Figure 8a. (a) Anteroposterior radiograph shows a squared-off axillary scapular border (arrows). A metaglene with fixed screw angles must be placed higher than normal on the glenoid to avoid having the inferior screw extend outside the bone. (b) Anteroposterior radiograph obtained in a different patient shows the gently curving axillary border of a normal scapula (arrowheads).
