Abstract
Three amputated thumbs were reconstructed with a composite osteocutaneous groin flap and a neurovascular island flap. The average age at the time of surgery was 28 (range 25–35) years. The level of the amputation was distal to metacarpophalangeal joint in two cases and proximal in one case. The injury mechanism was avulsion in all cases. The postoperative follow-up periods ranged from 27 to 30 months. There were no cases of skin necrosis, bone resorption or infection. Radiographs and three-phase bone scans showed union of the iliac bone block and the stump without any resorption in all three patients. This surgical procedure is reliable and simple and the functional results are satisfying. We reserve this technique for the treatment of thumb amputations which cannot be replanted, particularly as it does not result in bone resorption.
