 * Stage 2: the talus displaces and fractures the fibula in an oblique or spiral fracture, starting at the joint.
 * Stage 3: tear of the posteroinferior tibiofibular ligament or fracture posterior malleolus
 * Stage 4: tear of the deltoid ligament or transverse fracture medial malleolus
 * Pronation-Abduction (Weber C)
 * Pronation-External rotation (Weber C)
 * Pronation-Dorsiflexion (Weber C)
