What is mallet finger?

Mallet finger is a bent fingertip that won't straighten.

It happens after an injury tears the tendon on the top of your finger. Tendons are tissue that connect a muscle to a bone.

  • The torn tendon makes your fingertip droop

  • Mallet finger usually happens when you jam your finger, such as by catching a ball

  • A splint that holds your fingertip straight may let the tendon heal

  • Sometimes the tendon doesn't heal and your fingertip stays bent

Sometimes the injury also cracks the bottom of the bone in your fingertip.
