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.

BackgroundComplex hindfoot pathology may benefit from vascularized bone flap reconstruction rather than traditional bone grafting techniques. Medial femoral condyle (MFC) flaps provide vascularized periosteum, skin, and corticocancellous bone.MethodsA retrospective, single-institution cohort study of consecutive MFC flaps performed for complicated hindfoot reconstruction between 2013 and 2019 was reviewed. Radiologic follow-up assessed osseous union and clinical outcomes were evaluated with the American Orthopaedic Foot & Ankle Society (AOFAS) hindfoot score. Thirty MFC flaps were performed in 28 patients for complex hindfoot pathology. Twenty-seven flaps had adequate clinical and radiographic follow-up (mean 15.8 months).ResultsThe majority presented with avascular necrosis (83%) and failed prior operations (67%, mean 3.1). Most hindfoot procedures involved arthrodesis (n = 24, 80%); tibiotalocalcaneal (n = 11) and talonavicular (n = 7) most frequently. Mean osseous flap volume was 10.3 cm3 (range 1.7-18.4 cm3); one flap required takeback for venous congestion but no total flap losses occurred. Primary osseous union was initially achieved in 20 patients (74%, mean 217 days). Six flaps developed interface nonunion; 5 underwent revision arthrodesis and ultimately achieved union in 24/27 flaps (89%, mean 271 days). Risk factors for nonunion were body mass index (BMI) >30 (P = .017) and prior arthrodesis (P = .042). Mean AOFAS hindfoot scores increased significantly from 52.3 preoperatively to 70.7 postoperatively (P < .001). Subscore analysis demonstrated significant improvement in postoperative pain scores from 14.2 to 27.3 out of 40 (P < .001).ConclusionThe MFC free flap provided vascularized bone for complicated foot and ankle reconstruction with relatively low donor site morbidity, promising osseous union results, and improved functional outcomes.Level of evidenceLevel IV, retrospective case series.

Objective: Pressure injuries (PIs) often develop in critically ill patients due to immobility, and underlying comorbidities that decrease tissue perfusion and wound healing capacity. This study sought to provide epidemiological data on determinants and current managements practices of PI in patients with COVID-19. Method: A US national insurance-based database consisting of patients with coronavirus or COVID-19 diagnoses was used for data collection. Patients were filtered by International Classification of Diseases (ICD) codes corresponding to coronavirus or COVID-19 diagnosis between 2019–2020. Diagnosis of PI following COVID-19 diagnosis was queried. Demographic data and comorbidity information was compared. Logistic regression analysis was used to determine predictors for both PI development and likelihood of operative debridement. Results: A total of 1,477,851 patients with COVID-19 were identified. Of these, 15,613 (1.06%) subsequently developed a PI, and 8074 (51.7%) of these patients had an intensive care unit (ICU) admission. The average and median time between diagnosis of COVID-19 and PI was 39.4 and 26 days, respectively. PI was more likely to occur in patients with COVID-19 with: diabetes (odds ratio (OR): 1.39, 95% confidence interval (CI): 1.29–1.49; p<0.001); coronary artery disease (OR: 1.11, 95% CI: 1.04-1.18, p=0.002), hypertension (OR: 1.43, 95% CI: 1.26–1.64; p<0.001); chronic kidney disease (OR: 1.18, 95% CI: 1.10–1.26; p<0.001); depression (OR: 1.45, 95% CI 1.36–1.54; p<0.001); and long-term non-steroidal anti-inflammatory drug use (OR: 1.21, 95% CI: 1.05–1.40; p=0.007). They were also more likely in critically ill patients admitted to the ICU (OR: 1.40, 95% CI: 1.31–1.48; p<0.001); and patients requiring vasopressors (OR:1.25, 95% CI: 1.13–1.38; p<0.001), intubation (OR: 1.21, 95% CI 1.07–1.39; p=0.004), or with a diagnosis of sepsis (OR: 2.38, 95% CI 2.22–2.55; p<0.001). ICU admission, sepsis, buttock and lower back PI along with increasing Charlson Comorbidity Index (CCI) (OR: 1.04, 95% CI 1.00–1.08; p=0.043) was associated with surgical debridement. The vast majority of patients with COVID-19 did not undergo operative debridement or wound coverage. Conclusion: PIs are widely prevalent in patients with COVID-19, especially in those who are critically ill, yet the vast majority do not undergo operative procedures. Declaration of interest: The authors have no conflicts of interest to declare. [ABSTRACT FROM AUTHOR]
