[3-dimensional model of the hip joint].
The main aim of this work was to build a three-dimensional theoretical pattern of the hip joint. It occurs as a generalization of the pattern of Pauwels, which was two dimensional. The equipment used is general mechanics plus an axiom we have added, which enables the calculation of the distribution of the surface pressures. Through theory, we find the experimental results of photo-elasticity. This pattern enables an analysis of the forces which act on the hip and their biomechanical role during gait. It leads to a better comprehension of the biomechanic failure, originating a pathology, and to a better choice in surgical correction. The calculation of the distribution of the surface pressures enables to understand the position of the acetabular rim. Our results contradict R. Bombelli's.
