“…e similarity of the results between the studies of Shi et al and Merrill et al is remarkable. It is known that the glenoid size in the Asian population is smaller than that in the American and European counterparts [12,21,22]. Here, the age factor, the second determinant as we also noticed in our study, steps forward.…”

“…e glenoid exhibits different morphological characteristics among ethnic communities [1,10]. In a recent study by Mizuno et al [22], the glenoid morphologies of the Japanese and French individuals with similar distributions of gender and age were compared and the AP and SI diameters in the Japanese individuals were found to be 2 mm smaller. In addition, the Japanese had a mean GV of − 2.3 degrees and the French − 6.0 degrees (p > 0.05).…”

In this study, our aim was to evaluate the glenoid version, height, and width measurements based on gender, side, age, height, and hand dominance in the Turkish population using computed tomography (CT) images. Methods. In our study, CT images of 140 patients (62 females and 78 males; mean age: 39.6 years) who had no shoulder complaints were evaluated retrospectively. Glenoid version (GV), AP diameter (width), and SI diameter (height) on both shoulders were measured on the CT images. Correlations between patient gender, side, age, height, and hand dominance and the GV and size were evaluated. Results. e right shoulder had a mean GV of − 0.93 ± 7.80 degrees and the left shoulder had a GV of − 0.88 ± 6.63 degrees (p > 0.05). e mean AP diameter of the glenoid was 26.57 ± 3.02 mm in the right shoulder and 26.33 ± 3.01 mm in the left shoulder (p > 0.05). e mean SI diameter of the glenoid was 31.8 ± 3.6 mm in the right and 31.7 ± 3.3 mm in the left shoulder (p > 0.05). When men and women were evaluated in two separate groups, the GV, AP, and SI values did not exhibit a statistically significant difference between the two shoulders in both genders (p > 0.05). ere was a positive correlation between the ages and heights of the patients and the glenoid size (p < 0.05). e mean AP diameter was approximately 28 mm and the SI diameter was 34 mm in males, whereas the mean AP diameter was 24 mm and the SI diameter was 30 mm in females (p < 0.05). e GV values of the dominant shoulders were significantly more retroverted (p < 0.05). ere was a positive correlation between the ages and heights of the patients and the glenoid size (p < 0.05). Conclusion. Hand dominance had an effect on the glenoid version, while patient gender, age, and height had an effect on the glenoid size. e glenoid width in the Turkish population was similar to that of the European and American populations, and the glenoid height was similar to that of the Asian population. Our GV values were similar to those of the Asian population and more anteverted compared to the Western population. We believe that our findings will be useful in preoperative planning and in the production of implants for our population.
