Abstract
A biocompatible titanium alloy with low elastic modulus containing titanium, about 10-20 wt. % or 35 to about 50 wt. % niobium and up to 20 wt. % zirconium useful for fabricating of orthopedic implants. This invention relates generally to high strength, biocompatible alloys suitable for use as a material for a medical prosthetic implant and, in particular, a titanium alloy which has a relatively low modulus of elasticity (e.g. closer to that of bone than other typically-used metal alloys) and does not include any elements which have been shown or suggested as having short term or long term potential adverse effect from a standpoint or biocompatibility.
