A new method for tibial torsion measurement by computerized tomography

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. (C) 2015 Prof. PK Surendran Memorial Education Foundation.
