It provides more motion than any other joint in the human body, yet the humeral head (ball of the shoulder joint) remains precisely centered in the glenoid (the socket of the joint) throughout the wide range of shoulder activities. One of the main stabilizing mechanisms is concavity compression, in which the head of the humerus is held into the glenoid concavity by the action of the rotator cuff (much like a golf ball is held into the concavity of a golf tee). The figure shows the humeral head, the glenoid, and one of the muscles of the rotator cuff. The concavity of the shoulder socket is deepened by a fibrous ring, known as the glenoid labrum (see movie 1). The glenoid labrum greatly increases the stability of the shoulder (see movies 2 and 3). Another stabilizing mechanism is ligament restraint in which the motion of the shoulder is kept within the proper range by ligaments that span
