The shoulder joints of 105 patients with rheumatoid arthritis were examined. The patients were on average 62 years old and their mean RA duration 17 years. Ninety-six patients (91%) reported shoulder problems. Thirty-three patients had actual severe painful shoulder disability. The acromioclavicular joint was clinically tender in 36 shoulders and subacromial hypertrophic bursitis was recorded for 22 shoulders. One hundred and sixteen shoulders in 61 of the patients with shoulder pain were examined radiologically and classified according to the Larsen system. With increasing duration of the RA there was a progress of destructive changes and a decrease in the range of motion, indicating that intervention with surgical procedures may be warranted.
对105例类风湿性关节炎患者的肩关节进行了检查。患者平均年龄62岁，类风湿性关节炎平均病程17年。96例（91%）患者报告有肩部问题。33例患者存在严重的肩部疼痛性残疾。36个肩关节的肩锁关节有临床压痛，22个肩关节记录有肩峰下肥厚性滑囊炎。对61例肩部疼痛患者的116个肩关节进行了放射学检查，并根据拉森系统进行分类。随着类风湿性关节炎病程的延长，破坏性改变进展，活动范围减小，这表明可能有必要进行手术干预。
