[Purpose] To examine the humeral head positions while wearing an abduction brace in the sitting and supine positions in healthy adults and patients who have been operated on for shoulder joint diseases. [Participants and Methods] Thirty participants were included in the study, of which 15 were healthy adults (without any orthopedic diseases) and 15 had shoulder diseases (post-arthroscopic repair of a rotator cuff tear). The acromion and humeral head were observed on ultrasound. The acromiohumeral distance was measured once in two different positions while wearing the brace: edge sitting and supine. [Results] The mean acromiohumeral distance in the healthy group was 7.9 ± 1.1 mm while sitting and 7.2 ± 1.0 mm in the supine position. In the disease group it was 7.6 ± 0.9 mm while sitting and 6.3 ± 1.1 mm in the supine position. Multiple logical regression revealed that the acromiohumeral distance was not affected by the participant's age, height, or weight. [Conclusion] The acromiohumeral distance was significantly reduced in the supine position despite the use of an abduction brace. Therefore, patients must use a pillow/towel to support the shoulder joint to prevent unnecessary stress while the cuff tendons are healing.
[目的] 研究健康成年人以及接受过肩关节疾病手术的患者在佩戴外展支具时，于坐姿和仰卧位下肱骨头的位置。[参与者与方法] 本研究纳入30名参与者，其中15名是健康成年人（无任何骨科疾病），15名患有肩部疾病（肩袖撕裂关节镜修复术后）。通过超声观察肩峰和肱骨头。在佩戴支具时，于坐姿边缘位和仰卧位这两个不同体位下各测量一次肩峰肱骨头距离。[结果] 健康组坐姿时肩峰肱骨头平均距离为7.9±1.1 mm，仰卧位时为7.2±1.0 mm。疾病组坐姿时为7.6±0.9 mm，仰卧位时为6.3±1.1 mm。多元逻辑回归显示，肩峰肱骨头距离不受参与者年龄、身高或体重的影响。[结论] 尽管使用了外展支具，但仰卧位时肩峰肱骨头距离仍显著减小。因此，在袖带肌腱愈合期间，患者必须使用枕头/毛巾支撑肩关节，以防止不必要的压力。
