The available literature on the use of a cementless total elbow arthroplasty (TEA) design and its results are limited. This clinical study reports the outcome of the cementless Discovery elbow system.
Patients were operated on by a single surgeon between 2007 and 2014. Nineteen patients (20 elbows) were available for review, 2 women (1 bilateral TEA) and 17 men. The age of the patients ranged from 27 to 75 years (mean, 48 years). The mean follow-up was 61.8 months (range, 12-156 months). Patients were assessed for range of motion, pain, and satisfaction level. Outcome scores included the Mayo Elbow Performance Score, the Liverpool Elbow Score, and the 12-Item Short Form Health Survey (version 1). Radiographs were reviewed to evaluate for loosening.
The mean Mayo Elbow Performance Score was 77.25, and the mean Liverpool Elbow Score was 6.76. The mean flexion range was 123°, and the mean extension lag was 35°. The mean pronation was 59°, and the mean supination was 58°. On radiologic evaluation, there were no signs of loosening; however, in 2 cases, nonprogressive radiolucent lines were observed. No signs of infection were detected at final follow-up, and no elbows were revised. More than 90% of patients were satisfied with the overall outcome.
The cementless TEA seems to be a reliable option for treatment of varying elbow diseases. Long-term results are needed to assess the survivorship of this design.
关于非骨水泥型全肘关节置换术（TEA）设计及其结果的现有文献有限。本临床研究报告了非骨水泥型Discovery肘关节系统的治疗结果。
2007年至2014年间由一名外科医生为患者实施手术。19例患者（20个肘关节）可供评估，其中2例女性（1例双侧TEA）和17例男性。患者年龄范围为27至75岁（平均48岁）。平均随访时间为61.8个月（范围12 - 156个月）。对患者进行活动范围、疼痛和满意度评估。结果评分包括梅奥肘关节功能评分、利物浦肘关节评分和12项简明健康调查（第1版）。复查X线片以评估松动情况。
梅奥肘关节功能评分平均为77.25，利物浦肘关节评分平均为6.76。平均屈曲范围为123°，平均伸直滞后为35°。平均旋前为59°，平均旋后为58°。影像学评估未见松动迹象；然而，2例患者观察到非进行性透亮线。末次随访未发现感染迹象，无肘关节翻修。超过90%的患者对总体结果满意。
非骨水泥型TEA似乎是治疗各种肘关节疾病的可靠选择。需要长期结果来评估该设计的生存率。
