Wrist deformity in rheumatoid arthritis extensor carpi ulnaris tendon transfer.

A procedure designed to correct volar subluxation of the ulnar carpus in patients with rheumatoid wrist deformity is described. Twenty-five patients were treated with synovectomy, distal ulna resection, and transfer of the distal extensor carpi ulnaris to the extensor carpi radialis longus. Comfort and improved function were reported, and no significant complications were noted. Follow-up during the 14-month study period demonstrated improvement in volar-carpal subluxation confirmed on x-ray films, stability of metacarpal-phalangeal alignment, and no deterioration of the ability to ulnar deviate.
