Abstract :Purpose: The aim of this study is to determine the normal reference values for natural glenoid version, scapulothoracic angle, and scapular inclination angle in a healthy population, and to assess whether these parameters vary according to age and gender. Materials and Methods: This study was conducted on 120 healthy adult subjects (58 females, 62 males) aged 21 to 75 years, using Computed Tomography (CT). The participants were divided into two primary groups based on gender (female and male), and further categorized into six age-based groups. Five parameters were evaluated in total. The glenoid version was measured at three levels: middle (GVM), below (GVB), and above (GVA) the glenoid. Results: The mean ages of the female and male participants were 51.54 ± 20.16 years and 49.60 ± 18.82 years, respectively. The GVA, GVM, GVB, SIA, and STA were found as 5.53°±8.01°, -0.02°±5.08°, 1.37°±5.03°, 47.03°±9.42°, and 41.30°±9.55° in females, respectively. The same dimensions were -4.25°±8.62°, -0.53°±5.49°, -0.02°±5.57°, 44.90°±8.40°, and 44.82°±9.19° in males, respectively. Post hoc test demonstrated that the SIA and STA values showed significant differences across age groups 1 to 6. Conclusion: This study provides data that may serve as a reference for distinguishing between normal and pathological anatomy, while also offering essential anatomical and radiological parameters that will enable clinicians particularly radiologists and orthopedic surgeons to assess, reconstruct and design this anatomical structure.
