Finger dislocation is a common injury. It occurs when the bones of the finger are moved (dislocated) from their normal anatomic position. Finger dislocation can occur in any of the joints of any finger, but it occurs most often in the middle knuckle of the little (pinky), ring, middle, or index finger. These dislocations can be accompanied by a break in the bone (fracture) but frequently happen without any breaks.
Accidents can cause a "jamming" force to be applied to the end of the finger, or the finger may be forcefully overextended. Either of these situations, or a combination of both, can result in a dislocation.
A dislocated finger is usually obvious. The finger appears crooked, swollen, and is very painful. It may be bent upward or at strange angles. The person probably won't be able to bend or straighten the finger if it is dislocated.
With severe dislocations, there can be numbness or tingling.
The injured finger can appear a pale color.
The dislocation may cause a break in the skin where the injury has occurred. If this occurs, the injured person should seek medical attention immediately.
The dislocation may be accompanied by a break in the bone and will require prompt medical attention.
