Matched distal ulna resection for posttraumatic disorders of the distal radioulnar joint.

Abstract

In 1985 we published the results of the matched ulna resection in 44 patients, the majority of whom had rheumatoid arthritis. The matched ulna resection maintains the continuity of the distal ulna to the ulnar sling mechanism, including the triangular fibrocartilage complex (TFCC), and resects the distal ulna in a smooth, curved, convex fashion to match the contour of the radius throughout forearm rotation. This article presents the results of the procedure in patients with posttraumatic and mechanical disorders of the distal radioulnar joint. Good to excellent results were noted in 24 of 32 patients. The outcome was related to the severity of the patient's initial problem.
