As a ball and socket joint, the shoulder is incredibly mobile and allows arm movement in many directions. As such, it is inherently unstable, and thus is prone to dislocation. When the shoulder is dislocated, the head of the humerus is removed from its socket in the glenoid fossa. The shoulder may dislocate in various directions.
