PURPOSE
To evaluate the glenoid shape and to evaluate if the contralateral glenoid can be used as size reference.
METHODS
Two independent investigators prospectively analysed shoulder computer-tomographies of 90 patients. The glenoids were positioned in a true "en face" view and evaluated for size and shape. The intraindividual correlation of these parameters between left and right side were assessed.
RESULTS
In the 90 computer tomographically evaluated shoulder pairs a significant intraindividual correlation of size and shape was seen (P < 0.001). The intraindividual difference in glenoid surface area averaged 1.8% of the total glenoid surface. The shape of the inferior hemisphere correlated 100%. We found all the inferior glenoids to be circular.
CONCLUSION
Our study clearly shows that the inferior glenoid in healthy individuals has the shape of a circle. The high side-to-side correlation of the glenoid surface area can be applied when measuring bony defects by evaluation of the contralateral side.
目的
评估肩胛盂的形状，并评估对侧肩胛盂是否可作为尺寸参考。
方法
两名独立研究者前瞻性分析了90例患者的肩部计算机断层扫描图像。将肩胛盂置于真正的“正位”视图中，评估其尺寸和形状。评估这些参数在左右两侧之间的个体内相关性。
结果
在90对经计算机断层扫描评估的肩部中，观察到尺寸和形状存在显著的个体内相关性（P < 0.001）。肩胛盂表面积的个体内差异平均为肩胛盂总表面积的1.8%。下半球的形状相关性为100%。我们发现所有下肩胛盂均为圆形。
结论
我们的研究清楚地表明，健康个体的下肩胛盂呈圆形。在通过评估对侧来测量骨缺损时，肩胛盂表面积的高左右相关性可被应用。
