ObjectiveChallenges persist in the reconstruction of the ankle and the foot with exposed tendons, joints, and bones as a result of severe burns and trauma. In flap elevation involving the sensitive superficial nerve, the local nerve was always sacrificed to obtain an anesthetic donor site; however, such a procedure introduced the possibility of painful neuromas. In this study, we present a desired clinical application of a modified reversed superficial peroneal artery flap, in which the superficial peroneal nerve is preserved.MethodsFrom 2008 to 2015, 12 patients with ankle or foot defects were treated with the modified reversed superficial peroneal artery flap. The defects of the patients were caused by hot liquid scald (one patient), electrical injury (five patients), and trauma (six patients). The flap was utilized for covering defects on the ankle (seven patients) and the foot (five patients). The size of the flaps ranged from 4.0cm×6.0cm to 18.0cm×10.0cm. The superficial peroneal artery was involved in the flap, whereas the superficial peroneal nerve was spared by dedicate dissection. The reverse-flow flap was nourished by the superficial peroneal artery through the terminal peroneal artery perforator.ResultsThe obtained outcomes were satisfactory functionally and aesthetically. The flaps in 11 patients survived completely without complications, whereas partial necrosis occurred in a 78-year-old patient when the flap survived a week later during follow up. CT angiography revealed the stenosis of the popliteal artery. The wound healed after interventional treatment involving placing a stent and changing the dressings. Basic functions and configurations were salvaged in all cases. All patients were completely satisfied with the proposed flap and suffered no paresthesia in their lower leg.ConclusionExhibiting beneficial characteristics such as reliable blood supply, favorable thickness, wide rotating arc, and retention of major vessels and the superficial peroneal nerve, the modified reversed superficial peroneal artery flap is useful in the reconstruction of ankle and foot defects that would not cause any hypoesthesia of the foot.Copyright © 2016 Elsevier Ltd and ISBI.
