Surgical Treatment for Ulnar Head Syndrome in Rheumatoid Arthritis
並列摘要
The clinical data and roentgenogram of 44 rheumatoid wrists with ulnar head syndrome in 36 patients were reviewed. The average follow-up period was 39 months postoperatively. Twenty-five wrists had attrition rupture of extensor tendons and 18 had unstable radiocarpal joints. Synovectomy, resection of ulnar head, and distal radioulnar joint reconstruction which stabilized the distal ulna rendered satisfactory results in wrists with stable radiocarpal joints. However, in the wrists with unstable radiocarpal joint, 3 were found to develop marked ulnar translation due to lack of simultaneous radiocarpal stabilizing procedure. All of the remaining cases which were treated with simultaneous radiocarpal implant, arthrodesis or Sauve-Kapandji procedure had satisfactory results without significant ulnar translation. Our experience prompted us to develop a simple but practical classification of rheumatoid ulnar head syndrome. An operation protocol is also recommended according to this classification.
