A method for CT-based classification of posterior malleolar fractures. a Superimposed on an axial CT image of the ankle, a solid line is subtended between the medial and lateral malleoli. Then, a second (dashed) line is drawn perpendicularly to the first intermalleolar line, dividing the posterior malleolus area into medial and lateral segments. b–d CT images showing the different fracture types: postero-lateral (b), postero-medial (c), and postero-central (d)
