Distally Based Dorsal Pedal Neurocutaneous Flap for Forefoot Coverage

Abstract

The authors describe their experience with the use of the distally based dorsal pedal neurocutaneous flap for distal foot coverage. Ten patients underwent reconstruction with 13 flaps between 2004 and 2008. One patient suffered from a traffic accident and 9 from electrical injury. All of the soft tissue defects resulted in metatarsophalangeal joint and phalanx bone exposure. The size of the flaps ranged from 6 × 2 cm to 11 × 6 cm. The flaps were elevated based on intermediate or medial dorsal pedal nerves. Nine flaps were harvested in first stage to repair the distal foot. Among them, 3 showed partial necrosis in the distal region because of venous insufficiency. Four flaps underwent a surgical delay procedure in the first stage and were then transferred to reconstruct phalanx wounds in the second stage, surviving completely. All patients were satisfied with their reconstruction and donor site contour. The distally based dorsal pedal neurocutaneous flap can be used to repair the distal foot soft tissue defects, providing sufficient skin territory and excellent aesthetic and functional recovery. Surgical delay effectively enhances the distally based dorsal pedal neurocutaneous flap survival, particularly for the large size flaps.
