This population-based cohort tracked every first-time anterior shoulder dislocation in Olmsted County, Minnesota over a decade. It asked how often these shoulders redislocate, who needs surgery, and whether the length of immobilization or activity restriction changes the outcome.
When you counsel a young patient after a first anterior dislocation, age and activity level frame the whole conversation. Under 20 the recurrence risk is about two-thirds, and in a young athlete returning to contact sport it climbs above 80%. Over 40 it approaches zero.
The practical lever this paper identified is time. Restricting return to sport for at least 6 weeks roughly quadrupled the odds of a satisfactory result, and the authors tie this to the roughly 6 weeks capsular and ligament tissue needs to heal. Reduction technique, arm dominance, and type of immobilizer made no difference, so do not over-invest in those choices.
Finally, remember that a shoulder can feel unstable without ever redislocating: about a quarter of nonoperative patients had bothersome instability. But since no patient with instability alone wanted surgery, this data argues against routine stabilization after a first dislocation while a trial of healing and rehab is pursued.
