Case Discussion

In a mallet injury, when an object hits the tip of the finger or thumb, the force of the blow tears the extensor tendon. 

The injury may rupture the tendon or pull the tendon away from its attachment to the distal phalanx. In some cases, this is accompanied by an avulsion injury.

Most mallet finger injuries are treated with splinting. A splint holds the fingertip in extension until it heals.
