Jersey Finger Repair

Abstract

Jersey finger, also known as rugby finger, is an avulsion to the flexor digitorum profundus at its insertion on the base of the distal phalanx (zone I). It is frequently caused by forceful extension of the distal interphalangeal joint while actively flexing the flexor digitorum profundus. The tendon may tear from the distal phalanx independently or may avulse with a bony fragment. A classification system has been developed to categorize distinct injury patterns based upon the level to which the flexor digitorum profundus tendon retracted and the presence or absence of a bony avulsion fracture. Flexor digitorum profundus tendon rupture has been reported in all age groups but is most common in athletes. The injury frequently occurs during contact sports, notably American football and rugby, when grabbing the jersey of an opposing player as the player pulls or runs away. Surgical repair is the definitive treatment for all cases of complete rupture of the flexor digitorum profundus tendon. This video demonstrates a surgical approach using the suture anchor technique to repair a jersey finger injury.
