children/infants. The authors aim to review their international, multi-institutional, long-term outcomes., Methods: An international, multi-institutional review (2004 to 2020) was conducted of patients younger than 18 years undergoing free vascularized fibula epiphyseal transfer for proximal humeral reconstruction. Donor- and recipient-site complications, pain, and final ambulatory status were reviewed. Growth of the transferred bone was assessed under the guidance of a pediatric musculoskeletal radiologist., Results: Twenty-seven patients were included with a median age of 7 years (range, 2 to 13 years). Average follow-up was 120 ± 87.4 months. There were two flap failures (7.4%). Recipient-site complications included fracture [ n = 11 (40.7%)], avascular necrosis of the fibula head [ n = 1 (3.7%)], fibular head avulsion [ n = 1 (3.7%)], infection [ n = 1 (3.7%)], and hardware failure [ n = 1 (3.7%)]. Operative fixation was necessary in one patient with a fracture. The case of infection necessitated fibula explantation 2 years postoperatively, and ultimately, prosthetic reconstruction. Sixteen patients developed peroneal nerve palsy (59.3%): 13 of these cases resolved within 1 year (81% recovery), and three were permanent (11.1%). One patient (3.7%) complained of upper extremity pain. Longitudinal growth was confirmed in all but three cases [ n = 24 (88.9%)] at an average rate of 0.83 ± 0.25 cm/year., Conclusions: The vascularized fibula epiphysis for proximal humerus reconstruction in children preserves the potential for future growth and an articular surface for motion. Peroneal nerve palsy is common following harvest, although this is often transient. Future efforts should be geared toward reducing postoperative morbidity., Clinical Question/level of Evidence: Therapeutic, IV., Competing Interests: Disclosure:The authors declare no financial or other conflicts of interest pertinent to this study., (Copyright © 2022 by the American Society of Plastic Surgeons.)

Learning Objectives: After studying this article, the participant should be able to: 1. Have an in-depth understanding of the functional and aesthetic requirements of lower extremity reconstruction. 2. Describe the considerations for achieving an optimal aesthetic outcome in the primary reconstruction settings. 3. Describe modalities of secondary flap revision for achieving an optimal aesthetic outcome., Summary: Significant advancements have been made in the management of lower extremity reconstruction since Dr. Taylor's seminal case in 1973. Improvements in our understanding of vascular anatomy and evolution of microsurgical techniques have allowed for an ever-increasing array of free tissue transfer options for lower extremity reconstruction. The resulting expertise has engendered a paradigm shift toward the reconstructive elevator approach, with increased emphasis on cosmetic results. In the primary setting, aesthetic considerations play an important role in precoverage wound preparation, flap selection, and harvest technique, with the goal of achieving excellent like-with-like reconstruction at the time of initial surgery. Flap selection should be made to best match the three-dimensional architecture of the wound, and take into account the defect thickness, flap thickness, flap composition, and pedicle length. Primary flap thinning and harvest in the superficial fascial plane has been shown to be an effective modality to address excess adiposity and improve contour. Despite these efforts, secondary procedures are often required to optimize the limb's final appearance and functional outcomes, particularly in the foot and ankle region. These include debulking, liposuction, and staged excisions. As the field of limb salvage keeps evolving, aesthetics will continue to play an important role in extremity reconstruction planning and execution., Competing Interests: Disclosure: The authors have no financial interests or conflicts of interest to declare in relation to the content of this article., (Copyright © 2023 by the American Society of Plastic Surgeons.)

