Abstract
(DE)
Die Erfindung betrifft ein Verfahren zur Herstellung eines offenporigen beschichteten Gelenkersatzimplantats, wobei wenigstens eine Schicht eines biokompatiblen Metalls oder einer Legierung davon auf eine Rohoberfläche des Implantats zur Erzeugung einer Implantatoberfläche aufgebracht wird. An der Implantatoberfläche wird anschließend eine Oberflächen-Mikrostruktur erzeugt. Dies geschieht mittels Ätzen der Implantatoberfläche, beispielsweise mittels eines Säurebades oder mittels Plasmaätzen oder durch das Aufbringen von feinen biokompatiblen Partikeln an der Implantatoberfläche. Die Schichtdicke der offenporigen Oberflächenschicht liegt im Bereich von 0,5 mm bis 1,5 mm und weist eine Porosität von mindestens 40 % auf.
(EN)
The invention relates to a method for the production of a joint replacement implant with an open-pored coating, whereby at least one layer of a biocompatible metal or an alloy thereof is applied to a raw surface of the implant to create an implant surface. A surface microstructure is then generated on the implant surface. The above is achieved by means of etching the implant surface, for example by means of an acid bath or by means of plasma etching or by the application of fine biocompatible particles to the implant surface. The layer thickness of the open-pored surface layer is in the range from 0.5 mm to 1.5 mm and has a porosity of at least 40 %.
(FR)
La présente invention concerne un procédé pour réaliser un implant d'articulation artificielle doté d'un revêtement métallique à pores ouverts, au moins une couche d'un métal biocompatible ou d'un alliage de celui-ci étant appliquée sur la surface brute de l'implant pour donner une surface d'implant. Contre la surface d'implant est ensuite produite une microstructure de surface, par gravure de la surface d'implant, par exemple au moyen d'un bain d'acide, par gravure au plasma ou par application de fines particules biocompatibles sur la surface d'implant. L'épaisseur de la couche de surface à pores ouverts vaut de 0,5 mm à 1,5 mm et ladite couche a une porosité d'au moins 40 %.
