Anterior Shoulder Instability

Excerpt

Glenohumeral instability encompasses both dislocation and subluxation events, and instability events commonly affect the general population. Approximately 1% to 2% of the general population will experience a glenohumeral dislocation in their lifetime. The young, active, athletic population is particularly susceptible to shoulder instability events. Over 95% of shoulder instability events occur in the anterior direction.

Over the last few decades, the knowledge regarding the risk factors, diagnosis, nonoperative and surgical management, and rehabilitation principles has continued to improve, permitting clinicians to optimally manage shoulder instability patients. A comprehensive history, clinical exam, diagnostic imaging studies, and accurate characterization of each patient’s instability pattern will help healthcare providers properly treat and manage each patient appropriately.
