6、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. Antero

7、posterior (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 im

8、pacted medial malleolar fracture.FIGURE 53-8 Schematic diagram and case examples of Lauge-Hansen pronation-external rotation and pronation-abduction ankle fractures. A. A pronated foot sustains either an external rotation or abduction force and creates the successive stages of injury shown in the di

9、agram. 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 an

The fibula is laterally comminuted.Figure 59-22 Supination-adduction injury pathology. The first stage is latera

11、l failure of either the malleolus or the collateral ligament. The second stage is a vertical fracture of the medial malleolus, which maybe associated with medial plafond impaction, as shown here. .Figure 59-25 Supination-external rotation injury pathology. The first stage is failure of the anterior

12、inferior tibiofibular ligament (AITFL). The second stage is a spiral lateral malleolar fracture at the level of the plafond. The third stage is posterior inferior tibiofibular ligament (PITFL) failure. The fourth stage is medial failure of either malleolus or the deltoid ligament.Figure 59-27 Pronat

13、ion-abduction injury pathology. The first stage is medial failure of either malleolus or the deltoid ligament. The second stage is syndesmosis (anterior inferior tibiofibular ligament and posterior inferior tibiofibular ligament) disruption. The third stage is a bending fracture of the lateral malleolus with a transverse, laterally comminuted pattern.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 fract
