The data on convertible total elbow arthroplasty are limited and primarily based on multiple centre/multiple surgeon series. The aim of this study was to report the mid-term functional outcomes, radiological findings, complications and survivorship of the Latitude total elbow arthroplasty performed by a single surgeon.
STUDY DESIGN & METHODS: The study included 13 patients (10 females, mean age of 72 years and varying indications) over eight years. The Oxford Elbow Score (OES), Mayo Elbow Performance Score (MEPS), range of movements (ROM), Subjective Elbow Value (SEV), satisfaction score (SS) and the revision rate of the implant per 100 observed component years (OCY) were assessed.
The mean follow-up was 5.9 years (3-10 years). The Oxford Elbow Score/Mayo Elbow Performance Score improved from 15 to 42 ( value < 0.005)/26% to 93% ( value < 0.005) respectively. The arc of extension-flexion/supination-pronation improved from 63° to 106° ( = 0.00002)/123° to 142° ( = 0.32) respectively. The Subjective Elbow Value/Satisfaction Score was 83/98 respectively. There was one re-operation for a deep infection. There were no radiologic signs of loosening and the revision rate was 0.15 per 100 observed component years.
With careful patient selection, convertible total elbow arthroplasty provides patients with good to excellent outcomes and substantial improvements in the range of movements.
关于可转换全肘关节置换术的数据有限，且主要基于多中心/多位外科医生的系列研究。本研究的目的是报告由单一外科医生进行的Latitude全肘关节置换术的中期功能结果、影像学表现、并发症及假体生存率。
本研究纳入了8年间的13例患者（10名女性，平均年龄72岁，适应证各异）。评估了牛津肘关节评分（OES）、梅奥肘关节功能评分（MEPS）、活动范围（ROM）、主观肘关节价值（SEV）、满意度评分（SS）以及每100个观察组件年（OCY）的假体翻修率。
平均随访时间为5.9年（3 - 10年）。牛津肘关节评分/梅奥肘关节功能评分分别从15分提高到42分（P值＜0.005）/从26%提高到93%（P值＜0.005）。屈伸/旋前旋后弧度分别从63°提高到106°（P = 0.00002）/从123°提高到142°（P = 0.32）。主观肘关节价值/满意度评分分别为83/98。有1例因深部感染进行了再次手术。没有假体松动的影像学迹象，每100个观察组件年的翻修率为0.15。
通过谨慎选择患者，可转换全肘关节置换术能为患者带来良好至优异的结果，并使活动范围得到显著改善。
