Hong, Sim, Ha, Kim, and Sung: Avulsion Rupture of Flexor Digitorum Profundus in Zone 1, Diagnosed in Early Stage

Abstract

Avulsion injury of the flexor digitorum profundus (FDP) tendon from the distal phalanx is considered as a rare injury. We report a patient who sustained a FDP tendon rupture insertion on her fifth finger as a result of a closed, hyperextension with no accompanying laceration or predisposing pathologic condition. Preoperative ultrasonography showed complete rupture of FDP and the gap between the tendon ends. According to the classification by Leddy and Pacter, this case is type II. The reconstruction of flexor tendon using pull-out suture and tie-over button. We are reporting a case with brief review of literatures.
