A Generalization of Chevrot's Method for Determining Anteversion and Cervico-Diaphyseal Angles

Abstract
Chevrot''s method for determining the angle between the axis of the femoral shaft and the axis of the femoral neck (the cervico-diaphyseal angle), and the angle between the axis of the femoral neck and the diacondylar plane (the anteversion angle) in humans was investigated and generalized. Mathematical formulae giving the anteversion and cervico-diaphyseal angles in terms of 2 x-ray tube angles and 2 measured projections of the cervico-diaphyseal angle were derived. These formulae facilitate preparation of computer programs and tables for the routine clinical determination of the anteversion and cervico-diaphyseal angles in diagnosis, treatment and follow-up in hip pathologies.
