Introduction: The usual causes of flexor tendon injuries in hand are penetrating wounds. Closed injury and avulsion of flexor tendon are rare and mostly occur as avulsion of flexor digitorum profundus tendon of ring finger from its bony insertion at distal phalanx. Closed avulsion of flexor digitorum superficialis is even rarer. The rarest is closed and simultaneous avulsion of both flexors in the same finger and only about ten cases are reported in the literature. Case Report: Patient was a healthy 27-year-old right handed male shopkeeper. He fell down during his work ten days before referring to the hospital. After this event he was unable to flex his left fourth finger through interphalangeal joints. There was no injury to the skin of his hand. With the impression of closed rupture of both flexors of ring finger he underwent operation and repair of the flexor profundus tendon. Conclusion: Closed injury of both flexor tendons should be considered in differential diagnosis in similar situations even though they are rare.
