A mallet finger, also known as hammer finger, is an extensor tendon injury at the farthest away finger joint.[4] This results in the inability to extend the finger tip without pushing it.[3] There is generally pain and bruising at the back side of the farthest away finger joint.[3] Without proper treatment a permanent deformity of the finger may occur.[2]
It usually results from over bending of the finger tip.[3] Typically this occurs when a ball hits an outstretched finger and jams it.[3] This results in either a tear of the tendon or the tendon pulling off a bit of bone (Busch fracture).[3] The diagnosis is generally based on symptoms and supported by X-rays.[3]
Treatment is generally with a splint that holds the fingertip straight continuously for 8 weeks.[3] The middle joint is allowed to move.[3] This should be begun within a week of the injury.[3] If the finger is bent during these weeks, healing may take longer.[3] If a large piece of bone (>25%) has been torn off surgery may be recommended.[3][5] It is relatively common.[2]
