Axial coracoacromial inclination-glenoid version (CA-GV) difference was measured as the angle between the line connecting the axial projection of acromion tip and coracoid tip and the line drawn tangential to the glenoid rim on the axial image. The repoints are used to figure axial projection of the acromion at the level of the coracoid tip. First, a line is drawn from the tip of projected acromion to the coracoid tip. Second, another line is drawn tangential to the glenoid rim. Asterisk is the angle between the first and second lines as the axial coracoacromial inclination-glenoid version difference.
