Mallet Finger

Mallet Finger Overview

Mallet finger occurs when the outermost joint of the finger is injured. Mallet finger is a common athletic injury. Basketball and baseball players routinely experience jammed fingers, but the injury can occur because of a crushing accident on the job or even because of a cut finger while working in the kitchen. Any rapid motion that jams the tip of a finger against an object can cause a mallet finger.

With mallet finger, the tendon on the back of the finger (not the palm side) is separated from the muscles it connects, and this most commonly occurs at the index or middle fingers.
