Fig. 2From: An anthropometric study of distal tibiofibular syndesmosis (DTS) in a Chinese populationLine A. Lines E and F are tangential to the anterior and posterior borders of the fibula, respectively. The shortest distance between lines E and F (a) is the length of the fibula. Lines D and G are tangential to the anterior and posterior colliculi of the tibia; the shortest distance between lines D and G (b) is the length of the tibia incisure. Finally, the length index is calculated as the length of the fibula (a) divided by the length of the tibia incisure (b), that is, a/bBack to article page
