Background Previous study demonstrated that distal radioulnar joint (DRUJ) plays a biomechanical role in extension and flexion of the wrist and suggested that fixation of the DRUJ could lead to loss of motion of the wrist. Little is known about the pre- and postoperative range of motion (ROM) after the Sauvé-Kapandji (S-K) and Darrach procedures without tendon rupture. To understand the accurate ROM of the wrist after the S-K and Darrach procedures, enrollment of patients without subcutaneous extensor tendon rupture is needed. Purpose This study aimed to investigate the pre- and postoperative ROM after the S-K and Darrach procedures without subcutaneous extensor tendon rupture in patients with rheumatoid arthritis (RA) and osteoarthritis (OA). Methods This retrospective study included 36 patients who underwent the S-K procedure and 10 patients who underwent the Darrach procedure for distal radioulnar joint disorders without extensor tendon rupture. Pre- and postoperative ROMs after the S-K and Darrach procedures were assessed 1 year after the surgery. Results In the S-K procedure, the mean postoperative ROM of the wrist flexion (40 degrees) was significantly lower than the mean preoperative ROM (49 degrees). In wrist extension, there were no significant differences between the mean preoperative ROM (51 degrees) and postoperative ROM (51 degrees). In the Darrach procedure, the mean postoperative ROM of the wrist flexion and extension increased compared with the mean preoperative ROM; however, there were no significant differences. Conclusion In the S-K procedure, preoperative ROM of the wrist flexion decreased postoperatively. This study provides information about the accurate ROM after the S-K and Darrach procedures. Level of Evidence This is a Level IV, therapeutic study.