Background: Despite advanced wound care techniques, open fractures in the setting of lower extremity trauma remain a challenging pathology, particularly when free tissue transfer is required for coverage. We aimed to evaluate factors associated with flap failure in this setting using a large, heterogeneous patient population., Methods: Retrospective review of patients who underwent traumatic lower extremity free flap reconstruction (2002-2019). Demographics wound/vessel injury characteristics, pre and perioperative factors, and flap outcomes were analyzed., Results: One hundred eighty-eight free flaps met inclusion criteria, with 23 partial (12.2%) and 13 total (6.9%) flap failures. Angiography was performed in 87 patients, with arterial injury suffered in 43.1% of those evaluated. Time to flap coverage varied within 3 days (4.5%), 10 days (17.3%), or 30 days of injury (42.7%). In all, 41 (21.8%) subjects suffered from major flap complications, including failure and takebacks. Multivariate regression demonstrated the presence of posterior tibial (PT) artery injury predictive of both flap-failure (Odds ratio [OR] = 11.4, p < .015) and major flap complications (OR = 12.1, p < .012). Immunocompromised status was also predictive of flap failure (OR = 12.6, p < .004) and major complications (OR = 11.6, p < .007), while achieving flap coverage within 30 days was protective against flap complications (OR = 0.413, p < .049). Defect size, infection, and injury location were not associated with failure., Conclusions: When examining a large, heterogeneous patient cohort, free flap outcomes in the setting of lower extremity open fractures can be influenced by multiple factors. This presence of PT artery injury, flap coverage beyond 30 days of injury, and immunocompromised status appear predictive of flap complications in this context., (© 2021 Wiley Periodicals LLC.)

Background: Total ankle arthroplasty (TAA) is a popular modality to treat end-stage arthritis or internal ankle derangement. Unfortunately, failure rates remain undesirably high, with severe complications, including prosthesis failure, ankle fusion, and amputation. The importance of a stable soft-tissue envelope for coverage of implant compromise has been previously described, but the predictive factors for successful salvage of complicated TAA remain poorly understood., Methods: A retrospective review was conducted of patients requiring soft-tissue reconstruction following TAA wound complications. Patient demographics, history, microbiological data, reconstructive approach, and outcomes data were collected. Statistical analysis was used to abstract factors associated with unsuccessful prosthetic salvage., Results: In all, 13 patients met inclusion criteria: 8 (61.5%) achieved prosthetic salvage, and 5 (38.5%) failed. The majority (90.9%) of patients presented with infected joints. Reconstructive techniques included skin grafts, dermal substitutes, locoregional flaps, and free tissue transfer. Successful prosthetic salvage was associated with shorter time intervals between wound diagnosis and index reconstructive surgical intervention (median: 20 days for salvage vs 804 days for failure; P = .014). Additionally, salvage was associated with reduced time from the index orthopaedic/podiatric surgical intervention to the index reconstructive surgery procedure (12 vs 727 days; P = .027)., Conclusion: The prognosis of complicated TAA requiring soft-tissue reconstruction remains poor, especially in patients who present with infected joints. Several reconstructive techniques, ranging from simple skin grafts to complex free tissue transfers, can be used successfully. Early intervention to achieve soft-tissue coverage is crucial in maximizing salvage rates in the setting of complicated and infected TAA., Level of Evidence: Level IV.

Background: Targeted muscle reinnervation has emerged as a technique to reduce neuroma and phantom limb pain after below-knee amputation; however, the incidence of postoperative complications remains unknown. This multi-institutional study assessed the risk of postoperative complications among patients who underwent targeted muscle reinnervation at the time of below-knee amputation., Methods: Patients who underwent below-knee amputation with targeted muscle reinnervation were propensity score-matched 1:3 to patients who underwent below-knee amputation alone. Study outcomes included the incidence of major or minor complications within 60 days. Regression models were used to estimate the relative risk of major and minor complications., Results: Overall, 96 patients were matched, including 31 patients who had below-knee amputation with targeted muscle reinnervation and 65 who had below-knee amputation alone. In the matched sample, a higher incidence of major complications (29 percent versus 24.6 percent), readmission (25.8 percent versus 18.5 percent), and reoperation (19.4 percent versus 10.8 percent) was seen after both procedures compared with below-knee amputation alone. Patients who underwent both procedures displayed a higher incidence of minor complications (25.8 percent versus 20.0 percent), blood transfusion (22.6 percent versus 18.5 percent), and wound healing complications (45.2 percent versus 33.8 percent) and longer operative time (mean ± SD, 188.5 ± 63.6 minutes versus 88 ± 28.2 minutes). There was no statistically significant difference in the risk of major (relative risk, 1.20; 90 percent CI, 0.68, 2.11) or minor (relative risk, 1.21; 90 percent CI, 0.61, 2.41) complications between the two cohorts., Conclusions: Despite an increased incidence of postoperative complications, undergoing below-knee amputation with targeted muscle reinnervation does not confer a statistically significant increased risk of major or minor complications. Future studies are needed to delineate patient selection criteria when assessing the suitability of targeted muscle reinnervation at the time of major limb amputation., Clinical Question/level of Evidence: Therapeutic, III., (Copyright © 2022 by the American Society of Plastic Surgeons.)

