FOLLOW-UP OF VOLAR PLATE INTERPOSITION ARTHROPLASTY (TUPPER) OF THE METACARPOPHALANGEAL JOINTS IN RHEUMATOID HANDS: PRELIMINARY FINDINGS

We present the results of a three-year follow-up study of 59 interposition volar plate arthroplasties (Tupper) on metacarpophalangeal joints in 13 patients with erosive rheumatoid arthritis. The median age at the time of operation was 60 years (range 45-77). All patients reported lasting pain relief at rest. Improvement of hand function was, however, less satisfactory as both grip and pinch strength were compromised in all patients. Seven patients were satisfied with the outcome whereas six complained of stiffness in the operated joints. All but one patient concluded that they would have the operation again if necessary.
