Distal radioulnar allograft reconstruction after giant cell tumor resection.

Giant cell tumor of bone is considered to be a benign, locally aggressive lesion. When diagnosed early, it can be successfully treated with wide en bloc excision. No reports of complete distal radioulnar allograft reconstruction after en bloc excision of a distal ulnar lesion were found in the literature. We report a case of a distal ulnar giant cell tumor treated with wide en bloc excision and 2-stage allograft reconstruction and followed up for 40 months.
