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?

Explain the significance of non-ligamentous mechanisms in shoulder joint stabilization.

Describe the anatomy of the clavicle and its articulations.

Discuss the importance of the humeral head and glenoid fossa in joint stability.

What is the role of the deltoid muscle in shoulder abduction?

How do the rotator cuff muscles contribute to the stability of the glenohumeral joint?

What is muscle balance and why is it important for the glenohumeral joint?

What happens when there is a muscle imbalance in the shoulder?

Define concavity compression and its role in shoulder stability.

How do the forces acting on the humerus affect its position relative to the glenoid fossa?
