Fig. 1

The first two rows show anthropometric data (mean values and SD) for “normal” scapulae (= statistical shape mean model; from Beeler [3]) and “B1” scapulae (according to Walch [17]) with static posterior subluxation (from Beeler [3]). The last two rows show the data of the two printed and tested models. Note the differences in posterior height of acromion and posterior coverage (6 mm higher acromion – measured as the distance between the posterolateral acromial edge and a line through the center of the glenoid drawn perpendicular to the scapular plane; and 8° less coverage – measured as an angle between a line drawn parallel to the scapular plane and a line to the posterolateral acromial edge) between a “normal” scapula and a “B1” scapula
