Innovative Design and Manufacture of Hip Joint Prostheses Matching Human Bone Properties

Back to search results

Hip joint replacement surgeries are one of the most significant prosthesis operations worldwide. Titanium-based alloys and their composites have been a key class of materials in making the prostheses due to their good bio-compatibility as well as their high corrosion resistance, strength and toughness. To fulfil the demands of longer human life, the prosthesis materials must have properties closely matching the human bones'. However, there are significant property matching challenges between prostheses and human bones, causing stress-shielding, implant loosening and in turn premature failure. The aim of this research project is to develop a new process for the design and manufacture of hip joint prostheses which could closely match human bone properties but have a long in-vivo life. To carry out this research project, the student should have a good background in advanced manufacturing processes and property characterization of bio-materials.
