title: Absent Ring Finger Flexor Digitorum Profundus Presenting as a Jersey Finger.
abstract: We report the case of a patient who presented with an apparent acute avulsion of the ring finger flexor digitorum profundus (FDP), or jersey finger. At surgery, the FDP to the ring finger was found to be absent; also absent were the lumbrical to the ring finger and the A5 pulley. Absence of the FDP was confirmed with postoperative imaging. Although absent profundus tendons have been previously reported, none have involved the FDP to the ring finger. However, various reports have described abnormal connections between the ring and little finger flexor tendons.
