Diagnosing a posterior labral tear of the shoulder can be difficult for physicians. These tears can present with a wide variety of symptoms and there are multiple physical exam tests of undetermined significance. Posterior shoulder instability is less commonly seen than anterior instability and the incidence is 2-5%.
The labrum is a fibrocartilaginous structure that helps deepen the glenoid and is involved in joint stabilization. Tears to the posteroinferior labrum occur due to tension on the posterior band of the IGHL (inferior glenohumeral ligament) during abduction and internal rotation or with compression forces. Tears to the posteroinferior portion of the labrum can lead to recurrent shoulder dislocation.
