title: Case report of a rare mallet finger injury.
abstract: Mallet finger injuries are commonly seen in the emergency room and the treatment is usually simple, consisting of extension splinting of the DIP joint. The hyperextension mallet finger is a rare variant. The diagnosis can be made if the fracture fragment involves more than 50% of the joint surface. For this injury splinting is inadequate and open reduction is the treatment of choice.
