Matched distal ulnar resection.

Abstract

Painful disorders of the distal radioulnar joint severely limit the work capability of the hand. Until recently, the standard treatment for this problem has been transverse resection of the distal ulna, as originally proposed by Darrach. A technique for a "matched" resection arthroplasty of the distal ulna, leaving the ulnar shaft--styloid axis along with the triangular fibrocartilage complex and the distal ulnar ligamentous attachments intact, has been used since 1967. This procedure resects the distal ulna in a long, smooth, convex curve, matching the opposing surface of the concave radial metaphysis in three dimensions. Forty-four wrists were followed for an average of 6.5 years and showed that the procedure is reliable and relieves pain while retaining a more normal ulnocarpal, radioulnar, and radiocarpal alignment, with painless pronation averaging 80.5 degrees and supination of 88.5 degrees.
