NB: EU applicants are welcome and eligible and are guaranteed UK fee status throughout the PhD!! (Regardless of the Brexit outcome)

In orthopaedic surgery, we repair, reconstruct or replace parts of human joints. This requires fixing different types of implants to the bone. Conventional manufacture of orthopaedic implants has been from solid Titanium or CoCrMo alloys or ceramics, which are many times stiffer than the bone. Exciting new work in our research group proves we can make additively manufactured (AM) lattice structures that have the same mechanical properties as bone. This means we can now control the strain bone experiences in and around the implant. Bone is a dynamic material that responds to strain, getting stronger and denser if the strain increases. Thus, by controlling strain, we can now use the presence of an implant to increase the bone strength. This could be a major breakthrough in orthopaedic implant design. In this PhD we will demonstrate control of bone strains in a cadaver model of joint preserving and partial joint replacement surgery. We will also investigate methods to maximise the fatigue life of the implant structure when used in these configurations. The project will have AM at its heart, and involve hands on manufacture in Titanium alloy using our Renishaw AM250 system and extensive laboratory testing. Industry partners are Renishaw Plc and Embody Orthopaedic Ltd.

You will be an enthusiastic and self-motivated person who meets the academic requirements for enrolment for the PhD degree at Imperial College London. You will have a 1st class or 2.1 honours degree in mechanical engineering or a related subject, and a desire to work in a multidisciplinary team of engineers (both academic and industrial), and orthopaedic surgeons. A passion for engineering, demonstrated by extra-curricular activities or industrial experience is also desirable. Good team-working, observational and communication skills are essential.
