Abstract

Objective: To describe the morphology and dimensions of Hill-Sachs lesions on two-dimensional (2D) and three-dimensional (3D) computed tomography (CT) in patients with anterior shoulder instability.


Subjects and methods: A cohort study was conducted in 75 patients with traumatic anterior shoulder instability treated at Military Hospital 175 from August 2022 to December 2025. On 2D CT, lesion width, depth, Hill-Sachs angle, bicipital angle and glenoid diameter were recorded; on 3D CT, the Hill-Sachs interval, glenoid track width and on-track/off-track status were evaluated.


Results: The mean Hill-Sachs width and depth on 2D CT were 11.34 ± 3.62 mm and 6.99 ± 2.07 mm, respectively. Moderate-width lesions (10-20 mm) accounted for 58.7%, and lesions 5-8 mm in depth accounted for 60.0%. The mean Hill-Sachs angle was 27.5 ± 12.4°, the bicipital angle 125.0 ± 8.6° and the mean glenoid diameter 28.3 ± 2.1 mm. On 3D CT, the mean Hill-Sachs interval was 13.6 ± 2.8 mm and the mean glenoid track width 19.5 ± 1.9 mm; 72 of 75 patients (96.0%) had on-track and 3 (4.0%) off-track lesions.


Conclusion: Hill-Sachs lesions in this cohort were predominantly of moderate size. Combined 2D and 3D CT assessment provides complementary morphological information, and on-track/off-track classification is useful for evaluating potential engagement and treatment planning.
