Assessment of Surgery of the Rheumatoid Wrist

Abstract

A series of 314 wrist operations performed on 227 patients with rheumatoid arthritis is presented. In 266 hands various wrist operations were undertaken with the object of synovial debridement and in 48 hands the wrist was also arthrodesed. The mean age at the time of surgical treatment was 51 years and the mean period of observation 4.2 years. This study shows that the main benefits of synovectomy are related to a constant and marked pain relief and prevention of tendon ruptures. The hope that synovectomy might arrest or prevent skeletal destruction was not realized and progression of X-ray changes was found in 74%. The very low recurrence rate in the present series as judged by clinical signs is probably not very significant and it is concluded that the X-ray findings are the most reliable criteria reflecting the real activity in a rheumatoid joint. In several wrists where prophylactic ulnar head resection had been performed through a small ulnar incision, an active dorsal tenosynovitis with tendon invasion developed later. These and other findings at the operation indicate that the erosive eftect of the distal end of the ulna is certainly not the sole cause of tendon rupture in this area and that a complete exposure and decompression of the tendons should regularly be performed. Finally, arthrodesis of the wrist was so successful that it can be highly recommended.
