Shoulder dislocation and subluxation injuries are common in young athletes and most frequently occur during the competitive season. Controversy exists regarding optimal treatment of an athlete with an in-season shoulder dislocation, and limited data are available to guide treatment. Rehabilitation may facilitate return to sport within 3 weeks, but return is complicated by a moderate risk of recurrence. Bracing may reduce the risk of recurrence, but it restricts motion and may not be tolerated in patients who must complete certain sport-specific tasks such as throwing. Surgical management of shoulder dislocation or subluxation with arthroscopic or open Bankart repair reduces the rate of recurrence; however, the athlete is unable to participate in sport for the remainder of the competitive season. When selecting a management option, the clinician must consider the natural history of shoulder instability, pathologic changes noted on examination and imaging, sport- and position-specific demands, duration of treatment, and the athlete's motivation.
