Shoulder disorders are some of the most common joint complaints, and shoulder impingement syndrome and rotator cuff tendonitis are considered to be the most frequent cause of shoulder pain and disability. The shoulder complex is unique in the body due to its structure and function. It is considered a ball and socket joint involving the large rounded end of the upper arm bone called the humerus and the small shallow socket of the shoulder blade. This disproportional shape allows for a wide range of directions that the arm can be moved; however, it does not provide much stability to hold it in place. The stability of the shoulder relies heavily on numerous ligaments, tendons and muscles; and the most common group is called the rotator cuff. The rotator cuff attaches to and surrounds the rounded end of the humerus and is bordered superiorly by a bony roof called the acromion. There is a small space between this bony roof and the rotator cuff. With reaching overhead, the space around the rotator cuff decreases, sandwiching and pinching the tendons between the two bones. This can lead to the disorder of shoulder impingement where the tendons become compressed and then inflamed.