Background: When traditional V-Y advancement flaps cannot span cutaneous defects, the modified Pacman™ V-Y advancement flap (Pacman™ VYAF) design increases its utility for challenging facial defects., Objective: To describe the usage and surgical outcomes of Mohs micrographic surgery (MMS) defects repaired with the Pacman™ VYAF., Methods: A retrospective review was performed on MMS defects repaired with the Pacman™ VYAF in the division of dermatologic surgery at a large academic institution between January 01, 2013 and August 01, 2019., Results: Twenty-nine instances of Pacman™ VYAF reconstructions were identified. Reconstruction of the cheek (22/29, 76%) was the most common, followed by the temple (4/29, 14%), and the post-auricular neck (3/29, 10%). Distal flap necrosis occurred more frequently in large Pacman™ VYAF repairs (6/29, 21% of cases), requiring surgical revision in 1 case. Surgical scars from the Pacman™ VYAF are rated favorably by dermatologic surgeons., Conclusion: The Pacman™ VYAF is a useful reconstruction option for surgical defects of the head and neck, and it is advantageous compared to traditional V-Y advancement flaps for defects with length greater than width., Competing Interests: Declaration of Competing Interest Conflict of interest: none.

The senior author first coined the "orthoplastic" approach to traumatic lower extremity reconstruction, by which multidisciplinary surgeons and specialists work together for optimal patient success. The goals of lower extremity salvage are to optimize limb appearance, restore unrestricted pain-free ambulation, and improve quality of life. Composite traumatic defects require an organized approach, and the reconstructive ladder is used for strategies of varying complexity for repair of soft-tissue wounds. The lower rungs of the ladder include simpler reconstructive options such as the use of skin grafts and local flaps, and the higher rungs represent complex techniques such as free tissue transfer. Although there is no notable difference between muscle and fasciocutaneous/perforator flaps in reconstructive outcomes, there has been a trend toward perforator flaps to minimize donor site morbidity., (Copyright © 2022 by the American Academy of Orthopaedic Surgeons.)

Background: Women undergoing immediate breast reconstruction without radiation therapy have reconstruction methods available with uncertain long-term costs associated with complications requiring surgery and revisions. We evaluated cost-effectiveness of nine methods of immediate breast reconstruction for women with localized breast cancer., Methods: Markov modeling was performed over 10-years for unilateral/bilateral breast reconstructions from healthcare/societal perspectives. PubMed, Embase, Cochrane, Scopus, and CINAHL were searched to derive data from 13,744 patients in 79 prospective studies. Complications requiring surgery (mastectomy necrosis, total/partial flap necrosis, seroma, hematoma, infection, wound dehiscence, abdominal hernia, implant removal/explantation) and revisions (fat necrosis, capsular contracture, asymmetry, scars/redundant tissue, implant rupture/removal, fat grafting) were evaluated over yearly cycles. Reconstructions included: direct-to-implant (DTI), tissue expander-to-implant (TEI), latissimus dorsi flap-to-implant (LDI), latissimus dorsi (LD), pedicled transverse rectus abdominis myocutaneous (TRAM), free TRAM, deep inferior epigastric perforator/superficial inferior epigastric artery (DIEP/SIEA), thigh-based, or gluteal based flaps. Outcomes were incremental cost-effectiveness ratios (ICER) and net monetary benefits (NMB). Willingness-to-pay thresholds were $50,000 and $100,000., Results: From a healthcare perspective for unilateral reconstruction, compared to LD, the ICER for DTI was -$42,109.35/quality-adjusted life-years (QALY), LDI was -$25,300.83/QALY, TEI was -$22,036.02/QALY, DIEP/SIEA was $8307.65/QALY, free TRAM was $8677.26/QALY, pedicled TRAM was $13,021.44/QALY, gluteal-based was $17,698.99/QALY, and thigh-based was $23,447.82/QALY. NMB of DIEP/SIEA was $404,523.47, free TRAM was $403,821.40, gluteal-based was $392,478.64, thigh-based was $387,691.70, pedicled TRAM was $376,901.83, LD was $370,646.93, DTI was $339,668.77, LDI was $334,350.30, and TEI was $329,265.84., Conclusions: All nine methods of immediate breast reconstruction were considered cost-effective from healthcare/societal perspectives. LD provided the lowest costs, while DIEP/SIEA provided the greatest effectiveness and NMB., (© 2022 Wiley Periodicals LLC.)

