Radio-lunate limited arthrodesis (RLA) is an established surgical intervention for damaged rheumatoid arthritis (RA) wrists. The goal of RLA is to conserve the range of motion (ROM) and level of activities of daily life (ADL) by delaying more extensive fusion. In this study, we retrospectively reviewed the outcome of RLA with ulnar head resection (UHR) in terms of pain score, ROM, and radiographic parameters, including carpal height ratio, ulnar translation ratio, and palmar subluxation. The clinical factors, such as dose of corticosteroids per day and laboratory examination data before surgery, including C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and rheumatoid factor (RF), did not influence the results of the surgery. The changes in these clinical factors were also statistically analyzed in relation to the Schulthess classification of preoperative radiographs of wrists reported by Simmen and Huber: Type I (ankylosis type), Type II (osteoarthritis type), and Type III (disintegration type). This study hypothesized that RLA with UHR would provide no significant improvement in Type III wrists. The results showed that RLA with UHR resulted in stable wrists with excellent pain relief and with limited, but temporary, functional ROM, suggesting that this procedure seems to be applicable for all types of wrists within this group of patients.
