背景：了解正常盂肱几何形状对于肩关节置换术中的解剖重建很重要。不幸的是，亚洲人群盂肱关节的细节尚未得到充分评估。本研究的目的是评估正常日本人群盂肱关节的 3 维几何形状，并阐明其形态特征。方法：使用来自健康日本志愿者的 160 个正常肩部的计算机断层扫描对盂肱关节进行人体测量分析。对盂肱关节的尺寸和方向进行了 3 维分析。评估盂肱关节尺寸各参数之间的性别差异和相关性。结果：正常日本肱骨头平均宽度为41.4毫米，厚度为13.2毫米，直径为42.9毫米，后倾32度，倾斜135度。关节盂平均高度为31.5毫米，宽度为23.1毫米，直径为62.0毫米，后倾0度，下倾2度。男性和女性的盂肱关节尺寸值一致，并且男性的肱骨头和关节盂大于女性。两侧盂肱骨大小具有良好的相关性，并且身高、肱骨长度、肱骨头大小和关节盂大小之间存在直接相关性。结论：本研究揭示了正常日本人群的盂肱骨几何形状。目前的结果将有助于确定植入物的尺寸并改进反映亚洲盂肱关节正常解剖结构的肩假体的设计。 (C) 2016 年肩肘外科杂志董事会。
Background: An understanding of normal glenohumeral geometry is important for anatomical reconstruction in shoulder arthroplasty. Unfortunately, the details of the glenohumeral joint in Asian populations have not been sufficiently evaluated. The purpose of this study was to evaluate the 3-dimensional geometry of the glenohumeral joint in the normal Japanese population and to clarify its morphologic features.Methods: Anthropometric analysis of the glenohumeral joint was performed using computed tomography scans of 160 normal shoulders from healthy Japanese volunteers. The glenohumeral dimensions and orientation were analyzed 3-dimensionally. Sex differences and correlations between sides and among the respective parameters in the glenohumeral dimensions were evaluated.Results: The normal Japanese humeral head has an average width of 41.4 mm, thickness of 13.2 mm, diameter of 42.9 mm, retroversion of 32 degrees, and inclination of 135 degrees. The glenoid has an average height of 31.5 mm, width of 23.1 mm, diameter of 62.0 mm, retroversion of 0 degrees, and inferior inclination of 2 degrees. The values of the glenohumeral dimensions were uniform in men and women, and the humeral head and glenoid were larger in men than in women. The glenohumeral size was well correlated between the 2 sides, and there were direct correlations among the heights, humeral length, humeral head size, and glenoid size.Conclusions: The present study revealed the glenohumeral geometry in the normal Japanese population. The present results would be useful to determine the size of implants and to improve the design of shoulder prostheses that reflect the normal anatomy of the Asian glenohumeral joint.
