Chopart fracture-dislocation

Last revised by Dr Mostafa El-Feky on 24 Oct 2020

Chopart fracture-dislocations occur at the midtarsal (Chopart) joint in the foot, i.e. talonavicular and calcaneocuboid joints which separate the hindfoot from the midfoot. The commonly fractured bones are the calcaneus, cuboid and navicular.

The foot is usually dislocated medially and superiorly as it is plantarflexed and inverted, usually as a result of a high-energy impact, e.g. fall from height or road traffic collision. Where the foot is everted, lateral displacement occurs.

The Cyma line can also be disrupted 4

History and etymology

It is named after Francois Chopart, French surgeon (1743-1795) in Paris 1.
