[Subtalar dislocations with medial or lateral displacement (author's transl)].

The authors have observed 20 cases of subtalar dislocation, 16 with medial displacement and 4 with lateral displacement. The treatment given and the results are described. An experimental study has also been made which confirms that in medial dislocations the talo-navicular joint dislocates first whilst in lateral dislocations the talo-navicular joint dislocates last. The severity of assoicated lesions is emphasised. It is concluded that in severe displacement with complete extrusion of the talus, tibio-calcaneal arthrodesis gave better results than excision of the talus.
