How can doctors tell if my fingertip is broken?
How do doctors treat a broken fingertip?
Doctors will:
Wrap your fingertip to protect it—you'll usually wear this finger covering for about 2 weeks
For an avulsion fracture, the finger is placed in a splint that holds the finger in the correct place so the avulsion fracture can heal.
Drain blood that has collected under your fingernail by making a small hole in the nail with a needle
If the fracture is severe, do surgery to put the bones back in place
If your nail is badly damaged, take the nail off and fix the tissue underneath
If your nail is badly damaged, the tissue under the nail is usually damaged too. That tissue is where the nail grows from and needs to be fixed so that your nail won't grow crooked. Doctors inject numbing medicine in your finger and take off your nail. Then they can sew up any damage under the nail.
