title: A new method for tibial torsion measurement by computerized tomography.
abstract: BACKGROUND
  Computerized tomography (CT) is the gold standard technique for tibial torsion assessment. This study compared two methods of tibial torsion assessment and proposed a new method, which could be of value in cases of abnormal fibular changes.
  
  
  METHODS
  The CT-scanograms of 60 participants were assessed by using two different techniques, differed in determination of the distal tibial axis.
  
  
  RESULTS
  The interobserver reliability was 0.861 and 0.863 in the first and second methods, respectively. The intraobserver reliability in both measurement methods was 0.868.
  
  
  CONCLUSIONS
  We proposed a reliable method, independent of the fibular midpoint, in assessment of tibial torsion by CT.
