Mitchell PM, et al. - In this Retrospective cohort, researchers estimated the association of morphology of the posterior malleolar fracture with a spiral distal tibia fracture. They noted the highest incidence of posterior malleolus fractures (n=59, 48.4%) with intra-articular extension present in 68.9% of cases. They observed 93% of posterior malleolus fractures with cross-sectional imaging were Haraguchi type I (posterolateral-oblique type) with an average angle of 24 degrees off the bimalleolar axis. Whereas the remaining 3 were type II (transverse-medial extension type) fractures. They reported 61% visibility of posterior malleolus fractures of the time on preoperative radiographs.
