假设：本研究的目的是研究肾盂和肩关节平面的三维(3-D)方向。我们使用了不同的定义和测量了不同的平面，我们假设变化最小的三维平面最适合定义最可靠的关节平面。方法：我们研究了来自18-80岁患者的150例非病变肩关节的CT扫描。测量肩胛骨平面和5个不同的肾盂平面：下、前、后、上和中立面。所有的平面版本和倾斜角都被测量。由于所有检查都是在一个标准化的位置上进行的，所以可以相对于身体的冠状面、矢状面和横断面来确定肩胛骨平面。结果：下关节突平面的标准差(平均值为3.76)显著低于前(P<；.001)、后(P=.001)和上(P=.001)关节突平面(ANOVA)。对于倾斜度，所有平面都有类似的变化。肩胛骨平面在性别之间存在差异(P=0.022)，并且与年龄相关。结论：本研究表明下关节突的后移是合理的恒定的。肩关节下部的骨人体测量可以提供一个可重现的参考点，用于肩部的假体外科。证据水平：II级；基础科学研究；解剖学调查(C)2010年肩肘外科理事会期刊。
Hypothesis: The purpose of this study was to investigate the 3-dimensional (3-D) orientation of the glenoid and scapular planes. Different definitions of the glenoid plane were used and different planes measured, and we hypothesed that the 3-D plane with the least variation would be best to define the most reliable glenoid plane.Methods: We studied 150 CT scans from nonpathological shoulders from patients between 18 and 80. The scapular plane and 5 different glenoid planes were determined: inferior, anterior, posterior, superior, and neutral. All plane versions and inclination angles were measured. Because all examinations were done in a standardized position to the coronal, sagittal, and transverse planes of the body, the scapular plane could be defined versus the coronal, sagittal, and transverse planes of the body.Results: The version (mean, 3.76) of the inferior glenoid plane showed a significantly lower standard deviation than the version of the anterior (P < .001), posterior (P = .001), and superior (P = .001) glenoid plane (ANOVA). For inclination all planes have a similar variance. The scapular plane was different between gender (P = .022) and correlated with age.Conclusion: This study showed that the retroversion of the inferior glenoid is reasonably constant. The osseous anthropometry of the inferior glenoid can offer a reproducible point of reference to be used in prosthetic surgery of the shoulder.Level of evidence: Level II; Basic Science Study; Anatomical Survey (C) 2010 Journal of Shoulder and Elbow Surgery Board of Trustees.
