In regard to shape, the morphology of the normal labrum demonstrates considerable variability on standard MR images. The cross-sectional shape of the labrum is triangular in most cases (anterior, 64%; posterior, 47%), followed by rounded (anterior, 17%; posterior, 33%). However, in a minority of cases the normal labral shape can be blunted, cleaved, notched, or even flat. The anterior and inferi..

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..

Knowledge of the normal anatomy and physiology of the glenoid labrum is important for understanding the pathogenesis of labral tears. Let's see how flexible the labrum is. You might think that the labrum is rigid. Early authors thought the labrum was uniformly rigid in shape. The labrum is predominantly composed of moderately dense bundles of fibrous tissue and therefore is quite flexible. The c..

Normal Labrum and Normal Labral Variants Morphologic Appearance The long head of the biceps tendon attaches both to the superior glenoid and to the superior labrum [13], with approximately 50% of the biceps tendon fibers arising from the superior glenoid labrum and the remainder from the supraglenoid tubercle AJR 2011; 197:596–603 Labrum is predominantly composed of moderately dense bundles of f..
