  2. Vertical medial malleolus fracture and impaction of anteromedial distal tibia
Supination-External rotation
  1. Anterior tibiofibular ligament sprain
  2. Lateral short oblique fibular fracture (anteroinferior to posterosuperior)
  3. Posterior tibiofibular ligament rupture or avulsion of posterior malleolus
  4. Medial malleolus transverse fracture or disruption of deltoid ligament
Pronation-Abduction
  1. Medial malleolus transverse fracture or disruption of deltoid ligament
  2. Anterior tibiofibular ligament sprain
  3. Transverse comminuted fracture of the fibula above the level of the syndesmosis
Pronation-External rotation
  1. Medial malleolus transverse fracture or disruption of deltoid ligament
  2. Anterior tibiofibular ligament disruption
  3. Lateral short oblique or spiral fracture of fibula (anterosuperior to posteroinferior) above the level of the joint
  4. Posterior tibiofibular ligament rupture or avulsion of posterior malleolus
