Management of Shoulder Instability in 2020: What, When, and How.

ABSTRACT

Anterior glenohumeral instability remains a common clinical problem in the athletic and working patient populations, and further, recurrence rates following stabilization surgery continue to be problematic. Over the past 5 years, there have been substantial improvements in the understanding of anterior shoulder instability. To better counsel and treat patients, it is imperative for surgeons to have a comprehensive understanding of the epidemiology of shoulder instability, the anatomy of the glenohumeral joint particularly as it relates to glenoid and humeral head bone loss, surgical indications, and surgical techniques. These critical topics are summarized in an effort to provide a complete guide to managing anterior shoulder instability in 2020.
