Fig. 1From: Morphological analysis of posterior malleolar fractures with intra-articular impacted fragment in computed tomography scansExample axial CT cross-sectional measurements. A Measured as the length of involved fibular notch (LIFN, length of involved fibular notch) and the stable fibular notch (LSFN, length of stable fibular notch). B Measured as the length and area of IAIF (LIAIF, length of IAIF, black; AIAIF, area of IAIF, white). C Measured as the area of posterior malleolar fragment (APMF, area of posterior malleolar fragment). D Measured as the area of stable tibial plafond (ASTP, area of stable tibial plafond)Back to article page
