A case of recurrent giant cell tumor of bone in the capitate treated with total resection of the capitate and interosseous fixation of the carpus

Giant cell tumors of bone predominantly occur in the metaphysis near the end of the diaphysis, but rarely in carpal bones. We report a case of recurrent giant cell tumor (GCT) of the capitate treated by total resection of the capitate and interosseous fixation of the carpus. A 21-year-old man who first noticed pain in the right hand was diagnosed with capitate bone tumor. Iliac bone autografting was performed with GCT diagnosed histopathologically. Despite initiation of denosumab, the patient suffered recurrence and was referred to our hospital. En bloc resection was performed. Iliac bone, including cortical bone on two sides, was grafted. Fixation was achieved with headless screws in addition to bioabsorbable mesh plate. No recurrence has been seen as of two years postoperatively. GCT of carpal bones is rare. No further recurrence was observed, and the present method seemed to be effective.
