Tackling bone loss of the lower extremity: vascularized bone grafting

Post-traumatic lower extremity bone loss in the setting of high-energy trauma can occur acutely as a result of an open fracture and surgical debridement, or secondarily as a result of nonunion or infection. Several techniques have been described in the literature for the management of these bony defects, including non-vascularized bone grafts, vascularized bone grafts and distraction osteogenesis. Herein, the authors review the role of vascularized bone grafts in the management of post-traumatic bone loss in the lower extremity

A Bipedicled Flap for Closure of the Anterolateral Thigh Flap Donor Site.

Anterolateral thigh (ALT) free flaps have become reliable options for head-to-toe reconstruction. Although perforator anatomy is fairly predictable, in cases of eccentric perforator location, we proposed shifting the entire flap laterally and preserving a medial bipedicled flap between the original incision and the new medial flap margin. This facilitates primary donor site closure instead of harvesting a flap larger than anticipated. We conducted a retrospective chart review of ALT flaps performed between 2007 and 2019 and identified patients who underwent bipedicled closure of the donor site. Demographics, flap characteristics, and surgical technique were evaluated. Six patients had bipedicled donor site closure related to primary perforators located lateral to the original flap design. The mean defect size was 91 cm2, and bipedicled flap width ranged from 4 to 6 cm. All donor sites were closed primarily. Five of the donor thigh sites healed without complications, and 1 patient had superficial delayed healing of the medial bipedicled incision, which healed with local wound care. The ALT has become an invaluable flap in microsurgical reconstruction, yet it is not without limitations. Primary donor site closure is generally not feasible for larger flaps, thus necessitating skin grafting of the donor site and/or prolonged wound care. Our technique facilitates primary closure of the donor site in patients who otherwise would have required harvest of a larger than necessary flap based on eccentric perforator anatomy. The medial bipedicled flap is straightforward, reproducible, and allows for modifications of the original flap design to better fit the defect

Current status of simulation training in plastic surgery residency programs: A review

Increased emphasis on competency-based learning modules and widespread departure from traditional models of Halstedian apprenticeship have made surgical simulation an increasingly appealing component of medical education. Surgical simulators are available in numerous modalities, including virtual, synthetic, animal, and non-living models. The ideal surgical simulator would facilitate the acquisition and refinement of surgical skills prior to clinical application, by mimicking the size, color, texture, recoil, and environment of the operating room. Simulation training has proven helpful for advancing specific surgical skills and techniques, aiding in early and late resident learning curves. In this review, the current applications and potential benefits of incorporating simulation-based surgical training into residency curriculum are explored in depth, specifically in the context of plastic surgery. Despite the prevalence of simulation-based training models, there is a paucity of research on integration into resident programs. Current curriculums emphasize the ability to identify anatomical landmarks and procedural steps through virtual simulation. Although transfer of these skills to the operating room is promising, careful attention must be paid to mastery versus memorization. In the authors’ opinions, curriculums should involve step-wise employment of diverse models in different stages of training to assess milestones. To date, the simulation of tactile experience that is reminiscent of real-time clinical scenarios remains challenging, and a sophisticated model has yet to be established

Case-matched Comparison of Implant-based Breast Reconstruction with and without Acellular Dermal Matrix

Background:. Acellular dermal matrix (ADM) is commonly used in implant-based breast reconstruction due to improved soft-tissue support and control of the implant pocket and decreased capsular contracture. However, concerns about complications have prompted the FDA to request more clinical data. This large-scale study aims to examine perioperative outcomes of ADM use in breast reconstruction. Methods:. This study utilized a national insurance-based database to identify patients who underwent mastectomy between 2011 and 2019, with and without ADM. The groups were matched for age, region, and comorbidities. Complications within 90 days were compared using univariate and multivariate analyses. Results:. A total of 49,366 patients were identified with 26,266 patients in the ADM group and 23,100 in the non-ADM group. Infection rates (4.7% ADM versus 4.4% no ADM) and seroma rates (3.9% ADM versus 4% no ADM) were similar. However, the ADM group had a 1% higher rate of implant removal (4.9% ADM versus 3.9% no ADM, P < 0.001). In direct-to-implant procedures, ADM use was associated with higher explantation rates (8.2% versus 6.3%, P = 0.002). Multivariate analysis identified tobacco use, hypertension, depression, obesity, ADM usage, and direct-to-implant surgery as risk factors for implant removal. Conclusions:. This study found comparable infection and seroma rates in implant-based breast reconstruction with and without ADM. ADM use was associated with a 1% higher risk of implant removal, with risk factors including tobacco use, obesity, hypertension, depression, and direct-to-implant procedures. Multicenter studies and registry data on prepectoral breast reconstruction are warranted to help interpret these findings

