The lateral supramalleolar flap.

An anatomic study (40 fresh dissected specimens) and clinical experience (14 patients) have shown the reliability of a skin flap designed on the lower third of the lateral aspect of the leg. It is supplied by a cutaneous branch from the perforating branch of the peroneal artery. This perforating branch continues distally deep to the fascia along the anterior ankle and into the foot. This can be used as a reversed pedicle, giving the flap an arc of rotation that allows coverage of the dorsal, lateral, and plantar aspects of the foot, the posterior heel, and the lower medial portion of the leg.
