The Latitude total elbow arthroplasty (TEA) is an implant with limited published data on its performance and outcomes. The aim of this study was to report the short-term outcomes of the Latitude TEA as well as to describe the radiographic outcomes and complications.
The Latitude was implanted in 20 patients (23 elbows) in a linked configuration. Patients were recalled to clinic for the assessment of their range-of-motion and compared to preoperative values. Administration of functional outcome measures was also performed.
Mean follow-up was 4.7 years (range, 1 to 7.5 years) with four elbows requiring revision. The flexion-extension arc improved from 86.6 to 101.3 (range, 76 to 126) postoperatively (p = 0.04). The average Disabilities of the Arm, Shoulder, and Hand score was 28.1 (range, 5.8 to 50.4) and the average Mayo Elbow Performance Score was 89.6 (range, 76 to 100), with 83% of elbows scoring in the good or excellent range. Radiolucencies were detected in 60% of patients and 31% of these lucencies progressed in size at the time of follow-up.
The Latitude prosthesis provides patients with favorable clinical outcomes with improvements in their range-of-motion and a complication rate comparable to other elbow arthroplasty implants.
Latitude全肘关节置换术（TEA）是一种植入物，关于其性能和结果的已发表数据有限。本研究的目的是报告Latitude TEA的短期结果，并描述影像学结果和并发症。
以连接配置将Latitude植入20例患者（23个肘关节）。召回患者到诊所评估其活动范围，并与术前值进行比较。还进行了功能结果测量。
平均随访4.7年（范围1至7.5年），4个肘关节需要翻修。术后屈伸弧从86.6改善至101.3（范围76至126）（p = 0.04）。手臂、肩部和手部残疾平均评分为28.1（范围5.8至50.4），梅奥肘关节功能评分平均为89.6（范围76至100），83%的肘关节评分为良好或优秀。60%的患者检测到透亮区，其中31%的透亮区在随访时尺寸增大。
Latitude假体为患者提供了良好的临床结果，活动范围得到改善，并发症发生率与其他肘关节置换植入物相当。
