Summary
The failure of bone prostheses is becoming a major health problem in our aging population. Despite the impressive success of joint replacement surgery, a significant number of arthroplasties fail. It is now apparent that most implants fail due to bone loss around them which leads to loosening. This project aims to obtain a better understanding of the causes of implant failure and find ways to extend the life of these implants .

Summary
The failure of bone prostheses is becoming a major health problem. More than 26,000 hip, and an equal number of knee, replacements were performed in Australia in 2002 with the number increasing between 5%-10% each year for the previous 10 years. Disturbingly, the incidence of revision hip surgery in Australia is now more than 15%, meaning that, despite the impressive success of joint replacement surgery, a significant number of arthroplasties fail.

More than 26,000 hip, and an equal number of knee, replacements were performed in Australia in 2002 with the number increasing between 5%-10% each year for the previous 10 years. Disturbingly, the incidence of revision hip surgery in Australia is now more than 15%, meaning that, despite the impressive success of joint replacement surgery, a significant number of arthroplasties fail. It is becoming more common for young, active individuals to receive joint replacement surgery to improve their quality of life. This, combined with increasing life expectancy, and the known higher rate of failure of joint replacements in younger patients, means that the morbidity of a failed replacement, and the mobidity and associated mortality of revision surgery, will become an increasingly important health issue, with a major impact upon health budgets. The overwhelming majority of hip and knee prostheses have metal or ceramic on polyethylene bearing surfaces. It is now apparent that most implants fail due to bone loss around them leading to loosening, and evidence is accumulating that polyethylene wear particles are a major contributing factor to this process. It is therefore vital that we obtain better understanding of the causes of implant failure in order to extend the life of these implants and this project is designed to do so.Read moreRead less

Summary
The number of hip replacements undertaken in Australia is steadily increasing. The most common complications of hip replacements are dislocation and loosening due to bone loss around the implant, requiring complex and expensive revision surgery. This study will investigate the incidence of dislocation and, using a new diagnostic imaging technique, the incidence and amount of bone loss around a relatively new prosthetic material, the outcomes of which are not known despite its increasing use.
We will seek to address an important clinical problem in orthpaedics, namely the bone loss that commonly occurs around joint replacement prostheses. Termed peri-prosthetic osteolysis (PO), this bone loss can result in the loosening and ultimate failure and need for revision of the artificial joint components. PO is thought to be caused by the body's reaction to wear particles generated from the articulating surface of the prosthesis. However, it has not previously been possible to accurately exp ....We will seek to address an important clinical problem in orthpaedics, namely the bone loss that commonly occurs around joint replacement prostheses. Termed peri-prosthetic osteolysis (PO), this bone loss can result in the loosening and ultimate failure and need for revision of the artificial joint components. PO is thought to be caused by the body's reaction to wear particles generated from the articulating surface of the prosthesis. However, it has not previously been possible to accurately explore the relationship between prothesis wear and PO, or the progression of PO, because of a lack of techniques to image and measure the volume of PO around metal prosthesis components. We have developed a means to accurately and reproducibly measure the volume of bone loss, using CT, and will do so longitudinally in joint replacement patients to obtain the first information about the progression of PO. New computer based methods will be used concurrently to relate prosthesis wear and migration parameters to PO. Patients who come to surgery for replacement of failed prostheses will be investigated further by analysis of the tissues involved in the bone loss around prostheses. Basic science experiments will seek to understand the underlying causes of PO and the findings will be important in interpreting the clinical results. An animal model will be used to seek approaches to inhibiting the pathological response to wear particles. The significance of these studies is that they will lead to improved outcomes for joint replacement patients, increasing the interval to revision surgery, which is both extremely costly and brings an attendant morbidity and mortality.Read moreRead less
Numerical simulation of seismic waves in the regional and global earth with 3D Gaussian quadrature grids. The ability to realistically model the propagation of seismic waves through the global 3D earth, taking account of all internal and surface complexity, is extremely important for predicting the response to earthquakes and imaging the interior structure. This will lead to fundamental new knowledge on Earth constitution and heterogeneity, and will have spin-off benefits in others areas such as ....Numerical simulation of seismic waves in the regional and global earth with 3D Gaussian quadrature grids.

This will lead to fundamental new knowledge on Earth constitution and heterogeneity, and will have spin-off benefits in others areas such as exploring for oil and minerals, and better understanding of seismic hazard. The numerical modelling and seismic data analysis will be done on a supercomputer, thus providing important training for research students. Read moreRead less
