Patent

CA 2439270

The present invention relates to the prevention and decrease of osteolysis produced by wear of the ultrahigh molecular weight polyethylene (UHMWPE). Methods are disclosed for the isolation of wear particles, preparation of implants exhibiting decreased wear in comparison to conventional UHMWPE and preparation of implants that cause decreased biological response in comparison to conventional UHMWPE. The implants created by these methods are also included in the present invention.

Cette invention se rapporte à la prévention et à la réduction de l'ostéolyse produite par usure du polyéthylène de poids moléculaire très élevé (UHMWPE). Cette invention décrit des procédés pour isoler des particules d'usure, pour préparer des implants possédant une usure réduite par rapport au polyéthylène UHMWPE traditionnel et pour préparer des implants qui produisent une réponse biologique réduite par rapport au polyéthylène UHMWPE traditionnel. Les implants créés par ces procédés sont également l'objet de cette invention.