Background: Abdominal wall reconstruction persists as a challenging surgical issue with a multitude of management strategies available. The aim of this study was to examine the efficacy of resorbable synthetic mesh onlay plane against biologic mesh in the intraperitoneal plane., Methods: A single-center, two-surgeon, 5-year retrospective review (2014 to 2019) was performed examining subjects who underwent abdominal wall reconstruction in the onlay plane with resorbable synthetic mesh or in the intraperitoneal plane with biologic mesh. A matched paired analysis was conducted. Data examining demographic characteristics, intraoperative variables, postoperative outcomes, and costs were analyzed., Results: Eighty-eight subjects (44 per group) were identified (median follow-up, 24.5 months). The mean age was 57.7 years, with a mean body mass index of 30.4 kg/m2. The average defect size was 292 ± 237 cm2, with most wounds being clean-contaminated (48.9 percent) and 55 percent having failed prior repair. Resorbable synthetic mesh onlay subjects were significantly less likely (4.5 percent) to experience recurrence compared to biologic intraperitoneal mesh subjects (22.7 percent; p < 0.026). In addition, mesh onlay suffered fewer postoperative surgical-site occurrences (18.2 percent versus 40.9 percent; p < 0.019) and required fewer procedural interventions (11.4 percent versus 36.4 percent; p < 0.011), and was also associated with significantly lower total costs ($16,658 ± $14,930) compared to biologic intraperitoneal mesh ($27,645 ± $16,864; p < 0.001)., Conclusions: Abdominal wall reconstruction remains an evolving field, with various techniques available for treatment. When faced with hernia repair, resorbable synthetic mesh in the onlay plane may be preferable to biologic mesh placed in the intraperitoneal plane because of lower long-term recurrence rates, surgical-site complications, and costs., Clinical Question/level of Evidence: Therapeutic, III., (Copyright © 2022 by the American Society of Plastic Surgeons.)

Background: We evaluated metrics between academic plastic surgeons that were and were not presidents of national organizations to determine predictors of becoming a president., Methods: A cross-sectional retrospective review was performed. Websites were queried of 99 Accreditation Council for Graduate Medical Education accredited plastic surgery residency programs and 17 national organizations. Demographic, academic and scholarly variables we collected from 951 full-time plastic surgery faculty affiliated with the US residency training programs during the 2020-2021 academic year. Of these full-time plastic surgery faculty, 879 were non-presidents and 72 were presidents of national organizations (2016-2021 = 42, < 2016 = 30)., Results: Plastic surgeons were more likely to become president if they were an officer/director of the American Board of Plastic Surgeons (ABPS) (OR: 16.67, 95%CI: 5.83, 47.66; p < 0.001), chief/chair of a division/department (OR: 3.10, 95%CI: 1.09, 8.79; p = 0.033), endowed (OR: 5.45, 95%CI:1.65, 18.04; p = 0.006), National Institutes of Health (NIH) funded (OR: 4.57, 95%CI: 1.24, 16.88; p = 0.023), affiliated with an integrated plastic surgery residency program (OR: 3.96, 95%CI: 1.27, 12.33; p = 0.018), and with a greater number of years in practice (OR: 1.09, 95%CI: 1.04, 1.14; p < 0.001). Additionally, plastic surgeons were more likely to become president between 2016 and 2021 with a research fellowship (OR: 7.41, 95%CI: 1.02, 52.63; p = 0.047), first author publications (OR: 1.72, 95%CI: 1.63, 1.83; p < 0.001), and last author publications (OR: 1.60, 95%CI: 1.56, 1.65; p  < 0.001)., Conclusions: Plastic surgeons were more likely to become president of a national organization if they were an officer/director of the ABPS, chief/chair of a division/department, endowed, NIH funded, affiliated with an integrated plastic surgery residency program, greater number of years in practice, research fellowship, and first and last author publications.

