title: Tibial torsion measured by computed tomography.
abstract: The clinical methods for measuring tibial torsion are based on the assumption that the proximal tibial tilt invariably is 0 degrees, an assumption which proved to be false in 38 legs examined using computed tomography. The conventional radiologic methods have not gained general acceptance. The various CT methods available for measurement of tibial torsion were investigated and have indicated too wide a variation to be clinically useful. At present, no reliable method for measuring tibial torsion seems to be available.
