The plantar digital web space island flap for reconstruction of the distal sole

A neurovascular flap of interdigital web space skin based on the plantar circulation is described. The flap is useful for reconstructing distal plantar defects that do not have an adequate surface for skin grafting. It leaves a donor defect in a non-weight-bearing area and does not disrupt the structural integrity of the foot. The surgical anatomy and operative approach are detailed. The key to the approach is to preserve the fat pad around the neurovascular bundle during the dissection. Six patients have successfully undergone this procedure and have been followed for at least 2 years postoperatively. The plantar island flap is a reliable flap for repairing plantar defects overlying the metatarsal heads.
