IN THIS ARTICLE
Mallet Finger Causes
Mallet finger occurs when the outermost joint of the finger is injured. With mallet finger, the tendon on the back of the finger (not the palm side) is separated from the muscles it connects. Three types of injuries commonly occur:
- The tendon is damaged, but no fractures (bone cracks
or breaks) are present.
-
The tendon ruptures with a small fracture caused by the force of the injury.
- The tendon ruptures with a large fracture.
