Development and characterization of an innovative material for artificial bone replacements

Metallic hip and knee implants are widely used but still have many problems. A major limitation of metallic implants is that their elastic modulus is not well matched with that of natural bone tissue, resulting in stress shielding. The stress shielding effects usually lead to reduced stimulation of new bone growth and remodeling which decreases metallic implant stability. In this study, an innovative approach is proposed which is to prepare gradual porous metallic structures to mimic natural bone tissues of various parts of human body. The figure indicates a comparison between the solid bone replacement, homogenous porous bone replacement, and the solid surface-porous core (SS-PC) with a graded porosity bone replacement.
