IntroductionThere are many suitable techniques for the treatment of soft tissue defects of the lower limb. Older subjects often with multiple comorbidities, presenting with a laterally located and complex defect, can be challenging to treat. This cohort are often unsuited to long procedures or multi-stage reconstruction and so one is faced with a paucity of options. In such instances, we use the peroneus brevis (PB) muscle flap as a single stage procedure.MethodsWe performed a retrospective study evaluating the use of PB flaps in lower limb injury. Subjects were collated using a database and multiple variables were assessed including: patient demographics, comorbidities, defect size, peri-operative timings, time in theatre, use of inotropes / blood transfusion, mean hospital stay, patient morbidity / mortality, flap survival.ResultsDuring 2015-2023, 49 patients underwent lower limb reconstruction using PB muscle flaps. 42 cases involved PB and skin graft alone whilst seven were more complex requiring additional local and free tissue techniques. The most common indication (n = 28) was infection after closed fracture fixation, followed by open trauma (n = 21). Median patient age was 59 (20-93 years), and ASA grade 3. Median defect size was 4 × 7 cm (2-18 cm) and time from admission to definitive closure 4 days (0-21 days) with median time in theatre 120 min (45-520 min). 17 patients required inotropes and 13 had blood transfusion. Median length of hospital stay was 12 days (0-58 days), one patient (aged 90) died. 100 % of flaps survived and median Enneking score was 65. Heterotopic ossification was not identified in the post-operative imaging within the first year.DiscussionOur experience highlights the benefits and risks of using the PB flap and advocates it as a reliable, cost-effective, 1-stage technique for reconstructing small lateral defects in the distal third of the lower limb.Copyright © 2024 Elsevier Ltd.
