What It Is

A finger dislocation is when the bones of a finger joint are pushed out of their normal position. It happens when an injury tears or stretches the ligaments that hold the joint together, usually when the finger is forced backwards or sideways past its normal limits (East Kent Hospitals University NHS Foundation Trust, 2026). The finger will be deformed, swollen and painful. The middle joint of the finger (the PIP joint) is the most commonly dislocated joint in the body (Leggit and Meko, 2006a). Sport is a common cause: high-impact sports such as rugby and American football, as well as sports that involve catching fast balls, such as cricket.

It can be hard to tell whether a finger is broken, dislocated or badly sprained, so you will probably need an X-ray (NHS, 2025).

Finger Dislocation Anatomy

All of the fingers have three bones in them, while the thumb only has two bones. At each joint, the bones are held together by ligaments, which are tough bands of connecting tissue (East Kent Hospitals University NHS Foundation Trust, 2026). There is a collateral ligament on each side of the joint, and a thick ligament on the palm side called the volar plate. In the most common type of dislocation, where the finger is bent backwards, the volar plate is injured and the collateral ligaments are often damaged too. Injuries that force the finger sideways tear the collateral ligaments (Leggit and Meko, 2006b). The muscles that move the fingers are in the forearm and hand. They turn into tendons, which attach the muscles to the finger bones, and the muscles move the fingers by pulling on the tendons. The finger bones join the five metacarpal bones that make up the palm of the hand.
