摘要Introduction: This study aims to describe the glenoid anatomy in the Southern Chinese population.

Methodology: Plain CT-scans of the shoulder taken from 2012 to 2018 were analysed. The glenoid shape was classified into ‘pear’, ‘elliptical’ and ‘inverted pear’. The axial configuration of the glenoid was classified into ‘posterior-prominent’, ‘neutral’ and ‘anterior-prominent’. The maximum glenoid widths and heights were measured. The glenoid version was calculated using the trans-scapular axis as reference. Bone defect, if present, was quantified using the ‘best fit circle’ method. Data were analysed using the SPSS system.

Results and Analysis: 212 patients were included. 83.5% of glenoids were pear-shaped while 16.9% were elliptical. 94.8% of glenoids had posterior-prominent axial configurations while 5.2% had neutral axial configurations. None of the glenoids were inverted pear in shape or had anterior-prominent axial configuration. The mean maximum glenoid height was 32.75mm. The mean maximum glenoid width was 26.87mm. 57.5% of the glenoids were anteverted. The mean angle of version was 2.78 degrees anteversion. 4 glenoids had bone defects. There were statistically significant differences in the mean heights, widths and versions between genders.

Discussion and Conclusion: Similar to previous studies, majority of glenoids were pear-shaped. The mean maximum
glenoid width in our study was within the range reported from prior studies, while the mean maximum glenoid height was smaller. The mean glenoid version in our study was more anteverted. The glenoid anatomy in the Southern Chinese population is unique and may have implications in implant design and surgical planning.
