What Stabilizes the Glenohumeral Joint? [Part 1]

The video tutorial explains the stabilization mechanisms of the glenohumeral joint, focusing on non-ligamentous methods like muscle balance and concavity compression. It reviews shoulder anatomy, including the clavicle, scapula, and humerus, and discusses how muscle mechanics and pull directions contribute to joint stability. The tutorial emphasizes the importance of balancing vertical and horizontal forces to prevent dislocation.

What are the four mechanisms that lead to the stabilization of the glenohumeral joint?
