Finger Injury

Definition

  • Injuries to fingers

Types of Finger Injuries

  • Cuts, Scrapes (skinned knuckles) and Bruises are the most common injuries.
  • Jammed Finger. The end of a straightened finger or thumb receives a blow. Most often, this is from a ball. The energy is absorbed by the joint surface and the injury occurs there. This is called traumatic arthritis. For jammed fingers, always check that the fingertip can be fully straightened.
  • Crushed or Smashed Fingertip. Most often, this is from a car door or a screen door. The end of the finger may get a few cuts or a blood blister. Sometimes, the nail can be damaged. Broken bones are not common with this kind of injury. If they do occur, they are at risk for a bone infection (osteomyelitis).
  • Fingernail Injury. If the nailbed is cut, it needs sutures to prevent a deformed fingernail.
  • Subungual Hematoma (Blood Clot under the Nail). Most often caused by a crush injury. This can be from a door crushing the finger. It can also be from a heavy object falling on the nailbed. Many are only mildly painful. Some are severely painful and throbbing. These need the pressure under the nail released. A doctor can put a small hole through the nail. This can relieve the pain and prevent loss of the fingernail.
  • Dislocations. The finger has been pushed out of its joint.
  • Fractures. Finger has a broken bone.

Pain Scale

  • Mild: your child feels pain and tells you about it. But, the pain does not keep your child from any normal activities. School, play and sleep are not changed.
  • Moderate: the pain keeps your child from doing some normal activities. It may wake him or her up from sleep.
  • Severe: the pain is very bad. It keeps your child from doing all normal activities.
