Dislocations of the subtalar joint are rare. Peritalar dislocation refers to dislocation at the talocalcaneal and talonavicular joints. Medial dislocation is the most common variety of this dislocation, resulting from severe inversion forces. Total talar dislocation refers to tibiotalar and subtalar joint dislocation.
