Abstract
If the replantation on the original position is not possible, the amputated tissue of a hand may be used as a donor for recovering hand functions at other positions. This procedure is termed ‘heterodigital replantation’. An 63-year-old male patient who was in press machine accident came to our hospital. He had large dorsal soft-tissue defects (5×3 cm) on his left long finger and complete amputation on his left index finger through the proximal interpharyngeal joint. Replantation was not indicated because crushing injury of index finger was severe. So we decided to use index finger soft tissue as heterodigital free flap for the coverage of the long finger defect. The ulnar digital artery and dorsal subcutaneous vein of the free flap were anastomosed with the radial digital artery and dorsal subcutaneous vein of the long finger. The heterodigital free flap provided satisfactory apperance and functional capability of the long finger. The best way to treat amputation is replantation. But sometimes surgeon confront severely crushed or multi-segmental injured amputee which is not possible to replant. In this situation, reconstructive surgeons should consider heterodigital free flap from amputee as an option.
Key Words: Free tissue flaps, Amputation, Replantation
