Biomechanics of the human spine measured using magnetic resonance imaging. Statistics show that 80% of the population suffer back pain at some time. However, because the spine is very complex our understanding of its mechanics and the causes of back pain are still limited. This project will investigate the anatomy and activity of the spinal muscles and the behaviour of the intervertebral disc in living subjects using innovative Magnetic Resonance Imaging techniques. Significant outcomes will be ....Biomechanics of the human spine measured using magnetic resonance imaging. Statistics show that 80% of the population suffer back pain at some time. However, because the spine is very complex our understanding of its mechanics and the causes of back pain are still limited. This project will investigate the anatomy and activity of the spinal muscles and the behaviour of the intervertebral disc in living subjects using innovative Magnetic Resonance Imaging techniques. Significant outcomes will be new definitive descriptions of the detailed anatomy of the spine and its mechanisms. This will enhance the accuracy and detail of models under development for predicting spinal function following disease, injury or surgical procedures.Read moreRead less

Tissue engineering scaffolds offer an urgently needed synthetic biomaterials solution to overcome disease transmission from donor transplants. This work will combine biomaterial chemistry and designed surface topography to trigger bone formation within a scaffold for the first time in the world. Collaboration with national research leaders on stem cell and animal testing of the new scaffolds will provide the necessary interdisciplinary approach to generate a new product for patients in need of bone regeneration. Australia will benefit from the contribution to medical science, the development of a new device for rapid prototyping tissue engineering scaffolds, retain biomaterials research expertise, and generate new biomedical products.Read moreRead less
Improving orthopaedic/dental devices by surface chemical modification. The estimated world market for the orthopaedic implants is expected to be US$125 billion by 2010. Australia imports most of it's orthopaedic implants with an estimated cost in excess of AUD300 million by 2010. The current rate of prosthetic failures in orthopaedic patients is unacceptably high. The project aims to develop new implants that integrate better into bone, thus reducing the rate of revision arthroplasty. This would ....Improving orthopaedic/dental devices by surface chemical modification. The estimated world market for the orthopaedic implants is expected to be US$125 billion by 2010. Australia imports most of it's orthopaedic implants with an estimated cost in excess of AUD300 million by 2010. The current rate of prosthetic failures in orthopaedic patients is unacceptably high. The project aims to develop new implants that integrate better into bone, thus reducing the rate of revision arthroplasty. This would lead to a significant reduction in the cost of health care in our aging population and improve the quality of life for prosthetic recipients. Knowledge gained will facilitate the optimization of orthopaedic and implant dentistry, promoting the technology transfer from academia to the relevant medical device industry.Read moreRead less
Drug-delivery coating for a new generation of orthopaedic implants. In Australia, the number of people using artificial implants in orthopaedic and dental surgeries is rapidly increasing due to the higher average age of the population and higher expectations for an active and healthy life. The project will enhance the success rate of titanium implants by increasing the strength and stability of tissue at the interface between implant and host, particularly in case of hip joint implants, reducing ....Drug-delivery coating for a new generation of orthopaedic implants.

The project will enhance the success rate of titanium implants by increasing the strength and stability of tissue at the interface between implant and host, particularly in case of hip joint implants, reducing the need for revision surgery.

Interplay between mechanical and biological microenvironments in chondrocyte function: towards an understanding of cartilage pathology. This project will develop state-of-the-art laboratory models of healthy and diseased joints. These models will assist in answering questions about the causes of osteoarthritis, and provide information on how best to treat diseased joints.
Three-dimensional Simulation of Trabecular Bone Remodelling. Nearly 2 million Australians currently suffer from osteoporosis. Statistics indicate that 25% of Australian women and 17% of men will develop an osteoporotic fracture. The cost of osteoporosis is $7.4 billion per annum; the numbers of affected individuals and costs are expected to continue increasing. Clearly, improvements to osteoporosis diagnosis, fracture risk assessment, and effective treatments are still urgently needed. The p ....Three-dimensional Simulation of Trabecular Bone Remodelling. Nearly 2 million Australians currently suffer from osteoporosis. Statistics indicate that 25% of Australian women and 17% of men will develop an osteoporotic fracture. The cost of osteoporosis is $7.4 billion per annum; the numbers of affected individuals and costs are expected to continue increasing. Clearly, improvements to osteoporosis diagnosis, fracture risk assessment, and effective treatments are still urgently needed. The proposed project aims to create a tool for understanding the mechanisms of bone loss and predicting the effects of osteoporosis therapies. It represents a solid contribution to the knowledge base necessary for advancing osteoporosis research and ultimately reducing the incidence of osteoporotic fracture.Read moreRead less
Direct measurement of the kinetics of trans-femoral amputee gait during activities of daily living. This project involves the use of a novel technique to accurately measure the loads placed upon the lower limbs of above-knee amputees. Included in the subject group will be a number of amputees fitted with an artificial leg fitted directly into the bone. The ability to monitor a range of activities is possible by the use of a wireless telemetry system. The outcomes of this work will benefit ampute ....Direct measurement of the kinetics of trans-femoral amputee gait during activities of daily living.

This project addresses the National Research Priority of Promoting and Maintaining Good Health and specifically the Priority Goal of Ageing well, ageing productively. Osteoarthritis, the most common cartilage-related disease, affects nearly 1.4 million Australians, resulting in 2 in 1000 Australians undergoing total joint replacement, annually. The incidence and impact of cartilage damage on the Australian health and economy is expected to increase with the ageing population. This work leads to the development of a novel cartilage engineering technology platform that addresses Frontier Technologies and will thus provide the foundation for translation of this technology to the international marketplace.

Mobility of water in cartilage as a probe of molecular structure and function. Clinical diagnosis of early-stage osteoarthritis is difficult, and most patients are not diagnosed until a substantial degradation of cartilage has occurred as a result of the disease. This research will study the interaction between different components of articular cartilage and investigate, how this interaction can be exploited for the development of reliable and non-invasive techniques of cartilage imaging. Mobili ....Mobility of water in cartilage as a probe of molecular structure and function. Clinical diagnosis of early-stage osteoarthritis is difficult, and most patients are not diagnosed until a substantial degradation of cartilage has occurred as a result of the disease. This research will study the interaction between different components of articular cartilage and investigate, how this interaction can be exploited for the development of reliable and non-invasive techniques of cartilage imaging. Mobility of water molecules is a potent indicator of the microscopic structure of the cartilage scaffold. We will use this fundamental biophysical relationship to measure the internal architecture of collagen fibres; observe the changes effected by mechanical load; and distinguish between healthy and osteoarthritic cartilage.
