ABSTRACT:
A prosthetic socket 1 is made in a generally crescent shape with an outer cylindrical surface and includes horns 5, 6 which may be contracted, in order to allow it to be introduced, in the manner of a clip, in a cylindrical osseous cavity, where it is held by elasticity, without any cementing. The anchorage of this type of prosthesis is made directly onto the bone, using materials with a Young's modulus very close to the Young's modulus of the spongiosa tissue of the pelvis guarantees longevity of the anchorage, which is protected from loosening which may occur when cements of the methyl methacrylate type or others are used, such as metal or ceramic materials designed to be self-fixing, but of which the Young's modulus is sufficiently different from the Young's modulus of the bone that mechanical stresses may occur causing loosening. The invention also relates to an artificial head of a femur of three part construction.
