A mallet finger, also known as hammer finger or PLF finger or Hannan finger, is an extensor tendon injury at the farthest away finger joint. This results in the inability to extend the finger tip without pushing it. There is generally pain and bruising at the back side of the farthest away finger joint.A mallet finger usually results from overbending of the finger tip. Typically this occurs when a ball hits an outstretched finger and jams it. This results in either a tear of the tendon or the tendon pulling off a bit of bone. The diagnosis is generally based on symptoms and supported by X-rays.During injury, this tendon is torn from its attachment site on the bone (called a tendinous mallet finger). But, there are also cases whereby the force of impact causes a small fracture at the base of bone where the tendon is attached to (called a bony mallet finger). In both cases, the tendon is no longer attached to the last bone of the digit and is thus unable to pull the end joint into a straightened position, resulting in a fingertip that droops.Treatment is generally with a splint that holds the fingertip straight continuously for 8 weeks. The middle joint is allowed to move. This should be begun within a week of the injury. If the finger is bent during these weeks, healing may take longer. If a large piece of bone has been torn off surgery may be recommended.
