Classification

Closed pantalar dislocation could be subdivided to a pure dislocation and a fracture dislocation. Among 42 cases for whom associated fractures had been mentioned, 23 (54.7%) has pure closed pantalar dislocation without any fractures. Associated fracture was reported in 19 cases (45.3%)—9 ankle, 8 talus (mostly talar process), 2 metatarsal base, 1 calcaneus, 1 navicular, and 1 cuboid. Based on the direction of the dislocated talus, the most common direction of closed pantalar dislocation is anterolateral (37 cases, 84.1%), followed by posteromedial (3 patients, 6.8%). Only one case (2.3%) for each of anteromedial, posterolateral, medial, and lateral directions exist. It should be mentioned that the lateral pantalar dislocation case, reported by Ritsema,[2] did not have associated images, so it may have been anterolateral or posterolateral.
