1. The lower end of the ulna can be removed without materially affecting the strength and stability of the hand or wrist.
2. If the external contour of the wrist is essentially normal, resection of the lower end of the ulna produces little change in the appearance of the wrist. If a deformity of the wrist due to radial shortening is present, the cosmetic appearance of the wrist is definitely improved following resection of the lower end of the ulna.
3. The operation is not difficult to perform, and is useful in a variety of conditions. The procedure is especially valuable to restore or increase pronation and supination in the distal radio-ulnar joint, and to relieve pain caused by arthrosis in this joint. It is also useful in correcting deformity of the wrist secondary to radial shortening.
