Elbow, Wrist & Hand

What It Is

An interphalangeal joint dislocation happens when an injury to the hand forces the bones of a finger joint out of position. It most often affects the middle joint of the finger (the proximal interphalangeal, or PIP, joint), which is the most commonly dislocated finger joint, but it can also affect the joint nearest the fingertip (the distal interphalangeal, or DIP, joint) (Borchers and Best, 2012). It usually results in a very painful, bruised and swollen joint that does not move properly, if it moves at all. A sprain is different: it is an injury to the ligaments (the tough bands that hold the two bones together) without the joint coming out of place (East Kent Hospitals University NHS Foundation Trust, 2026).

A suspected dislocation needs to be checked and treated as quickly as possible (Borchers and Best, 2012). Some people try to pull the finger back into place themselves, but this should only be done by a medical professional, because the finger needs an X-ray to check for a broken bone (Borchers and Best, 2012). Finger joint injuries usually happen when the finger is forced backwards or sideways past its normal limits (East Kent Hospitals University NHS Foundation Trust, 2026), for example during a twisting injury, a fall or sport. Common sports are contact or combat sports, or snow sports.

Interphalangeal Joint Dislocation Anatomy

The anatomy of the hand is complex and intricate, and a healthy hand is essential for everyday activities. Hands can be affected by many disorders, but often by a traumatic injury.

There are 27 bones in the hand. Eight small bones, called the carpals, are in the wrist. The palm contains five bones, called the metacarpals. The 14 bones in the fingers and thumb are called the phalanges. The interphalangeal joints are the joints between the phalanges.
