Mallet Finger

ExitCare ImageA mallet, or jammed, finger occurs when the end of a straightened finger or thumb receives a blow (often from a ball). This causes a disruption (tearing) of the extensor tendon (cord like structure which attaches muscle to bone) that straightens the end of your finger. The last joint in your finger will droop and you cannot extend it. Sometimes this is associated with a small fracture (break in bone) of the base of the end bone (phalange) in your finger. It usually takes 4 to 5 weeks to heal.


  • Apply ice to the sore finger for 15-20 minutes, 03-04 times per day for 2 days. Put the ice in a plastic bag and place a towel between the bag of ice and your skin.

  • If you have a finger splint, wear your splint as directed.

  • You may remove the splint to wash your finger or as directed.

  • If your splint is off, do not try to bend the tip of your finger.

  • Put your splint back on as soon as possible. If your finger is numb or tingling, the splint is probably too tight. You can loosen it so it is comfortable.

  • Move the part of your injured finger that is not covered by the splint several times a day.

  • Take medications as directed by your caregiver. Only take over-the-counter or prescription medicines for pain, discomfort, or fever as directed by your caregiver.
