Results from resection of the distal end of the ulna after fractures of the lower end of the radius.

Pain, impaired mobility and weakness in the wrist are common complications after fractures of the lower end of the radius. When these symptoms persist, resection of the distal end of the ulna has been the surgical treatment of choice. 24 patients who had undergone this procedure were reviewed. 50% stated they were not improved by the operation. Of 11 patients with degenerative changes in the distal radio-ulnar joint on preoperative X-ray, 8 stated they were helped by the operation, while of 13 patients without any signs of arthrosis in the distal radio-ulnar joint, only 4 experienced relief of their discomfort. A more discriminating approach to the treatment of the sequelae of fractures to the lower end of the radius is required. Resection of the distal end of the ulna is probably only indicated when the distal radio-ulnar joint shows sings of arthrosis.