Background: We reviewed the individual participant data of patients who sustained isolated common peroneal nerve (CPN) injuries resulting in foot drop. Functional results were compared between eight interventions for CPN palsies to determine step-wise treatment approaches for the underlying mechanisms of nerve injury., Methods: PubMed, Embase, Cochrane Library, Web of Science, Scopus, and CINAHL databases were searched. PRISMA-IPD and Cochrane guidelines were followed in the data search. Eligible patients sustained isolated CPN injuries resulting in their foot drop. Patients were stratified by mechanisms of nerve injury, ages, duration of motor symptoms, and nerve defect/zone of injury sizes, and were compared by functional results (poor = 0, fair = 1, good = 2, excellent = 3), using meta-regression between interventions. Interventions evaluated were primary neurorrhaphy, neurolysis, nerve grafts, partial nerve transfer, neuromusculotendinous transfer, tendon transfer, ankle-foot orthosis (AFO), and arthrodesis., Results: One hundred and forty-four studies included 1284 patients published from 1985 through 2020. Transection/Cut: Excellent functional results following tendon transfer (OR: 126, 95%CI: 6.9, 2279.7, p=0.001), compared to AFO. Rupture/Avulsion: Excellent functional results following tendon transfer (OR: 73985359, 95%CI: 73985359, 73985359, p<0.001), nerve graft (OR: 4465917, 95%CI: 1288542, 15478276, p<0.001), and neuromusculotendinous transfer (OR: 42277348, 95%CI: 3001397, 595514030, p<0.001), compared to AFO. Traction/Stretch: Good functional results following tendon transfer (OR: 4.1, 95%CI: 1.17, 14.38, p=0.028), compared to AFO. Entrapment: Excellent functional results following neurolysis (OR: 4.6, 95%CI: 1.3, 16.6, p=0.019), compared to AFO., Conclusions: Functional results may be optimized for treatments by the mechanism of nerve injury. Transection/Cut and Traction/Stretch had the best functional results following tendon transfer. Rupture/Avulsion had the best functional results following tendon transfer, nerve graft, or neuromusculotendinous transfer. Entrapment had the best functional results following neurolysis., Competing Interests: Declaration of Competing Interest None., (Copyright © 2021 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Background: Local tissue rearrangement, free flap reconstruction, and Bilayer Wound Matrix represent reconstructive modalities for coverage of scalp defects; however, preferred indications are less clear. The authors aimed to evaluate the efficacy of these interventions., Methods: A retrospective review (2008 to 2019) was performed of subjects requiring soft-tissue reconstruction of oncologic scalp wounds. Subjects were dual matched into two comparative cohorts: (1) local tissue rearrangement versus Bilayer Wound Matrix, and (2) free flap reconstruction versus Bilayer Wound Matrix. Ninety-day wound coverage, hospital length of stay, operative time, and wound complications were compared., Results: In total, 361 subjects were included. Following matching, 126 subjects constituted the local tissue rearrangement versus Bilayer Wound Matrix cohort, and 56 constituted the free flap reconstruction versus Bilayer Wound Matrix cohort. Local tissue rearrangement/Bilayer Wound Matrix median defect size was 35 ± 42.5 cm2. Local tissue rearrangement provided significantly better wound coverage at 90 days (95.2 percent) compared to Bilayer Wound Matrix (84.1 percent) (p < 0.040). Median defect size in the free flap reconstruction/Bilayer Wound Matrix cohort was 100 ± 101.1 cm2. Ninety-day success (free flap reconstruction, 92.9 percent; Bilayer Wound Matrix, 96.4 percent; p < 1.00) and reoperation rates (14.3 percent versus 3.6 percent; p < 0.352) were similar. However, free flap reconstruction had significantly greater operative times (418 minutes versus 100 minutes; p < 0.001)., Conclusions: Local tissue rearrangement may be more reliable for smaller wounds (<100 cm2) compared to Bilayer Wound Matrix. Bilayer Wound Matrix may have comparable efficacy to free flap reconstruction for larger defects (150 to 250 cm2), and may be more cost-effective, given greater operative time and length of stay associated with free flap reconstruction., Clinical Question/level of Evidence: Therapeutic, III., (Copyright © 2021 by the American Society of Plastic Surgeons.)

