Type IV SLAP Tear of the Left Labrum
This exhibit depicts the anterior anatomy of the glenohumeral joint with a type IV SLAP tear of the labrum. Anatomical structures include: the acromion process, clavicle, coracoid process, glenoid cartilage, glenoid labrum, long head of the biceps brachii, supraspinatus, humeral head, and scapula. The glenoid labrum is a fibrocartilagenous rim of tissue that provides stability to the shoulder socket and serves as the insertion site for the long head of the biceps brachii. There are four classifications of labral injuries known as SLAP tears (SLAP I-IV). SLAP is an acronym representing "Superior Labral tear from Anterior to Posterior." A SLAP IV tear is a bucket-handle tear of the superior labrum, with extension of the tear into the biceps tendon.
