Abstract
This is a survey of the functional variation of the clavicle, in particular with regard to its adaptability, the bone being an essential link in the shoulder girdle. The presence of a clavicle, and its shape, size and position are discussed from the point of view of stability and mobility, and the ré1e of the bone regarding circulation, pulmonary ventilation and muscular tension is pointed out. It is stated that the clavicle contributes significantly to the stability of the shoulder girdle, and that in man the presence of this bone represents an increase in the degree of freedom of the upper extremity mobility pattern, dependent on the transversal shape of the thoracic diameter. The precondition for the clavicle to function appropriately is that its curvature fits in with the ligamentous pull.Keywords
