The socket of the shoulder joint is part of the scapula, and if scapular movement is not normal, then shoulder function cannot be normal.

Your shoulder is a ball-and-socket joint made up of three bones: the clavicle (collarbone), scapula (shoulder blade) and humerus (upper arm bone). The glenohumeral joint is where the ball (humeral head) and the socket (the glenoid) meet. C onse- quently, they are susceptibleto injury and de- generation. The capsule of the glenohumeral (shoulder) joint is the articular capsule of the shoulder.It completely surrounds the joint. An image depicting shoulder anatomy can be seen below. To review the anatomy of the shoulder joint and of the physiology of glenohumeral stability is essential to manage correctly shoulder instability. Several structures hold the bones together. Fibers that connect bone to muscle are called tendons. The humerus is a long bone that forms the articulations of the glenohumeral joint proximally (with the scapula), and the humeral ulnar joint and humeral radial joint distally (with the ulna and radius respectively).

The most flexible joint in the entire human body, our shoulder joint is formed by the union of the humerus, the scapula (or shoulder blade), and the clavicle (or collarbone). Under normal circumstances, we rarely stop to think about our shoulders. The acromioclavicular joint is where the acromion, part of the shoulder blade (scapula) and the collar bone (clavicle) meet.

The shoulder is a synovial articulation between the glenoid and the humeral head in which the shallow glenoid articulation is deepened an additional 50% by the fibrocartilaginous labrum that forms a rim around the perimeter of the glenoid ().Both the glenoid and the humeral head are covered by a layer of hyaline articular cartilage.
