Data regarding the parameters of the coracoid process and glenoid width are insufficient, and information on gender, age, and ethnic differences in the parameters appear lacking in the Chinese population. This study aimed to investigate the morphometric parameters in the coracoid process and glenoid width.
Using our institution's electronic database, we selected 84 patients (55 males and 29 females) who underwent a shoulder computed tomography (CT) scan from January 2017 to May 2018 in this study. Mimics19.0 software was used for three-dimensional (3D) reconstruction of CT and to measure the morphometric parameters of the coracoid process and glenoid width. Subgroup analyses stratified by gender and age were conducted and the parameters were compared with previously published reports. All data were statistically analysed by SPSS23.0 Statistical Package.
A positive and significant relationship between the coracoid process and the glenoid width (R > 0.758, P < 0.01) was found. The midpoint width represents 52% (41-62%) of the glenoid width; the midpoint height, 40% (31-53%) of the glenoid width. Significant differences in all parameters between males and females were noted (P < 0.05). No significant differences among the age groups were observed (P > 0.05), whereas significant differences in almost all parameters between the ethnic groups were observed (P < 0.05).
Our results could supplement the information in the shoulder joint database with morphometric parameters and provide a reference for theoretical research on coracoid osteotomy, which may in turn help surgeons in the evaluation of coracoid process transfer.
有关喙突参数和肩胛盂宽度的数据不足，并且在中国人中，有关参数的性别、年龄和种族差异的信息似乎也缺乏。本研究旨在研究喙突和肩胛盂宽度的形态学参数。
本研究使用我们机构的电子数据库，选择了 2017 年 1 月至 2018 年 5 月期间进行肩部 CT 扫描的 84 名患者（55 名男性和 29 名女性）。使用 Mimics19.0 软件对 CT 进行三维（3D）重建，并测量喙突和肩胛盂宽度的形态学参数。进行了性别和年龄的亚组分析，并将参数与以前发表的报告进行了比较。所有数据均使用 SPSS23.0 统计软件包进行统计分析。
发现喙突与肩胛盂宽度之间存在正相关关系（R > 0.758，P < 0.01）。中点宽度代表肩胛盂宽度的 52%（41-62%）；中点高度占肩胛盂宽度的 40%（31-53%）。男性和女性之间的所有参数均存在显著差异（P < 0.05）。各年龄组之间无显著差异（P > 0.05），但不同种族之间的几乎所有参数均存在显著差异（P < 0.05）。
我们的研究结果可为肩部关节数据库提供形态学参数信息，为喙突截骨术的理论研究提供参考，从而有助于外科医生评估喙突转移。
