Findings collectively in keeping with a Chopart injury.
Case Discussion
Chopart joint sprains are a type of midfoot injury and are often overlooked compared to Lisfranc joint injuries. Signs of a Chopart joint injury include bony avulsion dorsal calcaneonavicular ligament, bony avulsion fracture of the talar attachment of the talonavicular capsule, and anterior calcaneum process fractures 1.
