How often do people dislocate their shoulders more than once?

Dislocations occur more often in the shoulder than anywhere else in the body. Most shoulder dislocations happen from trauma such as a motor vehicle accident, assault, or athletic injury.

Studies have shown a high recurrence rate in some individuals. A future dislocation of the injured shoulder occurs in 90 percent of young, athletic patients. Austrian doctors found that adults between the ages of 21 and 30 who play high-risk sports have the highest rate of recurrence.
