With increasing usage of many types of total elbow replacements, there is a continuing need for clinical series that report survivorship, complications and revisions, and performance of single types of implants over extended time periods. The purpose of this study was to assess the long-term effectiveness of all implants of the Sorbie-QUESTOR (SQ) unlinked surface arthroplasty conducted by a single surgeon (C.S.) over 15 years at a single site, and to determine whether there were diagnostic group differences. Between 1995 and 2002, 51 S-Q prosthetic elbows were implanted into 44 patients. The patient groups were hemophilia, rheumatoid arthritis, and "other," which included osteoarthritis, traumatic arthritis, psoriatic arthritis, and reactive arthritis. Annual evaluations included scores of pain, range of motion, and function. The most recent annual evaluation was included in the data set. Details of complications and revisions were recorded. The hemophiliac group had the best survival outcomes at 87.5%. Eighteen prostheses required revision or removal with all but 3 retained or replaced. Postoperatively, 73% rated their pain as 'slight' or 'none'. The hemophilia and rheumatoid arthritis groups made very large total flexion/extension gains. The rheumatoid arthritis group made significant forearm motion gains. Average functional assessment gains were nearly 2 grades of 5 functional levels and were significant for all groups. The S-Q surface arthroplasty has demonstrated long-term effectiveness in patients with a variety of elbow joint pathologies showing reduction in pain, large gains in joint range and function, and good long-term survival.
随着多种类型全肘关节置换术的使用日益增加，持续需要有临床系列报道来呈现长期生存率、并发症、翻修情况以及单一类型植入物在较长时间段内的性能表现。本研究的目的是评估由同一位外科医生（C.S.）在单一地点进行的15年里所有Sorbie-QUESTOR（SQ）非铰链式表面置换术植入物的长期有效性，并确定是否存在诊断分组差异。1995年至2002年期间，44例患者植入了51个S-Q人工肘关节。患者分组为血友病组、类风湿关节炎组以及“其他”组，“其他”组包括骨关节炎、创伤性关节炎、银屑病关节炎和反应性关节炎。每年的评估包括疼痛评分、活动范围和功能评分。数据集中纳入了最近一年的评估结果。记录了并发症和翻修的详细情况。血友病组的生存率最高，为87.5%。18个假体需要翻修或取出，除3个外其余均得以保留或更换。术后，73%的患者将疼痛评为“轻微”或“无”。血友病组和类风湿关节炎组的总屈伸活动度有非常大的改善。类风湿关节炎组的前臂活动度有显著改善。平均功能评估改善近2个5级功能水平等级，且对所有组均有显著意义。S-Q表面置换术已证明对患有多种肘关节病变的患者具有长期有效性，表现为疼痛减轻、关节活动范围和功能大幅改善以及良好的长期生存率。
