Patient-specific biomechanical modelling for improved treatment of spinal deformity. Spinal deformities negatively affect social acceptance, physical and mental wellbeing in children and adolescents. The direct costs of spinal deformity surgery are approximately $30 million per year in Australia, yet poor treatment outcomes due to post-operative complications incur a much higher cost as patients with persistent pain and disability face a lifetime of dependency and reduced ability to work.

Spinal deformities negatively affect social acceptance, physical and mental wellbeing in children and adolescents. The direct costs of spinal deformity surgery are approximately $30 million per year in Australia, yet poor treatment outcomes due to post-operative complications incur a much higher cost as patients with persistent pain and disability face a lifetime of dependency and reduced ability to work. The patient-specific biomechanical modelling techniques developed in this project will reduce complications and improve correction for Australian children who undergo spinal deformity surgery. Better treatment outcomes will ensure quality of life, health and productivity for spinal deformity patients throughout their entire lives.Read moreRead less
The virtual human knee. This project aims to investigate the Virtual Human Knee (VHK) which provides a baseline knowledge about knee mechanics in healthy individuals and a tool for studying knee mechanics in silico. The new knowledge can be used for identifying individuals most at risk for injury, developing solutions for preventing injury and for assessing knee reconstruction and implantation methods. As such, VHK will mitigate the burden of knee injury to Australia and worldwide by progressing ....The virtual human knee.

Inter-fragmentary movement in callus formation in the early phase of fracture healing. Computational models of the early phase of bone fracture healing can provide the means to characterise the biochemical factors that control this process, and subsequently influence successful healing outcomes, with or without surgical intervention. This unique approach, incorporating soft tissue and fixation device contributions to fracture healing, will ultimately provide a sound basis for clinical decision-m ....Inter-fragmentary movement in callus formation in the early phase of fracture healing. Computational models of the early phase of bone fracture healing can provide the means to characterise the biochemical factors that control this process, and subsequently influence successful healing outcomes, with or without surgical intervention. This unique approach, incorporating soft tissue and fixation device contributions to fracture healing, will ultimately provide a sound basis for clinical decision-making, implant design and future experimental studies. Facilitating treatment optimisation, the outcomes of this project will create opportunities to reduce healthcare costs, physical impairment, and productivity losses for the 150,000 Australian patients hospitalised annually with fractures.Read moreRead less
Formation of bone-like materials for bone repair and regeneration. A successful outcome for this project would lead to the production and application of new bone-like calcium phosphate materials. Enhanced bioactivity of this material would lead to higher but controlled rates of calcium phosphate release. An understanding of the formation process of these materials and the controlled release of calcium phosphates has the potential to slow the development of metabolic diseases such as osteoporosis ....Formation of bone-like materials for bone repair and regeneration.

Enhanced bioactivity of this material would lead to higher but controlled rates of calcium phosphate release. An understanding of the formation process of these materials and the controlled release of calcium phosphates has the potential to slow the development of metabolic diseases such as osteoporosis. The WHO reports that osteoporosis is the second largest health care problem world-wide. In 2002, 44 million people in the USA were estimated to be at risk. This and similar figures in Australia and around the world emphasize the urgency of understanding and appropriately combating weak bone degenerative diseases.Read moreRead less
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

The implications of resistance training for the control of movement. Resistance training (or weight lifting) is an essential element of comprehensive rehabilitation programs in a wide range of clinical settings. However, because we know little about how the organization of the nervous system is affected by training with high loads, the consequences of resistance training for our ability to control functional movements are unclear. The ultimate goal of this research is to generate basic knowledge ....The implications of resistance training for the control of movement. Resistance training (or weight lifting) is an essential element of comprehensive rehabilitation programs in a wide range of clinical settings. However, because we know little about how the organization of the nervous system is affected by training with high loads, the consequences of resistance training for our ability to control functional movements are unclear. The ultimate goal of this research is to generate basic knowledge about the impact of resistance training on nervous system function. The research will lead to the design of injury prevention and rehabilitation programs that are maximally effective, and provide a genuine benefit to the community.Read moreRead less
Calcium Signalling and Sequestration at Vertebrate Motor-Nerve Terminals. A fundamental process at Synapses is the release of transmitter from nerve terminals due to the initiation of calcium signalling in the temrinals by impulses. This calcium signalling must be terminated by sequestering processes. The aim of this project is to identify these processes in a vertebrate motor-nerve terminal and to determine the means by which calcium signals the changes in efficacy of transmitter release during ....Calcium Signalling and Sequestration at Vertebrate Motor-Nerve Terminals. A fundamental process at Synapses is the release of transmitter from nerve terminals due to the initiation of calcium signalling in the temrinals by impulses. This calcium signalling must be terminated by sequestering processes. The aim of this project is to identify these processes in a vertebrate motor-nerve terminal and to determine the means by which calcium signals the changes in efficacy of transmitter release during trains of impulses. This work will give a complete description of calcium signalling in a vertebrate nerve terminal and provide the basis for ameliorating failures in transmission from nerve to muscle.Read moreRead less
