“…Generally, Asians have smaller coracoid process and glenoid width dimensions than Caucasians and Africans (P < 0.05), except for the distance from the coracoid tip/base to the coracoid midpoint among Mongolian Chinese [25]; the difference could be attributed to genetic as well as environmental influence, dietary habits, and lifestyle. Interestingly, no significant difference exists about glenoid width between the present study and a previous study [37] in Switzerland cadavers, which could be explained by the study focusing on body donors with an average age of 84 years (range 60-98 years), leading to degree of glenoid wear, and small sample sizes (18 cadavers).…”

Background: Data regarding the parameters of the coracoid process and glenoid width are insufficient, and information on gender, age, and ethnic differences in the parameters appear lacking in the Chinese population. This study aimed to investigate the morphometric parameters in the coracoid process and glenoid width. Methods: Using our institution's electronic database, we selected 84 patients (55 males and 29 females) who underwent a shoulder computed tomography (CT) scan from January 2017 to May 2018 in this study. Mimics19.0 software was used for three-dimensional (3D) reconstruction of CT and to measure the morphometric parameters of the coracoid process and glenoid width. Subgroup analyses stratified by gender and age were conducted and the parameters were compared with previously published reports. All data were statistically analysed by SPSS23.0 Statistical Package. Results: A positive and significant relationship between the coracoid process and the glenoid width (R > 0.758, P < 0.01) was found. The midpoint width represents 52% (41-62%) of the glenoid width; the midpoint height, 40% (31-53%) of the glenoid width. Significant differences in all parameters between males and females were noted (P < 0.05). No significant differences among the age groups were observed (P > 0.05), whereas significant differences in almost all parameters between the ethnic groups were observed (P < 0.05). Conclusion: Our results could supplement the information in the shoulder joint database with morphometric parameters and provide a reference for theoretical research on coracoid osteotomy, which may in turn help surgeons in the evaluation of coracoid process transfer.

“…In the present study, the average glenoid cavity height and width were 35.89 mm and 25.84 mm, respectively, and the glenoid cavity height was highly correlated with the glenoid cavity width. Conversely, the glenoid cavity height and width of other populations were as follows: 39.5 and 31.0 mm in the USA [23], 41.3 and 29.4 mm in France [24], 31.5 and 23.1 mm in Japan [25], and 36.6 and 27.8 mm in Switzerland [26], respectively. Those in China were significantly different from those in other countries.…”

Background This study aimed to investigate the three-dimensional (3D) anatomical relationship between the suprascapular nerve and scapula, and the method of protecting the suprascapular nerve in reverse total shoulder arthroplasty (RTSA) Methods In the present study, 12 fresh adult cadaver shoulder specimens were dissected. X-ray and computed tomography (CT) were used to investigate the 3D scapular and suprascapular nerve images. Results The results revealed that the best fitting baseplate diameter was 24.73 ± 1.56 mm. Furthermore, the baseplate diameter correlated with the glenoid cavity width. After the osteotomy, a simulated screw placement on the baseplate was performed. The dangerous area for the posterior screw placement was at the angle between the upper edge and transverse axis exceeding 38° and between the lower edge and transverse axis exceeding 76°. The distance between the nearest point of the nerve and osteotomy plane was 15.38 ± 2.02 mm, and the angle between the projection point of the nearest point and transverse axis was 27.33 ± 7.96°, which was the dangerous area for retractor placement. The suitable angle between the superior screw and longitudinal axis was 21.67 ± 13.27°, and the suitable superior screw length was 34.66 ± 2.41 mm. Conclusion In RTSA, the baseplate size correlates with the glenoid cavity width. The relationship between the screw and suprascapular nerve and retractor placement position should be carefully considered to avoid damaging the suprascapular nerve.

“…Various researchers have performed the morphometric analysis of cavitas glenoidalis on different materials (dry bone, fresh cadaver or 3D-CT reconstruction) in different populations [7,10,18,21,22,28]. This study is a radiological study and measurements were performed through multidetector CT.…”

Background: The glenoid cavity is a sliced egg-shaped joint surface located on the lateral margin of the scapula to form the shoulder joint. Antero-superior notch affects the morphology of the glenoid cavity. Recognition of variations in shape and dimensions of the glenoid cavity is important for better comprehension of joint-associated diseases, especially in total shoulder arthroplasty procedures. The aim of this study was to perform morphometric measurements on the glenoid cavity through Multi-detector Computed Tomography images. Methods: Glenoid cavities of 391 individuals (197 males (50.4%), 194 females (49.6%)) were reviewed by using Multi-detector Computed Tomography. CT images were examined from January 2014 to April 2016 by scanning files. The average age of men was 60.28 ± 15.43, while the average age of women was 58.82 ± 16.38. The maximum length and maximum width of glenoid cavities, the width, depth and circumference at the notch level were measured, and the index value was calculated. The glenoid cavity shapes were typed as pear, inverted comma and oval type. Furthermore, metric values which provide the best differentiation between genders were found through ROC analysis. Results: The pear GC type was detected by 53.2%, inverted comma type was detected by 28.4%, and oval type was detected by 18.4%. In all of our morphometric measurements, male values were higher than female values, and there was no significant difference between them. Furthermore, significant differences were found for width at the notch level and circumference lengths between the right and left sides; however, there was not any significant difference between maximum length, maximum width, depth and the index (p<0.05). Results of ROC analysis revealed significant measurements for the maximum length and maximum width measurements of the glenoid for gender determination. Conclusions: It was reported in the literature that morphometric information of the glenoid cavity is useful to increase clinical success in case of different pathological conditions such as Bankart lesion, rotator cuff disease, and osteochondral defect. Recognition of different shapes and dimensions of the glenoid cavity is essential for the design of the glenoid component especially for total shoulder arthroplasty procedure. We
