Finger dislocation, also called a finger jam, is a common injury. It occurs when the bones of the finger are moved (dislocated) from their normal position. A dislocated finger can occur in any of the joints of any finger, but it occurs most often in the middle knuckle of the little, ring, middle, or index finger.
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.
