Ulnar translocation after excision of giant cell tumour of distal radius.

Translocation of the ipsilateral ulna has been carried out in six cases after radical resection of a giant cell tumour of the distal radius. The carpo-ulnar junction united readily in all cases. Union of the radio-ulnar junction is often delayed, but this can be overcome by the addition of cancellous grafts at the time of ulnar translocation. All the patients had very good forearm rotation and an acceptable appearance. There were no significant complications.
