Mallet finger occurs when you cannot straighten your finger. When you do try to straighten it, the tip of your finger remains bent toward your palm.

Mallet finger most often occurs when something hits the tip of your straightened finger and bends it down with force.
Wearing a splint on your finger to keep it straight is the most common treatment for mallet finger. You may need to wear a splint for different lengths of time.
If you wait to start treatment or DO NOT wear the splint as you are told, you may have to wear it longer. Surgery is rarely needed except for more severe fractures.
Your splint is made of hard plastic or aluminum. A trained professional should make your splint to make sure it fits correctly and your finger is in the right position for healing.
You will likely be able to return to your normal activities or sports, as long as you wear your splint all the time.
Be careful when you take off your splint to clean it.
When you shower, cover your finger and splint with a plastic bag. If they get wet, dry them after your shower. Keep your finger straight at all times.
Using an ice pack can help with pain. Apply the ice pack for 20 minutes, every hour you are awake for the first two days, then for 10 to 20 minutes, three times daily as needed to reduce pain and swelling.
For pain, you can use ibuprofen (Advil, Motrin), naproxen (Aleve, Naprosyn), or acetaminophen (Tylenol). You can buy these pain medicines at the store.
When it is time for your splint to come off, your health care provider will examine how well your finger has healed. Swelling in your finger when you are no longer wearing the splint may be a sign that the tendon has not healed yet. You may need another x-ray of your finger.
If your finger has not healed at the end of treatment, your provider may recommend another four weeks of wearing the splint.
