To assess the optimal fusion angle of the elbow to accommodate the activities of daily living.
The study enrolled 30 healthy adult volunteers (mean age 24 years), who performed 29 activities with an elbow brace fixed at various flexion angles (30°, 50°, 70°, 90°, 110°, 120°). The activities were divided into three groups: the activities of daily living, personal care and hygiene, and modern activities of daily living. Activity performance was scored on a scale previously designed to assess the difficulty of performing a particular activity. Results, The highest overall score for all activities was at 90° elbow flexion (79.70±4.11), followed by 110° (76.17±4.01) and 70° (75.43±6.64). For modern activities of daily living, the highest score (43.77±1.33) was also at 90°. The 90° angle also allowed the highest percentage (86.6%) of task completion in all activity groups. Conclusion, Our study supports making elbow arthrodesis at 90° of flexion, which may also be applied to modern daily living activities. However, patients should be consulted about the preferred angle for elbow arthrodesis, as no single fusion angle allows for the performance of all modern daily living activities.
评估肘关节的最佳融合角度以适应日常生活活动。
该研究招募了30名健康成年志愿者（平均年龄24岁），他们在肘关节固定于不同屈曲角度（30°、50°、70°、90°、110°、120°）的情况下进行29项活动。这些活动分为三组：日常生活活动、个人护理与卫生以及现代日常生活活动。活动表现根据先前设计的用于评估执行特定活动难度的量表进行评分。结果，所有活动的总体最高分出现在肘关节屈曲90°时（79.70±4.11），其次是110°（76.17±4.01）和70°（75.43±6.64）。对于现代日常生活活动，最高分（43.77±1.33）同样出现在90°时。90°角度在所有活动组中也允许最高比例（86.6%）的任务完成。结论，我们的研究支持在屈曲90°时进行肘关节融合术，这也可能适用于现代日常生活活动。然而，应就肘关节融合术的首选角度咨询患者，因为没有单一的融合角度能允许进行所有现代日常生活活动。
