Recurrent metacarpal giant cell tumour treated by en bloc resection and metatarsal transfer.

Recurrent giant-cell tumours of bone have a higher risk of malignancy than primary giant-cell tumours of bone, and giant-cell tumours of bone in the hand are more likely to recur than those that arise elsewhere. Therefore, en bloc resection and reconstruction, or amputation, have been the accepted treatments for recurrent giant-cell tumours of bone in the hand. We describe two cases of successful transplantation of a metatarsal to a metacarpal, which was the site of a recurrent giant-cell tumour. The patients had satisfactory results 3 years later without problems in the foot. En bloc resection of the tumour and reconstruction with an autograft should be considered in the treatment of recurrent giant cell tumour of the hand.
