Sex differences in shoulder acromiohumeral contact surface arc length on three-dimensional computed tomography imaging.

ABSTRACT: Anatomy-based guidelines for shoulder surgery have established the routine preoperative evaluation of the humeral head. Despite recognized sex differences in humeral head size, there has been limited investigation into sex-specific variations in acromiohumeral contact surface (AHCS) arc length. This study aims to assess sex differences in the AHCS arc length within a sample of the Chinese population. We retrospectively analyzed 169 normal shoulder CT images from a single medical center, collected between 2011 and 2021. The AHCS arc length was defined as the distance from the superior glenoid tubercle to the lateral edge of the greater tuberosity, measured using a three-dimensional reconstruction algorithm. Physiological reference values for the AHCS arc length were determined at three abdu
