Abstract

The present invention pertains to the field of medical techniques and can be used in traumatology and in orthopedics for placing hip-joint endoprostheses. The present invention relates to a cup for the cotyloid notch in a complete hip-joint endoprosthesis, wherein said cup comprises a thin-wall conical ring having a self-tapping thread on its outer surface as well as an opening in its upper base. The cup also includes a conical polymeric insert tightly fitted into the ring, wherein said insert has an open hemispherical recess formed at its lower base for mounting the prosthesis head, as well as an annular protrusion that engages with a corresponding groove formed on the inner surface of the ring. The cup further includes a porous disc which is fixedly mounted on the upper base of the insert. This invention is characterised in that the upper bases of the conical ring and the disc are spherical and in that they share a common centre. The outer surface of the porous disc, which engages the bone tissue, has a radius which is either 1.01 or 1.10 times larger than the radius of the sphere of the conical ring, the pores on said outer surface being open. The pores on the opposite surface and on the lateral surface are essentially closed. The groove on the inner surface of the conical ring is formed at the smallest distance possible from the lower base thereof. This invention provides a solid fixation, good stability and anatomic properties, reduced requirements concerning the mounting precision, a strong adhesion of the whole surface of the cup to the bone tissue as well as a good bone integration.

The disposal of a drive with a drive lower than the bottom of the cup removes it even more quickly from the hard cavity, therefore, it must be avoided. The same will reduce the effect of secondary fixation and the stability of the cup, t.κ. it is likely that it is “turning out” in the case of threading and significant loadings. The indicated version of the cup has and limited indications - the cup is not applicable in the case of significant defects of the bottom of the valvular cavity, t.κ. It does not cause the failure of such defects after the removal of the ring. All the noted drawbacks of the well-known part of the equipment are required (for partial compensation) due to the careful and special use of the appliance.
