Free Osteoarticular Metatarsal Transfer for Giant Cell Tumor of Metacarpal—a Surgical Technique

[摘要] Giant cell tumor is a relatively uncommon tumor of bones accounting for 5% of all the primary bone tumors. In the small bones of hands it occurs even more rarely. Only 2–5% of all the giant cell tumors have been reported to affect the hand and metacarpal involvement is much less common than a phalangeal one [1–4]. The tumor occurring at this site commonly presents at an advanced stage and is associated with more bony destruction thereby complicating treatment [5–8]. Also these are associated with higher rate of recurrence [2]. The various treatment modalities described are curettage with or without bone grafting, en bloc resection and reconstruction and ray amputations [2] . We here describe a case of successful transplantation of 4th metatarsal along with its osteo-articular ligamentous complex to replace the 5th metacarpal bone which was the site of tumor. This enabled us to preserve the full function of the metacarpo-phalangeal joint by a relatively simple technique.
