ANATOMY OF THE SHOULDER
The shoulder is made up of three bones: the clavicle (collarbone), the scapula (shoulder blade), and the humerus (upper arm bone) as well as associated muscles, ligaments and tendons. The articulations between the bones of the shoulder make up the shoulder joints. The joint cavity is cushioned by articular cartilage covering the head of the humerus and face of the glenoid. The joint is stabilized by a ring of fibrous cartilage surrounding the glenoid called the labrum.
Four short muscles originate on the scapula and pass around the shoulder where their tendons fuse together to form the rotator cuff. Two bursae cushion and protect the rotator cuff from the bony arch of the acromion and allow smooth movement of the joint- subacromial bursa and subdeltoid bursa.
JOINTS OF THE SHOULDER

DEFINITION OF FROZEN SHOULDER
Frozen shoulder, medically referred to as adhesive capsulitis, is a disorder in which the shoulder capsule, the connective tissue surrounding the glenohumeral joint of the shoulder, becomes inflamed and stiff, and grows together with abnormal bands of tissue, called adhesions, greatly restricting motion and causing chronic pain. A frozen shoulder is a shoulder joint with significant...
