With the increasing demand for superior performance placed on present day orthopaedic devices, there exists a constant demand to look for better materials for construction. Because of their good corrosion resistance, early devices were made from 304 or 316 stainless steels. However, the patient population has broadened to include younger individuals. These patients lead active lives and tend to stress the fracture fixation devices. Another requirement for younger patients is a longer implantable service: up to 20 years. With these requirements in mind, high-performance aerospace metal alloys based on cobalt chromium and titanium are used extensively. This paper discusses the requirements and the deficiencies of new materials; biocompatibility, biofunctionality, and manufacturing costs.
