Extra-articular triplane fracture of the distal tibial epiphysis.

We describe an extra-articular triplane fracture of the distal tibia in the skeletally immature patient. This variant of the triplane fracture has been largely ignored in the literature. The clinical significance of recognizing this fracture is that, although it constitutes an epiphyseal fracture, it remains extra-articular. Unlike the standard triplane fracture that exists through the tibiotalar joint, this variant can be treated acceptably with less than an anatomical reduction, therefore often avoiding the need for surgical management.
