Abstract
|
|
|
|
Avulsion fracture of flexor digitorum profundus (FDP) tendon is relatively rare fracture at the distal phalangeal base than avulsion fracture of terminal extensor tendon. Terminal extensor avulsion fracture, known as bony mallet finger, could be successfully treated by closed reduction and pinning, such as extension block technique. However, most of FDP avulsion fracture, known as Jersey’s finger, needed open reduction, because of the proximal migration of fracture fragment and difficulty of pin fixation. Up to date, most of FDP avulsion fractures were treated by open reduction and fixation by pull-out suture or suture anchor technique. We report a case of comminuted FDP avulsion fracture, successfully treated by open reduction and mini-plate and screw fixation technique.
