The human shoulder is made up of three bones: the clavicle (collarbone), the scapula (shoulder blade), and the humerus (upper arm bone) as well as muscles, ligaments and tendons. The articulations between the bones of the shoulder make up the shoulder joints.
The shoulder must be mobile enough for the wide range actions of the arms and hands, but stable enough to allow for actions such as lifting, pushing and pulling. The compromise between mobility and stability results in a large number of shoulder problems. This instability increases the likelihood of joint injury, often leading to a degenerative process in which tissues break down and no longer function well. Major injuries to the shoulder include rotator cuff tear and bone fractures of one or more of the bones of the shoulder.
