An understanding of the morphology of the glenoid is important from the viewpoint of implant design and selection. This study describes the endosteal dimensions and shape of the glenoid and correlates these results with age, gender, and the presence of osteoarthritis. This study used 72 scapulae. Data were obtained from computed tomography scans of both cadaveric and in vivo glenoids. The glenoid is relatively straight-sided in the coronal plane and more highly fluted in the transverse plane. The endosteal dimensions were larger for male specimens, but there was no difference in endosteal shape with respect to gender. These findings were not influenced by age or the presence of osteoarthritis. This study suggests that traditional glenoid component designs may not be optimal. To maximize fixation, a rectangular keel may be most effective in the coronal plane and a triangular keel may be most effective in the transverse plane.
从植入物设计和选择的角度来看，了解肩胛盂的形态很重要。本研究描述了肩胛盂的骨内膜尺寸和形状，并将这些结果与年龄、性别和骨关节炎的存在情况相关联。本研究使用了72块肩胛骨。数据来自尸体和活体肩胛盂的计算机断层扫描。肩胛盂在冠状面相对较直，在横切面有更多的沟纹。男性标本的骨内膜尺寸更大，但骨内膜形状在性别方面没有差异。这些发现不受年龄或骨关节炎存在情况的影响。本研究表明，传统的肩胛盂组件设计可能不是最佳的。为了最大限度地实现固定，矩形龙骨在冠状面可能最有效，而三角形龙骨在横切面可能最有效。
