Fig. 1From: A predictive model for the critical shoulder angle based on a three-dimensional analysis of scapular angular and linear morphometricsMeasurement of the critical shoulder angle using an anteroposterior radiograph of the shoulder. The angle is between a line connecting the inferior with the superior border of the glenoid fossa and another connecting the inferior border of the glenoid with the most inferolateral point of the acromionBack to article page
