Mallet Finger Exercises

Home exercises for a fingertip that droops and will not straighten after an injury to the back of the finger.

Mallet finger deformity is when the end joint in any of the fingers is bent or “drooping” due to an injury to the back of the finger. The finger will not move as it should, and you will not be able to straighten the tip of your finger. It is important to do exercises to prevent permanent deformity in the finger.
