Fig. 1From: Morphological characteristics of the posterior malleolar fragment according to ankle fracture patterns: a computed tomography-based studyThe radiographicmeasurements on the cross section. a The cross angle (α) wasdetermined by measuring theangle between the bimalleolaraxis and the major fracture line. b The fragment lengthratio (FLR) was determined by calculatingthe percent of length (l)/length (L). c The fragment arearatio (FAR) was determined bycalculating the percent of area(s)/area (s + S)Back to article page
