The area of the body where the arm attaches to the trunk.Three bones meet here: the scapula, clavicle, and humerus. The ball-and-socket joint at the shoulder has a wide range of movement. Common injuries include dislocation (see shoulder, dislocation of) and fractures of the clavicle or upper humerus. The shoulder may be affected by any joint disorder, which in severe cases may lead to frozen shoulder. Inflammation of a tendon or a bursa around a shoulder joint can cause painful arc syndrome.