Objective: To describe evidenced-based treatment options for patients who sustained trauma and/or posttraumatic osteomyelitis of the tibia resulting in diaphyseal bone defects and to compare outcomes between patients treated with nonvascularized bone grafts (NBGs), bone transport (BT), or vascularized bone grafts (VBGs)., Data Source: The Preferred Reporting Items for Systematic Review and Meta-Analyses of individual participant data and Cochrane guidelines were followed. PubMed, EMBASE, Cochrane Library, Web of Science, Scopus, and CINAHL were searched from inception to June 2020., Study Selection: Patients who were ≥18 years, had sustained trauma to the tibia resulting in fracture and/or osteomyelitis with measurable diaphyseal bone defects, and were treated by interventions such as NBGs, BT, or VBGs were eligible. Excluded studies were non-English, reviews, nonreviewed literature, cadavers, animals, unavailable full texts, nondiaphyseal defects, atrophic nonunions, malignancy, and replantations., Data Extraction: A total of 108 studies were included with 826 patients.

Summary: Patients with significant loss of abdominal wall soft tissue represent a reconstructive challenge. The purpose of this study was to describe the authors' experience using microvascular free tissue transfer to repair complex abdominal wall defects with insufficient overlying soft tissue. In this report, the authors highlight their techniques and experiences in performing microvascular free tissue transfer to the abdominal wall for these massive, complex defects. In total, 14 patients who underwent 16 free-flap reconstructions were included in the series. The patients' mean age was 50 ± 14 years, and mean body mass index was 27 ± 5 kg/m2. The mean hernia defect size was 412 ± 149 cm2. Ten flaps were fasciocutaneous anterolateral thigh flaps, one myocutaneous anterolateral thigh flap, two subtotal thigh flaps, one myocutaneous latissimus dorsi flap, one parascapular/latissimus dorsi flap, and one free filet of the lower leg. Five cases (36 percent) developed hernia recurrence, and seven developed surgical site complications. All flaps survived, with no total flap loss. This report highlights that microsurgical free tissue transfer in combination with mesh repair is a safe and reliable method for restoring complex, large, full-thickness abdominal wall defects. This case series illustrates a number of techniques and considerations that are of importance to achieve a favorable outcome when faced with these complex defects., Clinical Question/level of Evidence: Therapeutic, IV., (Copyright © 2021 by the American Society of Plastic Surgeons.)

