Dislocation of a joint occurs when traumatic forces cause complete loss of continuity between the jointâ€™s 2 articulating surfaces. Subluxation, on the other hand, occurs when the loss of continuity between the joints is only partial. A dislocation may or may not involve a fracture. Dislocations of the finger joints involve either the interphalangeal (IP) joint or the metacarpophalangeal (MCP) joint.
