Treatment for mallet finger

If you have mallet finger, the finger needs to be kept straight to let the injury heal.

A doctor or nurse will put the finger in a splint, securing it with tape. You'll still be able to bend your finger at the middle joint.

You'll need to:

• keep the splinted finger dry – the skin inside the splint can be sore if it gets wet
• wear the splint for up to 8 weeks, only removing it to clean your finger and the splint
• If the injury does not heal, you may need to wear the splint again for another 8 weeks.

Rarely, you may need surgery.

Cleaning the finger and splint

Clean the finger and splint every day. It's easier to do this if someone can help you.

It's important to keep the fingertip straight when the splint is off.

• Rest your finger flat on a table.
• Cut the tape and slide the splint off your finger.
• Wash the finger and the splint with soap and water.
• Dry the finger and splint.
• Slide the splint back into place over your finger, keeping the finger straight.
• Put new tape on. The middle joint of your finger can move, but it's important the damaged joint cannot move.
