Broken knuckle

Fact Checked

Knuckles are bony prominences that can be felt when clenching the fist. Knuckles are strong and do not break easily. A broken knuckle causes pain, swelling and stiffness and affects the daily activities of the individual. The hand is made up of finger bones and bones found in the palm. The bones of the fingers are called phalanges and bones in the palm are called metacarpal bones. The knuckles are found at the end part of the metacarpal bones and it is also known as the metacarpophalangeal joint. A broken knuckle is usually caused by punching on a hard object or a hard surface such as a wall. This injury is quite a common among boxers. It can be treated by immobilization, compression and splinting if there is a breakage.

Symptoms of a broken knuckle

  • There is pain and tenderness when the affected area is touched after an injury.
  • When clenching the fist, there is a shallow depression instead of a bony depression if a knuckle is broken.
  • Within a few minutes, the affected area will swell and there is difficulty in moving the knuckle joint that can spread to nearby knuckles and fingers. The swelling can be caused by buildup of blood and extracellular fluid.
  • There is bruising on the outer surface of the skin. The skin found over the knuckles becomes lacerated and blood oozes out of the wound.
  • The nerves that are near the knuckles might be damaged, thus causing numbness while the fingers are not capable of bending properly.

  • Apply an ice pack wrapped in a towel or use a towel that is immersed in cold water over the broken knuckle in order to minimize the swelling and pain.
  • Elevate the hand above the level of the heart in order to help drain blood from the affected area and minimize any bleeding from the open wounds.
