Abstract
Purpose
This study aimed to determine the results of radiolunate arthrodesis for rheumatoid arthritis (RA) after a long-term follow-up period of up to 20 years under tight postoperative medical control of RA. We also compared the results between patients with and without degenerative changes in the midcarpal joints at follow-up. We determined the radiologic factors predictive of secondary degenerative changes in the midcarpal joint.
Methods
This was a long-term retrospective analysis of 16 wrists of 14 patients with RA treated with radiolunate arthrodesis first reported in 2013. The mean follow-up period was 14 years (range, 8–23 years; SD, 4.6 years). Ten wrists had a Larsen classification of grade III, whereas 6 wrists had grade IV. The range of motion was assessed, and clinical outcomes were graded using the Mayo Wrist Score and Stanley classification system. The Carpal Height Index, Ulnar Translation Index, and changes in the midcarpal joint contour were determined from radiographs. We categorized the changes in the midcarpal joint as unchanged or degenerative.
Results
At final follow-up, the clinical scores improved; however, the extension and flexion range of motion was significantly reduced compared with that before surgery. The Carpal Height Index and Ulnar Translation Index improved immediately after surgery and remained stable at final follow-up. The changes in the midcarpal joint were categorized as unchanged in 6 wrists and degenerative in 10 wrists. The clinical outcomes were similar between the groups. The mean preoperative Ulnar Translation Index was significantly higher in the degenerative group than in the unchanged group.
Conclusions
Radiolunate arthrodesis in patients with RA maintained good clinical results and corrected alignment, even during long-term follow-up. Preoperative severe ulnar translation deformity was a risk factor for postoperative degeneration of the midcarpal joint, and pre-existing degenerative changes at the midcarpal joint might lead to loss of wrist range of motion.
