6、al 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 mecha

7、nism 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.

A. A pronated foot sustains either an external rotation or abduction force and creates the successive

9、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 late

11、 pathology. The first stage is lateral 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. 10醫(yī)療技術(shù)Figure 59-25 Supination-external rotation injury pathology.

12、he first stage is failure of the anterior 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 o

The second stage is syndesmosis (anterior inferior tibiofibular ligament and posterior inferior tibiofibular ligament) disruption. The third

14、stage is a bending fracture of the lateral malleolus with a transverse, laterally comminuted pattern.12醫(yī)療技術(shù)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.