Background Androgenetic alopecia (AGA) is the most common cause of hair loss in men. In this study, we evaluated the cost-effectiveness of minoxidil monotherapy, minoxidil and platelet-rich plasma (PRP) combined therapy, and PRP monotherapy for the long-term treatment of early-onset AGA Hamilton-Norwood stages I-V in men. Methodology Markov modeling was performed to analyze the base-case parameters from 18 level I/II studies. The model base-case assumes a healthy 25-year-old man presenting to a dermatologist or plastic surgeon's office as a new patient for the evaluation and treatment of AGA Hamilton-Norwood stages I-V (non-severe AGA in men). Simulations began at an age of 25 years and ran over 35 years. Analyses were conducted from healthcare and societal perspectives. Outcomes included incremental cost-effectiveness ratios (ICER) and net monetary benefits (NMB). Willingness-to-pay (WTP) thresholds were set at $50,000 and $100,000. Deterministic and probabilistic sensitivity analyses were performed to evaluate uncertainty over 10,000 simulations. Results From a healthcare perspective, compared to minoxidil monotherapy, the ICER for minoxidil+PRP was $52,036/quality-adjusted-life-year (QALY) and the ICER for PRP monotherapy was $439,303/QALY. The NMB of minoxidil monotherapy was $914,887, minoxidil+PRP was $914,350, and PRP monotherapy was $904,572 at a WTP threshold of $50,000. When the WTP threshold was increased to $100,000, the NMB of minoxidil+PRP was $1,843,908, minoxidil monotherapy was $1,831,237, and PRP monotherapy was $1,822,246. Societal trends were similar. Conclusions Minoxidil 5% topical twice-daily monotherapy provided cost-effective treatment for men with AGA Hamilton-Norwood stages I-V at a WTP threshold of $50,000, whereas combining minoxidil 5% with PRP provided cost-effective treatment at a WTP threshold of $100,000.

Purpose: To compare two cohorts of patients; those with isolated ventral hernias (VH) and those with VH and enterocutaneous fistulas (ECF). Risk factors for surgical complications (including recurrent ECF) and outcomes during single-stage VH with ECF surgical reconstruction were analyzed., Methods: A retrospective review was performed from 2008 to 2019. We compared two cohorts of patients with single-stage VH repairs: (1) ventral hernia repair alone (hernia alone), and (2) combined VH repair and ECF repair (hernia plus ECF). Inclusion criteria were patients ≥ 18 years of age with pre-operative VH either with or without an ECF, who underwent open hernia repair and ECF repair in a single-stage operation, with a minimum follow-up of 12 months. Patient risk factors, operative characteristics, outcomes and surgical-site complications were compared using univariate and multivariate analyses., Results: We included 442 patients (hernia alone = 401; hernia plus ECF = 41) with a median follow-up of 22 months (12-96). Hernia plus ECF patients were more likely to have inflammatory bowel disease (IBD)(OR 4.4, 95% CI 1.1-17.5, p = 0.037), a history of abdominal wound infections (OR 3.4, 95% CI 1.5-7.9, p = 0.004), reoperations (OR 4.9, 95% CI 1.6-15.4, p = 0.006), superficial soft tissue infections (OR 2.5, 95% CI 1.1-6.1, p = 0.044) and hematomas (OR 8.4, 95% CI 1.2-58.8, p = 0.031), compared to hernia alone patients. ECF recurrence was associated with diabetes mellitus (DM) (n = 8, 73% vs. n = 6, 20%; p = 0.003) and surgical-site complications (n = 10, 91% vs. n = 16, 53%; p = 0.048), compared to ECF resolution., Conclusion: Risk factors for developing ECF were IBD and history of abdominal wound infections. Single-staged combined ECF reconstruction was associated with reoperations, soft tissue infections and hematomas. DM and surgical-site complications were associated with ECF recurrence., (© 2021.

Background: Scalp wounds pose reconstructive challenges due to the lack of skin elasticity, potential for compromised adjacent tissue, and desire for the restoration of esthetic contour. Bilayer Wound Matrix (BWM) has been successfully employed as a treatment modality for complex, full-thickness wounds of the scalp. We aimed to highlight risk factors for BWM success and failure in complex wounds of the scalp., Methods: A retrospective case-control study was performed from 2012 to 2019 of adult subjects who presented to plastic or dermatological surgery with complex scalp defects with or without exposed calvarium, who underwent staged reconstruction with BWM and split-thickness skin grafting or secondary intention. Success was defined as complete wound re-epithelialization within 90-day follow-up without additional operative procedures for wound coverage. Demographics, comorbidities, treatment history, wound characteristics, and clinical course were analyzed and correlated with reconstructive outcomes., Results: In total, 127 subjects were identified for inclusion, with mean age 74.6 ± 12.2 years, defect area 80.2 ± 89.4 cm 2 , and wound age 10.0 ± 65.4 days. Successful wound reconstruction occurred in 107 (84%) subjects. Postoperative wound infections were an independent predictor of BWM failure at 90 days (Odds Ratio: 6.4, 95% Confidence Interval: 1.5 - 26.7, and p<0.012). Additionally, subjects who underwent preoperative radiation were more likely to suffer from reconstructive failure (p<0.040) as well as those who require postoperative inpatient admission (p<0.034)., Conclusion: BWM represents a reliable and efficacious modality in the treatment of complex scalp wounds. Patient comorbidities may not heavily influence the success of BWM to establish adequate wound coverage; however, preoperative radiation and postoperative wound infection may often lead to reconstructive failure., (Copyright © 2021 Elsevier Ltd.

