OBJECTIVETo analyze the feasibility of reverse island flaps pedicled with cutaneous nerve nutrient vessels in repairing the defect on distal parts of extremities.

METHODSThirty patients with tissue defect in distal extremities, complicated by exposed vessels, nerve, tendons, and/or bones ,were repaired with island flaps pedicled with neurocutaneous nutrient vessel. Among them, five cases were grafted with flaps with external forearm cutaneous nerve vessels, eleven cases were grafted with flap containing sural neural nutrient vessels in its pedicle,and 14 cases with saphenous nerve nutrient vessels in the pedicles.

RESULTSThe flaps of 28 cases survived with perfect appearance and function. In one case partial necrosis occurred because of compression on the pedicle, but the patient healed after dressing, and another case with necrosis of the edge of the flap due to infection, but also healed after skin grafting.

CONCLUSIONThe reverse island flaps pedicled with cutaneous nerve nutrient vessels which are constant in anatomy, with reliable blood supply, can be recommended because its simple operative technique, non-injurious to main blood vessels and muscles, the repair of distal defects of the extremities.
