Conditions

Ankle fractures

Interventions

Right and left ankle X-rays (mortise view) are taken in non-weight bearing and weight bearing conditions. Three observers measure the following three measurements (one of the observers measures twice
fibular variance, FV&quot
). D. A value obtained by dividing the value of C by the distance between the tibial plafond and the upper aspect of the talus (this is defined as &quot
fibular variance index, FVI&quot
). The following are evaluated
the normal value of FV and FVI, their inter- and intraobserver reliability, the difference between the right and left ankle, the difference between non-weight bearing and weight bearing conditions, an
