Abstract

[Indexed for MEDLINE] 2. Jersey Finger. Abrego MO(1), Shamrock AG(2). In: StatPearls [Internet]. Treasure Island (FL): StatPearls Publishing; 2026 Jan–. 2023 Aug 7. Author information: (1)Hospital Italiano de Buenos Aires (2)University of Iowa Jersey finger (also known as rugby finger) is an avulsion of the flexor digitorium profundus tendon (FDP) from its distal insertion on the distal phalanx (zone I). The mechanism of injury is typically a forced extension of a flexed digit, such as trying to grab the jersey of an opponent during a high-speed sporting event. On exam, the affected digit remains in slight extension compared to the other digits. No active flexion of the distal interphalangeal joint (DIP) is possible. Treatment is surgical with the treatment plan dictated by the acuity of injury, the zone of injury, and any associated fracture. Copyright © 2026, StatPearls Publishing LLC.
