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.
Metacarpal fractures are generally described by the location of the fracture. Fractures in the center of the bone are called metacarpal shaft fractures. Fractures by the base of the finger at the knuckle are called metacarpal head fractures. Lastly, fractures at the wrist-end of the bone are called fractures of the base of the metacarpal.
