Arthroscopic repair of posterior bony Bankart lesion addresses glenoid capsulolabral pathology

Posterior instability is less common than anterior shoulder instability, encompassing approximately 10% of all shoulder instability in young active patients. The etiology of posterior instability is most commonly traumatic dislocation or subluxation that damages the posterior labrum, posterior inferior glenohumeral ligament, and/or the bony glenoid rim (posterior bony Bankart lesion)
