Abstract:

The research had as its objectives fabrication and characterization of a porous alumina ceramic possessing a pore structure capable of accepting bone tissue ingrowth implantation of a load bearing porous alumina material to test bone ingrowth as a means of load bearing skeletal attachment determination of interfacial shear strength between bone and porous structures of an alumina ceramic, cobalt chromium alloy and high density polyethylene. A modified foaming procedure was developed to produce a porous bioceramic material. Load bearing attachment of a porous alumina ceramic implant by bone ingrowth was demonstrated. Interfacial shear strengths were found to increase with increasing implant time having an average of 1205 psi for porous Co-Cr alloy after 8 weeks, an average of 882 psi for porous alumina ceramic after 8 weeks and an average of 135 psi for porous polyethylene after eight weeks.
