Sixty-nine non-constrained capitellocondylar metal-to-plastic total elbow-replacement prostheses were implanted in sixty-four patients with rheumatoid arthritis. These patients were followed for an average of 3.5 years. Postoperative flexion and pronation were significantly improved, but no significant increase in postoperative extension or supination could be demonstrated. Based on a rating system evaluating pain and function, there were 87 per cent good or excellent results. The complication rate based on the total number of prostheses implanted was 39 per cent. Eight patients required revision of the arthroplasty: four for dislocation of the prosthesis, two for sepsis, one for loosening, and one for a fracture. Eight other asymptomatic patients showed minimum radiolucent lines adjacent to the ulnar component. No patient demonstrated radiolucent lines adjacent to the humeral component.
六十九例非限制性肱骨头髁金属对塑料全肘关节置换假体被植入六十四例类风湿性关节炎患者体内。这些患者平均随访3.5年。术后屈曲和旋前明显改善，但术后伸展或旋后未显示出明显增加。基于评估疼痛和功能的评分系统，87%的结果为良好或优秀。基于植入假体总数的并发症发生率为39%。八名患者需要进行关节成形术翻修：四名因假体脱位，两名因败血症，一名因松动，一名因骨折。另外八名无症状患者在尺骨组件附近显示出最小的透亮线。没有患者在肱骨组件附近显示出透亮线。