Attributes of Perforator Flaps for Prophylatic Soft Tissue Augmentation Prior to Definitive Total Knee Arthroplasty.

BACKGROUND:  As our population ages, the demand for total knee arthroplasty (TKA) will dramatically increase to ensure an independent lifestyle with unimpeded and pain-free ambulation. Complications will be inevitable, especially in that patient with preexisting soft tissue deficits or extensive scarring in the knee region. Under these circumstances, prophylactic soft tissue augmentation should be strongly considered and be extremely beneficial. METHODS:  A retrospective review of all TKA procedures at our institutions over the past two decades revealed seven patients who specifically had soft tissue augmentation prior to their definitive TKA. Each had a single perforator flap used to achieve this. In no cases was a muscle flap used for this purpose. Excluded were all patients who had a flap of any kind for coverage of an exposed prosthesis or to accomplish wound healing after the TKA. RESULTS:  Seven perforator flaps were utilized in seven patients for soft tissue replacement prior to the ultimate TKA. For smaller defects in three patients, a local island medial sural artery perforator flap was used. For larger defects in four patients, an anterolateral thigh perforator free flap was necessary. All flaps were successful. The only complication was an implant infection after one anterolateral thigh free flap that required a revision arthroplasty that eventually allowed salvage. Unrestricted ambulation was possible in all patients except for one who had a preexisting contralateral below-knee amputation. CONCLUSION:  As the number of TKA procedures in the near future increases, prevention of the absolute number of complications becomes even more important. An awareness that any knee region suboptimal soft tissue base can lead to wound breakdown and then periprosthetic infection should alert all involved that prevention of this sequela can be best achieved by prior soft tissue augmentation. Preferably, this may be possible by capturing the assets of local and free perforator flaps

Fasciocutaneous flap reinforcement of ventral onlay buccal mucosa grafts enables neophallus revision urethroplasty

Background: Urethral strictures or fistulas are common complications after phalloplasty. Neourethral defects pose a difficult reconstructive challenge using standard techniques as there is generally insufficient ventral tissue to support a graft urethroplasty. We report our experience with local fasciocutaneous flaps for support of ventrally-placed buccal mucosal grafts (BMGs) in phalloplasty. Methods: A retrospective review of patients who underwent phalloplasty and subsequently required revision urethroplasty using BMGs between 2011 and 2015 was completed. Techniques, complications, additional procedures, and outcomes were examined. Results: A total of three patients previously underwent phalloplasty with sensate radial forearm free flaps (RFFFs): two female-to-male (FTM) gender reassignment, and one oncologic penectomy. Mean age at revision urethroplasty was 41 years (range 31–47). Indications for surgery were: one meatal stenosis, four urethral strictures (mean length 3.6 ± 2.9 cm), and two urethrocutaneous fistulas. The urethral anastomosis at the base of the neophallus was the predominant location for complications: 3/4 strictures, and 2/2 fistulas. Medial thigh (2) or scrotal (1) fasciocutaneous flaps were used to support the BMG for urethroplasty. One stricture recurrence at 3 years required single-stage ventral BMG urethroplasty supported by a gracilis musculocutaneous flap. All patients were able to void from standing at mean follow up of 8.7 months (range 6–13). A total of two patients (66%) subsequently had successful placement of a penile prosthesis. Conclusions: Our early results indicate that local or regional fasciocutaneous flaps enable ventral placement of BMGs for revision urethroplasty after phalloplasty
