My interests in the area of Engineering for Life Sciences include the mechanics of revision Total Hip Arthoplasty. Revision THA’s use bone graft around the mechanical prosthesis and the interaction between the implant and the granular bone graft around it is akin to a pile foundation in sandy soil. The principles of granular mechanics can be applied to investigate the mechanical stability and durability of the revision THA’s. I have investigated with collaborating Orthopaedic surgeons at Princess Margaret Rose Hospital in Edinburgh and the University Hospital at Southampton, the mechanical stability of the implant soon after the surgery so as facilitate quick mobilisation of the patients. A device named Vibone was developed to improve the impaction density of the bone graft by allowing for free drainage of the fluid during impaction (see http://www.medicalfutures.co.uk/images/1182701989_Vibone.jpg). This device won a Medical Futures Innovation award in 2007. I am also interested in the stress transfer through the bone graft and subsequent plastic deformations during patient mobilisation phase during which the prosthesis is subjected to cyclic stresses.
