Abstract

Flexor digitorum profundus (FDP) tears in adolescents appear as avulsion tears in the FDP tendon, whereas longitudinal tears are very rare. Moreover, there has been only one reported case of intratendinous fibroma occurring in the flexor tendon of a finger. A longitudinal tear of the flexor profundus tendon associated with an intratendinous fibroma has not been previously reported. We report one case of a longitudinal partial tear accompanied by an intratendinous fibroma at the FDP tendon of the left middle finger after a hyperextension injury caused by the impact of a baseball. Given the rarity of longitudinal flexor tendon tears in adolescents, in such cases, the possibility of an underlying pathology should be considered.

Key Words: Finger, Flexor digitorum profundus, Intratendinous fibroma
