Case report of a rare mallet finger injury.
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.
