Which part of the shoulder joint is particularly prone to dislocation?

The glenohumeral joint, commonly referred to as the shoulder joint, is particularly prone to dislocation due to its anatomical structure and the range of motion it allows. This joint is formed by the head of the humerus fitting into the shallow glenoid cavity of the scapula. While this design facilitates an exceptional range of motion, it also means that the joint is less stable than others with a deeper socket.

The glenohumeral joint relies heavily on soft tissues, such as ligaments and the rotator cuff muscles, for support rather than on strong bony interlocks. When excessive force is applied or when a sudden movement occurs, this joint can easily become dislocated, as the ball (humerus) can be forced out of the socket (glenoid).

In contrast, the acromioclavicular joint is more stable due to its bony structure and limited range of motion, while the sternoclavicular joint is inherently strong due to the complex nature of its support structures. The elbow joint does not directly relate to the shoulder joint and is not noted for dislocation in the same context. Thus, the unique characteristics of the glenohumeral joint make it the most susceptible to dislocation among the
