Finger Dislocation: Symptoms & Signs

Medically Reviewed on 1/13/2022

A finger dislocation occurs when any of the joints involving the finger bones become dislocated from each other. Finger dislocations occur at the joints within the finger: metacarpal phalangeal (MCP), proximal interphalangeal (PIP), and distal interphalangeal (DIP).

Finger dislocations are typically very painful. Signs and symptoms in addition to finger pain can include a

  • crooked or deformed finger that is bent upward or at strange angles,
  • inability to bend or straighten the finger,
  • swelling, and
  • bruising.

Numbness and tingling can be present if there is associated damage to the nerves in the finger.
