Abstract
A personal series of twelve wrist arthroplasties performed on ten patients with rheumatoid arthritis of the radio-carpal joint were reviewed in retrospect. Six arthroplasties were of the Meuli metal/plastic/metal design and six were of the Swanson silastic type with an additional silastic ulnar head prosthesis. Both prostheses were successful in giving a pain free stable joint with some degree of useful movement. The Meuli appeared to give a greater range of movement than the more constrained Swanson prosthesis. Although complications were encountered it is concluded that wrist arthroplasty does have a place in the management of patients with rheumatoid arthritis of the radio-carpal joint. Our present policy is to continue with the use of the Swanson design because of the advantages of a cement free prosthesis.
