Definitions

  • the invention relates to a surface replacement prosthesis for the natural femoral head with an outer spherical surface and an inner receiving space with an inner bone-facing lateral surface.
  • the current clinical state of the art provides for wear of the natural femoral head or hip joint head before a metal or ceramic surface replacement prosthesis.
  • Previous ceramic surface replacement prostheses are largely based on known metallic designs and are basically cemented.
  • the inner surface of the prosthesis is provided with cement pockets and a centering pin. Due to the exothermic reaction that occurs in the polymerization of the bone cement, there is a risk of thermally damaging the adjacent bone tissue. Furthermore, the bond between ceramic and bone cement is not long-term stable and it may come after a few years to loosen the prosthesis and consequent failure of the implant.
  • EP 0 542 815 B1 The state of the art is EP 0 542 815 B1, EP 1 268 364 A1 and DE 10 2013 202 243 A1.
  • An inventive cementless, all-ceramic surface replacement prosthesis with integrated porous osseointegrativer inner surface is an advantageous innovation.
  • Such a metal-free surface replacement prosthesis combines the advantages of the bone-saving operation with those of a biocompatible material, low wear of the sliding pair and excellent and long-term stable anchoring in the bone.
  • a surface replacement prosthesis according to the invention for the natural femoral head with an outer spherical surface and an inner receiving space with an inner circumferential surface is characterized by an integrated porous osseointegrative mating surface and by a all-ceramic design. The advantages of this surface replacement prosthesis are described above.
  • a method according to the invention for producing the integrated porous osseointegrative mating surface of the surface replacement prosthesis according to claim 1 is characterized in that the surface replacement prosthesis is produced from a sintered shaped body and a porous osseointegrative layer is applied to the lateral surface.
  • lateral surface is meant the bone-facing side, which abuts the bone after implantation.
  • the porous jacket surface is produced by applying a ceramic slip and spacers (pore former) in the green state and burning out the dummy during sintering.
  • the porous layer can be formed by foaming a ceramic slurry in the green state and subsequent sintering. About the sintering process, a connection is achieved. Burning out the placeholders during sintering creates an open - pored structure with a rugged surface, which advantageously supports bone ingrowth and ingrowth. See also EP 1 268 364 A1.
  • the porous shell surface can also be formed by joining a dense shaped body with a porous ceramic shaped body in the sintered state.
  • the porous shell surface can be formed by foaming ceramic slurry and sintering or infiltrating a porous support material with slip and sintering. The joining is preferably carried out by soldering or gluing.
  • porous osseointegrative lateral surface according to the invention can also be produced by 2K injection molding (dense phase and porous or pore-forming phase) and sintering. This type of coating in combination with a ceramic body is also metal-free.
  • the integrated porous osseointegrative lateral surface is formed by applying a porous metallic biocompatible layer on the already sintered ceramic base body (see EP 1 052 949 B1).
  • the porous bone-facing lateral surface may preferably be given additional functionality by further coating, such as a higher rate of integration or antibacterial effects.
  • Integration speed is the time of ingrowth with the bone. This can preferably be achieved with Biogläsern, Hydroxilapatit, functionalized proteins or hydrogels. This can preferably be achieved with Biogläsern, Hydroxilapatit, functionalized proteins or hydrogels.
  • the surface replacement prosthesis according to the invention consists entirely of a ceramic and can be implanted directly through the porous lateral surface.
  • the bone grows quickly into the porous surface, so that a tight fit is ensured soon after the operation.
  • no bone cement is used.

Abstract

Prothèse de resurfaçage pour la tête fémorale naturelle, qui comporte une surface externe sphérique et une cavité réceptrice interne pourvue d'une garniture interne orientée vers l'os. L'objet de la présente invention est la mise au point d'une prothèse de resurfaçage exempte de métal, combinant les avantages d'une opération épargnant l'os avec ceux d'un matériau biocompatible, et présentant une usure réduite des surfaces de glissement et un ancrage excellent et stable à long terme dans l'os. À cet effet, ladite prothèse de resurfaçage est caractérisée par la présence d'une garniture poreuse permettant l'ostéointégration, constituée d'un seul tenant avec ladite prothèse, et par le fait que ladite prothèse de resurfaçage est en céramique intégrale.
