Description[edit | edit source]
Jersey finger (rugby finger) is an avulsion of the flexor digitorium profundus tendon (FDP) from its distal insertion on the distal phalanx (zone I). The ring finger is most commonly affected. Since the ring finger protrudes the farthest in the grasping position, it is more susceptible to FDP avulsion causing an inability to flex at the DIPJ.
Clinically Relevant Anatomy[edit | edit source]
FDP is one of the deep muscles of the anterior compartment of the forearm. It is the hybrid muscle supplied by two different nerves: medial half is supplied by ulnar nerve and lateral nerve is supplied by anterior interosseus nerve. It is the chief gripping muscle when the wrist is extended. It is the sole flexors of Distal Interphalangeal (DIP) Joint of digit 2nd to 5th.
