Chopart fracture is a fracture/dislocation of the mid-tarsal joint (Chopart joint) of 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 high energy impact, e.g. fall from height or road traffic collision.
Where the foot is everted, lateral displacement occurs.
History and etymology
It is named after Francois Chopart, French surgeon (1743-1795) in Paris 1.
