Wrist joint arthroplasty in rheumatoid arthritis: a comparison between the Meuli and Swanson prostheses. 1984

B Summers, and M J Hubbard

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.

D001172 Arthritis, Rheumatoid A chronic systemic disease, primarily of the joints, marked by inflammatory changes in the synovial membranes and articular structures, widespread fibrinoid degeneration of the collagen fibers in mesenchymal tissues, and by atrophy and rarefaction of bony structures. Etiology is unknown, but autoimmune mechanisms have been implicated. Rheumatoid Arthritis
D012826 Silicone Elastomers Polymers of silicone that are formed by crosslinking and treatment with amorphous silica to increase strength. They have properties similar to vulcanized natural rubber, in that they stretch under tension, retract rapidly, and fully recover to their original dimensions upon release. They are used in the encapsulation of surgical membranes and implants. Elastomers, Silicone,Rubber Silicone,Silicone Rubber,Elastosil,Microfil,SE-30,Elastosils,Microfils,SE 30,SE30,Silicone Elastomer
