[Giant cell tumor of the ulna, treated by resection and bone grafting].

Bone tumours with a tendency to recur or whose benign nature is doubtful should be treated by resection of the tumour-bearing segment and not by simple curettage, as this does not provide for complete excision. This technique is illustrated by the example of an atypically situated giant-cell tumour of the ulna in a child, which was treated by en bloc resection, following which the defect was bridged by a cortico-cancellous bone graft.
