The labrum lines the glenoid creating a rim that deepens the glenoid cavity aiding in keeping the humeral head in the joint. Labral tears are commonly associated with dislocation of the shoulder, these tears are referred to as Bankart lesions. Bankart lesions indicate a tear at the anterior to inferior portion of the labrum. A reverse Bankart lesion would refer to a posterior to inferior tear of the labrum. The superior portion of the labrum can also be torn indicating a SLAP tear.
Labral tears can be treated with an arthroscopic repair that involves securing the labrum back to the glenoid and tightening the joint capsule if necessary.
