This case shows the typical appearance of Tillaux fracture. It is a Salter-harris type III fracture commonly seen in adolescents where the medial aspect of the distal tibial physis is closed but the lateral aspect remains open.  CT study is helpful to assess the displacement of the tibial fracture fragment and articular surface congruity.

The absence of metaphyseal involvement helps to differentiate between Tillaux and triplane fractures.
