Severe electric injuries of the hand and forearm.

Electrical injuries of the upper limb produce major destruction of tissue mainly affecting the forearm, since the hand is usually the site of entry of current. Limb salvage, if it is to be successful, requires the rapid institution of a number of surgical procedures. Vein grafting to restore blood supply is frequently required and just as frequently requires skin flap cover following adequate debridement. The most commonly used flap is the groin flap. Despite the progression of necrosis beneath the flap for a period of up to three weeks, healing is usually successful and it is usually possible to avoid amputation. Several surgical procedures are required as a rule. The initial surgery is followed, in order, by nerve graft, tendon transfer and skin transfer following the use of tissue expanders. Results long term, with regard to function and appearance, were judged good.
