Rheumatoid wrists treated with synovectomy of the extensor tendons and the wrist joint combined with a Darrach procedure.

Abstract

Forty-three rheumatoid wrists in 43 patients with bilateral wrist involvement were treated with synovectomy of the extensor tendons and wrist joint combined with a Darrach procedure in the period from 1966 to 1986. Clinical and radiologic assessment of the wrists was carried out after an average follow-up period of 11 years, with comparison of the treated and the opposite untreated wrists. The authors confirmed what others have concluded regarding the operation: pain was generally decreased, forearm rotation increased, and wrist extension and palmar flexion changed little. Radiologically, carpal collapse and palmar carpal subluxation progressed nearly parallel to the opposite wrists, but ulnar carpal shift was much greater in the surgically treated wrists. Therefore it is suggested that some measure to prevent ulnar carpal shift, such as Clayton's tendon transfer or radiolunate arthrodesis, should be included in this operation.
