The composite groin fascial free flap

Seven patients with extensive loss of soft tissue, extensor tendon, and exposure of bone and joint of dorsum of hand and foot were treated with free composite flaps from the groin area. To retard the adhesion by scarring, membrane interposition between tendon and bone was recommended. The groin flap, based on superficial circumflex iliac vessels, was combined with a well-vascularized external oblique aponeurosis. The groin skin flap provided skin coverage, and the aponeurosis was used simultaneously to create a gliding surface for reconstructed tendons in a single one-stage procedure. All composite free-tissue transfers were successful. The advantages of this technique are: (1) a single, one-stage procedure; (2) fewer adhesions of reconstructed tendons, and no need of secondary tenolysis; and (3) good cosmesis and minimal morbidity at donor site.
