subluxation vs. dislocation

subluxation vs. dislocation: What's the difference?

Subluxation and dislocation refer to types of joint injuries. A subluxation occurs when two adjoining bones get pulled partially out of position, but still touch. A dislocation occurs when they no longer touch. In the shoulder, for example, a subluxation would occur when the arm was partially out of its socket, and a dislocation when it was fully out of its socket.
