Description
The bone morphology of the greater tuberosity and lateral acromion plays a central role in subacromial impingement syndrome. Critical Shoulder Angle (CSA) and Greater Tuberosity Angle (GTA) are validated 2D measurement parameters. These markers are static and do not consider the dynamic effect of glenohumeral motion.
This study aimed to better understand biomechanics in subacromial impingement with a dynamic simulation based on a validated 3D biomechanical model coupling joint kinematics and 3D reconstructed computed tomography (CT).
