Abstract
Glenohumeral joint stability requires contributions from shoulder muscular action and the glenoid labrum. This study investigated potential compensatory muscle strategies accompanying labral compromises by utilizing a customized mathematical biomechanical shoulder model. To illustrate potential shoulder muscular responses, various isometric and functional movement tasks were simulated under various labral statuses including aged, pathological, and surgically altered. Results emphasized the anisotropic compromises due to influences of aging and damage, along with the effectiveness of different surgical techniques to restore stability. These insights provide evidence to promote secondary injury prevention and refine labral management considerations relative to fundamental mechanistic bases for functional capacity.
