Abstract

A találmány szerinti biológiai integrációs tartományú ízületiimplantátumra, amelyet egy alaptest (1) és annak a csonttal érintkezőfelszínén kialakított pórusos felépítmény (5) alkot, az a jellemző,hogy az alaptesten (1) az integrációs tartományban különböző térbelialakú, irányú és méretű pillérhornyok (3, 4) vannak, és a pórusosfelépítmény (5) a bordák (2) külső és oldalfelületein és apillérhornyok (3, 4) alja mentén labirintszerűen van kialakítva, és apórusok kívülről nyitottak és egymással belső összeköttetésben lévőpórusok. Ebbe a felépítménybe nő be a csont, és alakulnak így kiegyrészt az implantátum felszíni stabilizáló részei, másrészt ahornyokban a peremszerű csontfal pillérek, implantálás után. A hornyokméretei, a labirintszerű felépítmény az implantátum környezetében lévőcsontszerkezethez, pórusméreteihez illeszkedő kialakítású.The joint implant with a biological integration region according to the invention, which is formed by a base body (1) and a porous superstructure (5) formed on its surface in contact with the bone, is characterized by the fact that the base body (1) has pillar grooves of different spatial shapes, directions and sizes in the integration region (3, 4) are present, and the porous structure (5) is formed in a labyrinth on the outer and side surfaces of the ribs (2) and along the bottom of the apillar grooves (3, 4), and the apores are open from the outside and pores connected internally. The bone grows into this superstructure, and thus the surface stabilizing parts of the implant are formed, on the one hand, and the edge-like bone wall pillars in grooves, on the other, after implantation. The dimensions of the grooves and the labyrinth-like superstructure are designed to match the bone structure and pore sizes around the implant.
