The shoulder is the multi-jointed structure which combines tendons and muscles so as to allow different degrees of motion in the arm. The most mobile joint in the body is shoulder joint. All the forward and backward movements, circular motions, upward movements and downward movements are governed by the mobility of joint. The mobility of the joint is accompanied by natural wear and tear of the joint.

Let us take a brief glimpse at the anatomical position of the shoulder joint. The shoulder joint is a beautifully placed ball-and-socket joint having three pillar bones: long arm bone (Humerus), collarbone (Clavicle) and shoulder blade (Scapula).A layer of cartilage provides a cushioning support to these three pillar bones. The Atrioventricular joint is the first joint placed between the scapula and the clavicle. The glenohumeral joint is the second joint placed between ball-shaped part of the Humerus bone and the scapula bone’s outer edge. This second joint is called as shoulder joint.

The Rotatory Cuff is the life of the shoulder. The rotator cuff helps in allowing different degrees to the joint. Four tendons make this solid rotator cuff. Tendons connect muscles to the bone as we all know. A damage or injury to the tendons or bones surrounding the rotator cuff makes movement of shoulder joint difficult accompanied by a pain or a swelling in some cases.
