Shoulder Injuries

The Shoulder joint is a highly mobile but very unstable joint, and therefore prone to injury. The shoulder itself is a grouping of bones and articulations; the humerus bone from the arm, the scapula or shoulder blade, the clavicle and the sternum or breast bone. When ever the arm is being moved these bones are moving. There are a series of muscles that over lap the shoulder joint. The most visible being the deltoid muscles which are compromised of the anterior, medial and posterior muscles. Also important are the rotator cuff muscles; teres minor, sub scapularis, infraspinatus and supraspinatus.
