Summary on Grant Application Form
The demand for total hip replacement is growing steadily with the ageing population. The current market is estimated to be 1.3 billion world-wide. Surgical intervention involves an extensive surgical exposure and use of prostheses that can be quite significant in size. Patient rehabilitation involves hospital stays of between 5 and 10 days, limited weight bearing and further rehabilitation for up to 3 months.A minimally invasive technique is proposed which uses a novel design of prosthesis together with image guidance technology (IGT). The implant will be inserted, with minimal disruption to the joint capsule, through the neck of the femur. Image guidance will make the procedure much less invasive, faster and easier to perform, and will improve the accuracy with which the prosthesis is implanted. Initially, the implant will be deployed by using endoscopic and navigation equipment, preserving as much bone as possible on both the femoral and acetabular sides. A key component of the programme will be research into how ultrasound sensing and its integration with endoscopy might be used intra-operatively. This should reduce the invasiveness of the procedure still further, reduce radiation dose to staff and patient, and reduce operating times. Novel augmented reality displays will be developed to allow the surgeon to relate the surgical plan directly to the surgical view.
