Shoulder instability: return to play.

Shoulder instability in the competitive athlete is a relatively common problem. The etiology of glenohumeral instability that can affect the athlete runs a wide spectrum, from an isolated traumatic dislocation to repeated microtrauma or congenital laxity. Although many athletes are able to adapt to a mild laxity that might only occasionally affect them, it can be much more difficult to adapt or return to play after a dislocation or repeated subluxation episodes. This article focuses on the return to play for competitive individuals after a glenohumeral dislocation or reconstructive surgery for shoulder instability.
