Morphological study of the human acetabulum: biometry

LUNA, M. P., DESNOYERS, V., CHARISSOUX, J. L. et al. 

Abstract: The anatomic study of the acetabulum is made to help the resolution of the mechanical loss problem of the cotyle in the total replacement of the hip. Heigh, ant post diameter, depth, the distance between the horns of the articulated half -moon and the distance between the real vertex of the acetabulum and the vertex of the issosceles triangle, which base is the distance between the two horns, were measured in 150 acetabulum. It has been proved that the acetabulum is not hemispheric, but ogival. There exists a predominance of heigh upon the ant post diameter of 5,86 mm, ring level average, that is related to charges transmission. It is shown that the distance between the real vertex of the acetabulum and the vertex of the issosceles triangle, which joins the two horns of the articulated half-moon, is 24,3 mm average. This constitutes the elasticity zone in the moment of the charges transmission
