The abduction external rotation (ABER) view is excellent for assessing the anteroinferior labrum at the 3-6 o'clock position, where most labral tears are located.
In the ABER position, the inferior glenohumeral ligament is stretched resulting in tension on the anteroinferior labrum, allowing intra-articular contrast to get between the labral tear and the glenoid.
The labrum is in the 3-6 o'clock position. Due to the tension by the anterior band of the inferior GHL labral tears will be easier to detect.
