Repair of skin defects of the fingers with dorsal reverse island neurocutaneous flaps from the hand and finger

Abstract

Objective To evaluate the treatment outcome of using dorsal reverse island neurocutaneous flaps from dorsum of the hand or finger for repair of finger skin defects. Methods Eighteen reverse island flaps (in 18 cases) pedicled on the nutritional vessels of dorsal metacarpal cutaneous nerve and 17 reverse island flaps (in 15 cases) pedicled on the nutritional vessels of dorsal branch of the proper digital nerve were used to repair skin defects of the fingers. The survival rate, texture, colour, and sensation of the flaps were observed.Results Swelling of the flap occurred in 2 cases, while venous crisis was seen in 2 cases. All 35 flaps of the 33 eases survived. Postoperative follow up period ranged from 3 to 18 months, with an average of 12 months. The appearance, texture and elasticity of the flaps were good. Partial recovery of light touch was observed.Conclusion Harvest of dorsal reverse island neurocutaneous flap does not sacrifice major vessels and nerves.The operation is simple. It is an ideal method for repairing soft tissue defects of the finger. Key words: Finger injuries; Surgical procedures, operative; Island flaps
