Coracoglenoid angle was measured as the angle between the line tangential to the glenoid rim and the line projecting from the anterior edge of the glenoid to the coracoid tip on the axial image. First, a line is drawn tangential to the glenoid rim. Second, another line is formed by connecting the anterior edge of the glenoid to the coracoid tip. Asterisk shows the coracoglenoid angle as the angle between the first and second lines.
