Identification of Femoral Reference Lines and Angles in Sagittal Plane (Preliminary Report)

Solomin LN1,2 and Skomoroshko

Abstract

The Reference Lines and Angles (RLA) of femur in the sagittal plane which characterize its physiological sagittal bowing have not been found till now. Mutual relations of the mid-diaphyseal lines of the proximal, middle and distal thirds of femur in 30 femoral bones were studied. The angle between the mid-diaphyseal lines at the level of the proximal third is 10°, at the level of the middle third-16°, at the level of the distal third-7°. A comparatively small amount of the experimental bones makes it possible to consider our results as a preliminary data.
