Porous Metals as a Hard Tissue Substitute. Part II. Porous Metal Properties

Abstract

There is a need in anatomical restoration for a reliable, long-term method for attaching artificial materials to living tissue. The advantages and disadvantages of porous metals for attachment are discussed, and several porous metal types are compared. A unique porous metal called Void Metal Composite (VMC) is described. Preliminary data are reported on ingrowth and interface shear strength of VMC implanted 12 months in cat femora. Additionally, data are reported for interface strength in shear and cyclic loading for 6 week implants in goat femora.
