Twenty-eight nonconstrained capitellocondylar elbow offhroplasties were performed in 23 patients. The clinical criteria were intractable pain in a joint with radiologic destruction from rheumatoid arthritis. Patients were examined at an average of 35 months postsurgery with the Ewald scoring system. Results were satisfactory in 24 elbows (86%) and unsatisfactory in four (14%). Pain relief and functional improvement were dramatic. The average arc of motion increased from 88 degrees preoperation to 101 degrees postoperation. There was an average 33 degrees residual flexion contracture. There was one failure from loosening, but no radiographic or clinical loosening was detected in the remaining patients. Postoperative dislocation was the most frequent complication, occurring in four cases. One dislocation required revision while three stabilized following four weeks of immobilization. There were two remote infections occurring two and five years postoperation. Although complications are frequent, this is a predictably successful procedure in properly selected patients.
对23例患者实施了28例非限制性人工肱桡关节置换术。临床标准为类风湿性关节炎导致关节出现放射性破坏且伴有顽固性疼痛。术后平均35个月采用埃瓦尔德评分系统对患者进行检查。24例肘关节（86%）结果满意，4例（14%）不满意。疼痛缓解和功能改善显著。平均活动弧度从术前的88度增加到术后的101度。平均残留屈曲挛缩为33度。有1例因松动失败，但其余患者未发现影像学或临床松动。术后脱位是最常见的并发症，发生4例。1例脱位需要翻修，3例在固定4周后稳定。术后2年和5年分别发生2例远期感染。虽然并发症常见，但在选择合适的患者时，这是一种可预见的成功手术。
