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.

11、ology. 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. 整理课件Figure 59-25 Supination-external rotation injury pathology. The firs

12、t 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 or the d
