Recurrent Posterior Shoulder Instability: Diagnosis and Management

Posterior shoulder instability is a relatively rare condition and surgical challenge. Arthroscopic techniques have allowed for improved diagnosis and management of this condition. The purposes of this report are to outline the problem of posterior shoulder instability, review the biomechanics and relevant pathoanatomy, and describe our preferred surgical technique. Our results of arthroscopic treatment of posterior instability will also be discussed and pearls for operative success highlighted.
