Left Labral Tear Variations – No Text

This exhibit depicts the normal anatomy of the glenohumeral joint, along with six labral tear variations (SLAP I-IV, Bankart tear, and posterior labral tear). Anatomical structures include: the acromion process, clavicle, coracoacromial ligament, glenoid cartilage, glenoid labrum, long head of the biceps brachii, and the humerus. There are four classifications of labral injuries known as SLAP tears. SLAP is an acronym representing "Superior Labral tear from Anterior to Posterior." A SLAP I tear consists of partial tearing and fraying of the superior labrum, without complete detachment from the glenoid rim. SLAP II tears include detachment of the superior labrum and biceps anchor from the bone. A SLAP III tear is a bucket-handle tear of the superior labrum, without detachment or tearing of the biceps tendon. SLAP IV tears are also considered bucket-handle tears, but unlike the SLAP III tears, the tear extends into the biceps tendon. A Bankart tear is a lesion of the anteroinferior labrum with detachment from the glenoid rim. Lastly, posterior labral tears are detached lesions of the posterosuperior labrum.
