During glenohumeral arthroplasty, not only should the dimensions of the prosthesis match the normal anatomy but also the relationship of the humeral head-greater tuberosity and humeral head inclination should be replicated to avoid muscular dysfunction. To date there is no evidence whether fit could be optimized with gender-specific prostheses.
Magnetic resonance (MR) arthrography imaging was used to evaluate 81 proximal humeral scans for 5 different anatomic parameters. The study group included 41 men and 40 women, aged 20 to 62 years. Anatomic parameters, including the humeral head height, humeral head width, humeral head-greater tuberosity distance, humeral head inclination, and glenoid version were measured using Horizon Rad Station 11.0 to evaluate the MR imaging.
The humeral head height, width, and distance to the greater tuberosity were significantly different in size between genders. However, none of the anatomic relationships were different. The humeral head-greater tuberosity distance significantly correlated with the humeral head inclination in both men (r = 0.338; P < .05) and women (r = 0.448; P < .005).
We conclude that there are no significant differences in glenohumeral relationships between genders.
在肩关节置换术中，不仅假体的尺寸应与正常解剖结构相匹配，而且还应复制肱骨头-大结节和肱骨头倾斜的关系，以避免肌肉功能障碍。迄今为止，尚无证据表明性别特异性假体是否可以优化拟合。
磁共振（MR）关节造影成像用于评估 5 个不同解剖参数的 81 个近端肱骨扫描。研究组包括 41 名男性和 40 名女性，年龄 20 至 62 岁。使用 Horizon Rad Station 11.0 测量解剖参数，包括肱骨头高度，肱骨头宽度，肱骨头-大结节距离，肱骨头倾斜度和关节盂版本，以评估 MR 成像。
男女之间的肱骨头高度，宽度和距大结节的距离在尺寸上有明显差异。但是，没有任何解剖关系不同。男女两性的肱骨头-大结节距离与肱骨头倾斜度均显着相关（男性 r = 0.338； P <.05；女性 r = 0.448； P <.005）。
我们得出的结论是，男女之间的肩肱关系没有显着差异。
