The authors constructed a push-traction DDEF device to provide reduction stability while allowing early motion of the ring finger PIP for our patient's P2 pilon fracture. We created a novel DDEF device allowing PIP motion while immobilizing the DIP for the patient's concomitant P2 head/shaft comminuted fractures and mallet injury.
