Excision of the distal ulna in rheumatoid arthritis.
Resection of the ulna is an effective operation in the treatment of rheumatoid disorders of the distal radioulnar joint. Tenosynovectomies of the overlying extensor tendons and synovectomy of the joint are integral parts of the procedure. Following resection, the ulna usually remains in alignment with the radius, although some dorsal displacement is common. Restoring stability to the ulna as well as reconstructing a new sheath for the extensor carpi ulnaris can be accomplished in most cases by using the extensor retinaculum. In those cases where the retinaculum has been destroyed by the disease process or when the distal ulna is severely displaced, stability can be restored using the extensor carpi ulnaris for a tenodesis.
