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.
Highlights
In order to determine or exclude the presence of deformation of the long bone, reference lines and angles (RLU) are used
Anatomy of the femur in the sagittal plane is of great clinical importance
It is known that the diaphysis of the femur has a physiological bend in the sagittal plane [10-12]
Summary
In order to determine or exclude the presence of deformation of the long bone, reference lines and angles (RLU) are used. Anatomy of the femur in the sagittal plane is of great clinical importance. In the works devoted to the treatment of deformities of the femur, both for planning the correction of deformities in the sagittal plane and for evaluating the anatomical results of treatment, the authors use only the distal anatomical angle of the femur [6,13,14]. The use of only anatomical articular angles in the sagittal plane allows one to evaluate the physiological flexure of the femur not throughout the entire diaphysis, but only in the proximal and distal parts of the femur. The aim of the work was to determine the reference lines and angles of the femur in the sagittal plane, describing its physiological curvature
