II. Pathophysiology
- Superior Labrum Anterior to Posterior Tear (SLAP Lesions)
- Associated with Biceps Tenosynovitis
- Superior labrum is more weakly attached to glenoid than inferior labrum
- Posterosuperior Labral Tears
- Less common than SLAP Lesions
- Secondary to fraying related to Internal Shoulder Impingement
III. Pathophysiology: Mechanism of Injury
- Direct blow to Shoulder
- Fall on an outstretched hand
- Repetitive overhead motion
- SLAP Lesions are the most common labral injury in overhead throwing
IV. Symptoms
- Locking, catching or popping sensation felt in the Shoulder
V. Signs
- Most reliable tests for Labral Tear
- Jobe Relocation Test (Shoulder Apprehension Test)
- O'Brien Test
- Anterior Slide Test
- Bicipital Tendonitis tests (associated with SLAP Lesions)
- Speed Test
- Yergason Test
VI. Imaging: MR Arthrography of the Shoulder
- Anterior Labral Tears in adults
- Test Sensitivity: 95%
- Test Specificity: 100%
- Superior Labral Tears
- Test Sensitivity: 60%
- Posterior Labral Tears
- Test Sensitivity: 50%