Thoracic duct occlusion can lead to devastating complications, resulting in recalcitrant chylothoraces, ascites, generalized lymphedema, metabolic derangement, and death. Lymphatic extravasation has traditionally been managed conservatively and, in recent years, using minimally invasive techniques, such as thoracic duct ligation and embolization. However, these measures are often limited in application and therapeutic success, resulting in chronically difficult conditions with few modalities available for definitive management. Advances in microsurgery have allowed for surgical treatment and resolution of peripherally-based lymphatic pathology, though microsurgical intervention to address central lymphatic abnormalities is scarcely described. This report is the first series detailing experiences utilizing microsurgical thoracic duct lymphovenous bypass in a refractory adult population with thoracic duct occlusion. Four patients successfully underwent the procedure, with three achieving complete resolution of symptoms. The fourth patient enjoyed partial resolution, though ubiquitous lymphatic deformities have conferred recurrent residual lower-extremity peripheral edema requiring future intervention. Postoperatively, patent anastomoses were confirmed under magnetic resonance lymphangiography. This series demonstrates the feasibility of microsurgical thoracic duct lymphovenous bypass as a promising technique in treating patients suffering from thoracic duct occlusion. This intervention is effective for recalcitrant chylothorax, chylous ascites, and generalized lymphedema, particularly when traditional and interventional radiological techniques are unsuccessful., Competing Interests: Disclosure: The authors have no financial interest in relation to the content of this article., (Copyright © 2021 The Authors.

Background: Previous studies have demonstrated that nonwhite race and disadvantaged socioeconomic status negatively impact outcomes following lower extremity reconstruction. The authors sought to characterize differences in outcomes between racial groups in patients necessitating traumatic lower extremity reconstruction at an orthoplastic limb salvage center., Methods: A retrospective review between 2002 and 2019 was conducted of patients who underwent free flap lower extremity reconstruction at an orthoplastic limb salvage center. Patient demographics were identified, and permanent addresses were used to collect census data. Short-term complications and long-term functional status were recorded., Results: One hundred seventy-three patients underwent lower extremity reconstruction and met inclusion criteria. Among all three groups, African American patients were more likely to be single (80 percent African American versus 49 percent Caucasian and 29.4 percent other; p < 0.05) and had significantly lower rates of private insurance compared with Caucasian patients (25 percent versus 56.7 percent; p < 0.05). African American patients demonstrated no significant differences in total flap failure (4.9 percent versus 8 percent and 5.6 percent; p = 0.794), reoperations (10 percent versus 5.8 percent and 16.7 percent; p = 0.259), and number of readmissions (2.4 versus 2.0 and 2.1; p = 0.624). Chronic pain management (53.3 percent versus 44.2 percent and 50 percent; p = 0.82), full weight-bearing status (84.2 percent versus 92.7 percent and 100 percent; p = 0.507), and ambulation status (92.7 percent versus 100 percent and 100 percent; p = 0.352) were similar among groups., Conclusions: Outcomes are equivalent between racial groups presenting to an orthoplastic limb salvage center for lower extremity reconstruction. The postoperative rehabilitation strategies, follow-up, and overall support that an orthoplastic limb salvage center ensures may lessen the impact of socioeconomic disparities in traumatic lower extremity reconstruction., Clinical Question/level of Evidence: Risk, II., (Copyright © 2021 by the American Society of Plastic Surgeons.)
