With the aim of defining the roentgenographic characteristics of a “normal” hip - meaning an articulation able to fully respond to static and dynamic stress without wear, we examined 60 hips of people over 70 years old from a population of Southern Italy. The parameters considered were: width of WBS, inclination of WBS, height of Gothic Arch, width of Gothic Arch, angle of aperture of Gothic Arch, a angle of Gothic Arch, diameter of femoral head, CE angle of Wiberg, neck-shaft angle, offset, angle of aperture of spherichal sector (SS), surface area of SS, volume of SS, radius of the spherical bowl, height of the spherical bowl, distance from the “tear drop” image of the fundus acetabuli. The main findings are: a) the WBS is horizontal; b) the gothic arch is orthogonal to the WBS; c) the spherical sector presents wide individual oscillations; d) the female hip has specific characteristics, being mainly smaller.
