Shoulder dislocations occur more often than dislocations in any other major joint. The shoulder can dislocate forward, backward, or downward. In a typical case of a dislocated shoulder, a strong force that pulls the shoulder outward (abduction) or extreme rotation of the joint pops the ball of the humerus out of the shoulder socket. Dislocation commonly occurs when there is a backward pull on the arm.
