The reason why the shoulder joint can be dislocated forward is that there must first be violence that causes a tear in the soft tissue beneath the front of the shoulder joint, that is, a tear in the labrum of the shoulder glenoid and the glenohumeral ligament that connects the labrum to the humeral head. Therefore, without proper treatment, the torn soft tissue barely heals in its original position (i.e., out of place), does not heal at its original length (i.e., slackens), or not only does not heal, but even absorbs and disappears. This detachment and loss of soft tissue cannot maintain the humeral head in the shoulder glenoid fossa, and when the shoulder joint is subjected to similar dislocation violence again, the humeral head will be dislocated again. Today I will show you the glenoid and glenohumeral ligament tear that I saw during surgery last week. In the picture you can see that the glenoid labrum has dislocated and partially absorbed, becoming very small, and the glenohumeral ligament has moved away from the shoulder glenoid and will not return to its original position without sutures.
