Abstract

Posterior instability of the shoulder has historically been poorly recognized. This is likely in part due to the rarity of the condition, lack of awareness, and subtle imaging findings. Acute posterior dislocation has a clear clinical presentation, but is reported to be missed between 60 and 78 % on initial presentation. Recurrent posterior instability is even more challenging to diagnose because the clinical presentation is often vague and there is generally a poor awareness and understanding of the pathology. As a result, patients, especially those without a discernible inferior component of laxity, are often overlooked or misdiagnosed as having other pathology such as superior labral lesions, internal impingement, rotator cuff disease, or scapulothoracic dysfunction. However, recent advances in the concept of posterior instability have provided us with reasonable insight into the pathology, pathogenesis, diagnostic examinations, and treatment options.
