The shoulder joint is a ball-and-socket joint and is the most
freely moving joint of the body. The shoulder joint can move in
multiple directions therefore it is less stable than other joints
and is more susceptible to injury. Dislocation of the shoulder
joint is common and occurs when the top part of arm bone slips out
of its socket.
