Abstract
(EN)
The disclosed bone implant (100) comprises a porous implant body (102) with an open porosity constituting throughout the porous implant body a three-dimensional network of porosity channels of dimensions suitable for bone ingrowth, and constitutes two substantially opposite ingrowth surfaces (104) to be positioned against the live bone tissue on implantation. In addition to the porosity channels, the porous implant body comprises a plurality of supply channels (105), wherein each one of the supply channels has a mouth in at least one of the ingrowth surfaces and extends into or preferably through the porous implant body substantially parallel to the force lines of the force field acting on the implant in the implanted state. Therein the supply channels have cross sections larger than the cross sections of the porosity channels, but small enough for being bridgeable by spontaneous bone growth without the help of bone growth enhancing material.
(FR)
L'implant osseux (100) divulgué par l'invention comprend un corps d'implant poreux (102) ayant une porosité ouverte constituant dans l'ensemble du corps d'implant poreux un réseau tridimensionnel de canaux de porosité de dimensions appropriées pour une pénétration osseuse par croissance et constitue deux surfaces de pénétration par croissance (104) sensiblement opposées à positionner contre le tissu osseux vivant lors de l'implantation. Outre les canaux de porosité, le corps d'implant poreux comprend une pluralité de canaux d'alimentation (105), chacun des canaux d'alimentation ayant une embouchure dans au moins l'une des surfaces de pénétration par croissance et s'étendant dans ou de préférence à travers le corps d'implant poreux sensiblement parallèlement aux lignes de force du champ de force agissant sur l'implant à l'état implanté. Les canaux d'alimentation ont des sections transversales plus grandes que les sections transversales des canaux de porosité, mais suffisamment petites pour pouvoir être reliées par croissance osseuse spontanée sans l'aide d'un matériau favorisant la croissance osseuse.
