Surgical Principles and Planning for the Rheumatoid Hand and Wrist

Abstract

Each surgical procedure available for the rheumatoid hand has a score card. The most indicated and necessary procedures include: extensor tenosynovectomy and Darrach for the impending or already ruptured extensor tendons; flexor tenosynovectomy and carpal tunnel release for the patient with impaired median nerve function; stabilization of the deformed unstable thumb with MP or IP arthrodesis; and flexor tenosynovectomy in the palm and finger of a motivated patient with significant disparity between active and passive motion. Relative indications for surgery include arthrodesis for the unstable wrist; MP arthroplasty for the fixed MP volar and ulnar subluxation with inability to open the hand; synovectomy for the occasional patient with painful boggy synovitis of the MP or PIP joint; and reconstruction of the fixed swan neck deformity with relatively good PIP joints. Both MP and PIP joints can and should be operated on at the same time. Extensive wrist surgery, that is, tenosynovectomy and Darrach or arthrodesis, should not be performed at the same time as MP arthroplasty. Try to do the "winner operations" first.
