ligament) disruption. The third stage is a bending fracture of the lateral malleolus with a transverse, laterally comminuted
posterior malleolar failure.

FIGURE 53-7 Schematic diagram and case examples of Lauge-Hansen supination-external rotation and supination-adduction ankle fractures. A. A supinated foot sustains either an external rotation or adduction force and creates the successive stages of injury shown in the diagram. The supination-external rotation mechanism has four stages of injury, and the supination-adduction mechanism has two stages. Anteroposterior (B) and lateral (C) x-rays show an unstable supination-external rotation stage IV ankle fracture with the characteristic oblique distal fibula fracture and a medial side injury. D. An anteroposterior x-ray of a supination-adduction ankle fracture with a transverse fibula fracture and an impacted medial malleolar fracture.

Figure 59-28 Pronation-external rotation injury pathology. The first stage is medial failure of either malleolus or the deltoid ligament. The second stage is anterior inferior tibiofibular ligament disruption. The third stage is a spiral fracture of the fibula above the level of the plafond. The fourth stage is posterior inferior tibiofibular ligament failure, demonstrated as a
failure. The fourth stage is medial failure of either malleolus or the deltoid ligament.

FIGURE 53-8 Schematic diagram and case examples of Lauge-Hansen pronation-external rotation and pronationabduction ankle fractures. A. A pronated foot sustains either an external rotation or abduction force and creates the successive stages of injury shown in the diagram. The pronation-external rotation mechanism has four stages of injury, and the pronation-abduction mechanism has three stages. B. An anteroposterior x-ray of the ankle and tibia and fibula demonstrate a high fibula fracture. C. External rotation stress shows lateral displacement of the talus and widening of the distal syndesmosis. These x-rays are characteristic of a pronation-external rotation injury. D.
