Reconstruction of distal forefoot burn defect with retrograde medial plantar flap.

Burn reconstruction of forefoot remains as a difficult challenge, because the local flap alternatives are limited. We evaluated the efficiency of distally based medial plantar fasciocutaneous island flap in the coverage of forefoot defects resulting from release of toe contracture and burn debridement. Four patients with toe contractures and two patients with third degree burn in forefoot were treated between June 2004 and February 2006. The mean follow-up period was 10.4 months. The flaps were elevated as with a fasciocutaneous base on the distal medial plantar artery. The dimensions of the flaps ranged from 4cmx3cm to 5cmx4cm. The skin over the pedicle was included as a part of flap in three cases. Concomitant vein of the pedicle was anastomosed with the first plantar digital vein in four cases. In the early postoperative period, one flap used to cover third degree burn due to high-voltage electric injury was lost completely. We concluded that this flap was an appropriate alternative reconstructive option for the forefoot defect. Including skin and subcutaneous tissue over the pedicle to flap protects the pedicle against kinking and compression. Venous supercharging of the flap improves venous drainage.
