An algorithm for successfully managing anterior shoulder instability.

Abstract

The most common form of shoulder instability involves the anterior glenohumeral joint. Often it is associated with labral and bony injuries with subsequent recurrent instability. To determine optimal management, clinicians should perform a detailed history and physical examination, including appropriate diagnostic imaging to assess for concomitant humeral and glenoid bony deficiencies and other soft-tissue pathologies. Early surgical intervention may reduce risk of recurrence, particularly in young, active athletes. This article highlights the relevant anatomy, pathoanatomy, diagnostic examination including radiologic imaging, management, and prevention of complications for anterior shoulder instability. Minimizing recurrence is key to restoring function for patients to safely return to recreational and sporting activities, and to perform activities of daily living.
