Twenty-four elbows with rheumatoid arthritis underwent total replacement arthroplasty with insertion of a hingeless surface-replacement prosthesis. These were followed for an average of three years and ten months. Excellent results were seen in fourteen elbows; fair, in seven; and poor, in three. Satisfactory pain relief as well as good stability were obtained in all but one elbow. Two elbows did not regain a useful range of motion. Proximal migration of the humeral component was seen in one elbow, and persistent subluxation with pain and instability was seen in another. No other major complications were encountered. The very low incidence of loosening in this series seems to substantiate the sound principle of the use of this type of hingeless prosthesis.
24例类风湿性关节炎患者的肘部接受了无铰链表面置换假体植入的全关节置换术。对这些患者平均随访了3年零10个月。14例肘部效果极佳；7例良好；3例较差。除1例肘部外，其余所有肘部均获得了满意的疼痛缓解和良好的稳定性。2例肘部未能恢复有效的活动范围。1例肘部出现肱骨组件近端移位，另1例肘部持续半脱位并伴有疼痛和不稳定。未遇到其他主要并发症。该系列中假体松动的发生率极低，似乎证实了使用这种无铰链假体的合理原则。
