The shoulder is the most mobile joint in the body with the least stability; therefore, it is one of the most frequently injured joints in the body. Ligaments connect bone to bone, and acromio clavicular ligament connects the Acromion process to the clavicle. The glenohumeral joint is where the ball (humeral head) and the socket (the glenoid) 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. Shoulder fractures commonly involve the clavicle (collarbone), humerus (upper arm bone), and scapula (shoulder blade). Given the joint's mobility, stability is mainly based … The shoulder anatomy provides mobility but leads to a relatively unstable joint, prone to subluxation and dislocation .
