are mallet fractures displaced
Mallet finger is indicated in the middle finger in this photo. The tip of the finger bends downwards while the rest of the finger stays straight. [edit on Wikidata] Accepted after revision 7 July. 2009. We treated 32 displaced mallet finger fractures by a two extension block Kirschner-wire. technique. The clinical and radiological outcomes were evaluated at a mean follow-up of. 49 months (25 to 84). The mean joint surface involvement was 38.4% (33% to 50%) and. 18 patients (56%) had accompanying joint subluxation. Mallet Finger (Definition) Mallet finger is caused by a tear of the extensor tendon at the joint closer to the fingertip. It happens most commonly from a trauma which causes sudden flexion of the joint. The patient will notice that a 'droop' is present with the fingertip and is unable to extend at the joint. The tendon may tear where it joins on to the end bone of the finger, or it may pull off a small fragment of bone at this point (in which case it is called a mallet fracture). * Pain and swelling over the end of the finger. * The end of the finger lies in a bent position. Mallet fractures may leave a small bump on the top of the end joint and slight loss of bending of the joint, but pain is rare and the finger generally functions well. Occasionally the tendon fails to repair itself. It can be treated by a further period of splintage. In medicine, mallet finger, also baseball finger, dropped finger, dolphin finger, Virgin Finger, Hannan Finger, PLF Finger and (more generally) extensor tendon injury, is an injury of the extensor digitorum tendon of the fingers at the distal interphalangeal joint (DIP). Mallet finger can be caused by a blunt force on the DIP. Patients who are diagnosed with mallet finger have an inability to extend their finger and experience pain and numbness. Depending on how severe the injury is, the patient can be prescribed medication in order to prevent infection. X-ray showing fracture at the insertion of the extensor tendon.

Finger fracture: Finger fractures usually will present with localized swelling. There will also be tenderness at the fracture site. If the fracture is displaced there may be gross deformity of the finger. Some fractures at the distal portion of the finger may be a small avulsion and the presentation is a mallet finger. The distal finger joint will be flexed and the person is unable to straighten it. ...Read more. At the end of this time the splint is worn for one to two weeks at night and whenever the finger might be at risk of injury. Severe mallet fractures sometimes require surgical treatment, especially if the fracture has allowed the end joint to drop out of alignment.
