Abstract
The shoulder joint is effective at five different places (1) The gleno—humeral joint. (2) the sub—acrornial joint. (3) the acrornio—clavic-ular joint. (4) the sterno— clavicular joint. (5) the movement of the scapula across the thoracic wall.
In additior to the movement at the gleno—humeral joint,
the following movements take place during various phases of elevation of the shoulder.
The first phase in which elevation of the shoulder to 30 degrees in abduction, there is elevation of the outer end of the clavicle by about 12—15 degrees, irrigular rotation of the scapula through an antero—posterior axis with no significant rotation of the scapula round of a vertical axis through the acromio—clavicular joint leading to increase the angle between the scapular spine and clavicle by about lo degrees.
The second phase in which elevation of the shoulder from 30—90 degrees of abduction, there is further elevation of the outer end of the clavicle to its final position and for each 10 degrees of glenohumeral movement 5 degrees of rotation of the scapula in the antero—posterior axis takes place.
The third phase in which elevation of the shoulder over the head from the end of the second phase, there is the same.
