Abstract

Posterior shoulder instability (PSI) is a shoulder pathology that is challenging to diagnose, leading to 
treatment delay and exacerbation of symptoms. Etiology can be both traumatic and atraumatic, and a 
comprehensive clinical history plays a significant role in achieving diagnosis. Imaging in the setting of 
PSI can reveal a reverse-Bankart lesion, a reverse Hill-Sachs lesion, posterior labral cysts, and 
potentially glenoid or lesser tuberosity fractures. Both conservative and surgical options exist for 
patients with PSI, and management often depends on case severity, extent of bone loss, and patient 
goals and expectations. Holistic patient education regarding the etiologies, mechanisms and possible 
treatment options available is pivotal for achieving high levels of patient satisfaction and optimal 
outcomes.
