Dislocations can occur in contact sports, such as football and hockey, and in sports that may involve falls, such as downhill skiing, gymnastics and volleyball. Basketball players and football players also commonly dislocate joints in their fingers and hands by accidentally striking the ball, the ground or another player.

A hard blow to a joint during a motor vehicle accident is another common cause of dislocation, as is landing on an outstretched arm during a fall.
