Answer

Jersey finger

  • Avulsion of the flexor digitorum profundus from its insertion on the volar base of the distal phalanx results in the jersey finger. The mechanism of injury most commonly occurs in football when a player grabs the opponent's jersey. There is forced hyperextension of the DIP joint against an actively contracting flexor tendon. The ring finger is most commonly involved. Pain and swelling of the affected finger occurs, with loss of active flexion of the DIP joint.

  • This injury is often overlooked because on physical examination there is no obvious deformity present and the loss of DIP flexion is either not appreciated or dismissed secondary to pain or soft-tissue swelling. If one suspects flexor tendon avulsion, then gentle active flexion of the DIP joint should be tested specifically. Radiographic findings are often normal but may reveal a small avulsion fracture.
