Abstract
The shoulder joint is the most flexible joint of the human body. The enormous range of motion is facilitated by the sequential connection of four bones. The balanced articulation of the glenohumeral joint is provided by the rotator cuff which inserts around the humeral head fulfilling the centering function aspect of the proximal humerus over the much smaller glenoid and provides adequate force distribution during shoulder motion. Besides these osseous and muscular parts, stabilizing effects are also contributed by ligaments and the capsule-ligamentous complex. If the fine composition of bones, muscles and surrounding soft tissue is affected by any kind of injury, unbalanced motion or even instability may result. These changes may affect the biomechanics of the shoulder and alter the shoulder joint inducing loss of power and pain according to the underlaying pathology. This chapter concentrates on the physiological range of motion and the different stabilizing and anatomical aspects of the shoulder.
