Abstrakt		The shoulder joint is a multi axial ball and socked joint. It has three degrees of freedom and this permits movement of the upper limb with respect to the three planes in space and the three major axes. The bones involved are the roughly hemispherical of the humerus and the shallow glenoid cavitiy of the scapula, a construction which permits very considerable movemenf but reduces the security of the joint. Structurally the shoulder joint is weak, since, for such strength as it possesses, it is dependent on the support given by the muscles which surround it and not on its bony conformation or the presence of any strong ligaments. The glenoid labrum is a rim of fibrous tissue which is triangular in cross section and overlies the glenoid cavity at the rim or edge. The shoulder capsule is large, having twice the surface area of the humeral head. There are severa! bursae found in the shoulder region, and fhere are number of recesses in fhe shoulder capsule formed between glenohumeral ligaments. Each glenohumeral ligament has clinically important properties that can be characterized by the relationship of the distance befween its origin and insertion and its tension. The acromioclavicular joint is the only articulation between the clavicle and the scapula. The capsule of the acromioclavicular joint contains a diarthrodial joint incompletely divided by a disc which usualy has a large perforation in its center. The articular surfaces are covered with fibrocar- tilage. The average size of the adult acromioclavicular joint is 9 mm by 19 mm.
