The 1950’s saw the first use of titanium in orthopedic applications and now titanium is the standard material of choice for orthopedic devices such as hip joints, bone screws, knee joints, spinal fusion cages, shoulder and elbow joints, and bone plates.
Titanium has been selected as a metal of choice in the orthopedic segment of the market because it is inert in the human body, it is resistant to attack body fluids, has proven to be compatible with bone density, is strong and has a low modulus, hence making it an excellent material of choice in the orthopedic arena.
The human body readily accepts titanium as it has proven to be more biocompatible than stainless steel or cobalt chrome. In addition, titanium has a higher fatigue strength than many other metals. Compatibility with MRI (Magnetic Resonance Imaging) and CT (Computed Technology) also contribute to the selection of titanium as the material of choice in orthopedic applications.
