Does wrist fusion cause destruction of the first carpometacarpal joint in rheumatoid arthritis? 18 patients followed for 2-6 years.
We evaluated radiographic destruction of the first carpometacarpal joint (CMC I) in 18 hands with wrist fusions and compared it with the unoperated contralateral hands preoperatively and after a follow-up of a mean of 4.4 (2-6) years. Patients were obtained from a prospective 20-year follow-up study of 103 patients with seropositive rheumatoid arthritis. The degree of destruction in the CMC I-joints was evaluated with Larsen grades. The mean value of Larsen indices for CMC I was 0.9 before wrist fusion and 2.5 (p < 0.001) at the follow-up, compared to 0.8 and 1.3 (p = 0.06) in the control hands, respectively. No preoperative difference was found between the hands to be fused and the control hands, but the difference was significant (p = 0.009) after the follow-up.
