Surgical treatment of multifocal giant cell tumor of carpal bones with preservation of wrist function: case report.

We report a rare case of multifocal giant cell tumor of bone involving the trapezium, trapezoid, capitate, and scaphoid with soft tissue extension. Following intralesional resection, an autogenous corticocancellous iliac crest bone graft was used to fill the resultant defect and preserve carpal height and radiocarpal motion. Successful union with no recurrence was noted at 1-year follow-up.
