We assessed the long-term results of 58 Souter-Strathclyde total elbow replacements in 49 patients with rheumatoid arthritis. The mean length of follow-up was 9.5 years (0.7 to 16.7). The mean pre-operative Mayo Elbow Performance Score was 30 (15 to 80) and at final follow-up was 82 (60 to 95). A total of 13 elbows (22.4%) were revised, ten (17.2%) for aseptic loosening, one (1.7%) for instability, one (1.7%) for secondary loosening after fracture, and one elbow (1.7%) was removed because of deep infection. The Kaplan-Meier survival rate was 70% and 53% at ten and 16 years, respectively. Failure of the ulnar component was found to be the main problem in relation to the loosening. Anterior transposition of the ulnar nerve had no influence on ulnar nerve paresthaesiae in these patients.
我们评估了49例类风湿性关节炎患者中58例接受Souter-Strathclyde全肘关节置换术的长期结果。平均随访时间为9.5年（0.7至16.7年）。术前平均梅奥肘关节功能评分是30分（15至80分），末次随访时为82分（60至95分）。共有13例肘关节（22.4%）进行了翻修，其中10例（17.2%）因无菌性松动，1例（1.7%）因不稳定，1例（1.7%）因骨折后二次松动，1例肘关节（1.7%）因深部感染而被切除。Kaplan-Meier生存率在10年和16年时分别为70%和53%。发现尺侧组件的失效是与松动相关的主要问题。在这些患者中，尺神经前置对尺神经感觉异常没有影响。
