A patient presents with foot pain after a fall from a ladder:

Foot fracture 1 Foot fracture 2

This foot X-ray shows a hindfoot dislocation at the talo-navicular and calcaneo-cuboid joints with varus angulation.  This pattern is suggestive of a Chopart’s fracture/dislocation.

What is a Chopart’s fracture/dislocation?  Glad you asked!  It is a dislocation at the specified joints above (talo-navicular and calcaneo-cuboid).  This hindfoot joint is commonly referred to as the Chopart joint.  Please see radiopaedia.org for further discussion and an even clearer X-ray for educational purposes:

Chopart’s Fracture/dislocation

It is important to understand that this is a HIGH energy mechanism.  With these high energy mechanisms it is also important to consider other injuries including proximal tibia, hip, and lumbar spine injuries.  This patient also had:

Tibial plateau fx 2 Tibial plateu fx 1

This is a quite comminuted fracture of the tibial plateau that may even make an orthopedic surgeon cringe.
