Due to the difference in size between the humeral head and the glenoid, the shoulder joint is prone to instability. Therefore, the reconstruction of the physiological joint morphology is of great importance in shoulder joint preservation and replacement surgery. The aim of this study was to describe physiological reference parameters for the morphology of the glenoid for the first time.
MRI images of the shoulder joints of 418 patients (mean age: 50.6 years [± 16.3]) were retrospectively analysed in a low-grade osteoarthritic population. The glenoid distance in coronal (GDc) and axial view (GDa), glenoid inclination (GI) and version (GV) as well as scapula neck length (SNL) were measured. Parameters were studied in association for age, gender, side and degeneration grade.
Mean GDc was 33.4 mm (± 3.6), mean GDa 26.8 mm (± 3.2), mean GI 10.5° (± 6.4), mean GV -0.4 mm (± 5.4) and mean SNL was 33.4 mm (± 4.7). GDa was significant higher in right shoulders (p < 0.001). GDc and GDa showed significant higher mean values in older patients (p < 0.001) and in shoulders with more severe degenerative changes (p < 0.05). While GDc, GDa and SNL were significant larger in male patients (p < 0.001), GI had a higher mean value in female shoulders (p = 0.021).
Age, gender and shoulder joint degeneration influence changes in the morphological parameters of the glenoid. These findings have to be considered in shoulder diagnostics and surgery.

由于肱骨头与关节盂大小存在差异，肩关节易于出现不稳定。因此，在肩关节保留和置换手术中，重建生理关节形态至关重要。本研究的目的是首次描述关节盂形态的生理参考参数。
对418例（平均年龄：50.6岁[±16.3]）低度骨关节炎患者的肩关节MRI图像进行回顾性分析。测量关节盂在冠状面（GDc）和轴位（GDa）的距离、关节盂倾斜度（GI）和扭转度（GV）以及肩胛颈长度（SNL）。研究这些参数与年龄、性别、患侧及退变程度的相关性。
平均GDc为33.4毫米（±3.6），平均GDa为26.8毫米（±3.2），平均GI为10.5°（±6.4），平均GV为-0.4毫米（±5.4），平均SNL为33.4毫米（±4.7）。右肩关节的GDa显著更高（p<0.001）。GDc和GDa在老年患者（p<0.001）以及退变更严重的肩关节（p<0.05）中显示出显著更高的平均值。虽然男性患者的GDc、GDa和SNL显著更大（p<0.001），但女性肩关节的GI平均值更高（p=0.021）。
年龄、性别和肩关节退变会影响关节盂形态参数的变化。在肩关节诊断和手术中必须考虑这些发现。
