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.

Causes of a Dislocated Finger

A dislocated finger is caused by 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. For example:

  • During sports activities, a basketball or baseball may strike the tip of an outstretched finger.
  • Your finger might get caught in equipment such as a game jersey or pads.
  • You might fall onto your outstretched hand.

Symptoms of a Dislocated Finger

A dislocated finger is usually obvious. The finger appears crooked, swollen, and is very painful. It may be bent upward or at strange angles. You probably won’t be able to bend or straighten the finger if it is dislocated. Also:

  • Numbness or tingling with a severe location.
  • The injured finger may appear a pale color.
  • The dislocation may cause a break in the skin where the injury has occurred. If this occurs, you should get medical attention right away.

When to Seek Medical Care for a Dislocated Finger

When you have a dislocated finger, you should see a doctor at once. Delaying a visit to your doctor for a finger jam can make final treatment more difficult and can lead to delayed healing or permanent disability.

Seek medical attention immediately if there is any loss of sensation (numbness), if there are any open areas of skin, or if the finger is cold, pale, or bluish in color.

Exams and Tests for a Dislocated Finger

The doctor will first examine the finger you have injured. He or she will then x-ray the finger to confirm the dislocation and look for any broken bones.

Finger Dislocation Treatment

It is not recommended that you treat a finger dislocation at home. A visit to your doctor or the emergency department is usually necessary.

  • If you have a jammed finger, the finger will swell. To prevent further injury to the finger, immediately remove any jewelry, such as rings.
  • Apply an ice pack to your injured finger and elevate the hand above the level of your heart.
