Fig. 2. (A) Arthritic change in the distal radioulnar joint results in dorsal subluxation of the ulnar head or ulnocarpal impingement. (B) In the Darrach procedure, the ulnar head is resected and the proximal stump is stabilized by extensor carpi ulnaris. (C) In the Sauvé-Kapandji procedure, the ulnar support of the wrist is preserved by arthrodesis of the distal radioulnar joint. The resection of the ulna is made proximal to the arthrodesis, which creates a pseudarthrosis to allow forearm rotation (Drawings are authors’ own artwork).
