Summary
Ankle fractures are frequently seen in emergency departments, and isolated AO type B fibula fractures are the most common type of ankle fracture. Current treatment is equally divided between surgical, and non-surgical, as per surgeon preference. When managed surgically, these fractures consume considerable healthcare resources and expose patients to risks. This study will determine if surgery improves outcomes for patients with type B ankle fractures when compared with non-surgical management.

Summary
Fractures (breaks) near the wrist are the most common fractures treated. Treatment previously consisted of straightening and plaster casting in the emergency department, but standard treatment now includes admission to hospital and surgery to apply a plate and screws to the bone. The best evidence we have (which is limited) is that surgical plating does not provide important benefits over plastering. We aim to perform a multicentre trial comparing plating to plaster for these common fractures.
Outcome Of High Tibial Osteotomy For Medial Compartment Osteoarthritis Of The Knee: A Long-term Follow-up

Summary
In the young, active person, medial compartment osteoarthritis of the knee is a difficult problem to manage. Surgical options, such as total knee replacement, are often unsuccessful, due to functional restrictions and the need for revision surgery. An alternative is to extend the life of the arthritic knee by moving the primary weight-bearing surface to the other compartment (laterally), in an operation known as a high tibial osteotomy. This research looks at the outcome of this procedure.

Summary
Musculoskeletal diseases are the most common single cause of chronic disability in Australia and total joint replacement is rapidly becoming one of the most commonly performed operations. This burden of illness is likely to increase with our ageing population and there is an urgent need to obtain data relating to the costs and outcomes in the Australian context so that appropriate planning of health services and resources can be carried out.

This burden of illness is likely to increase with our ageing population and there is an urgent need to obtain data relating to the costs and outcomes in the Australian context so that appropriate planning of health services and resources can be carried out. The WHO (World Health Organisation) has declared 2000 to 2010 the Bone and Joint Decade, recommending that research into musculoskeletal disorders be a priority. We have been recruiting and following a unique cohort of osteoarthritis and rheumatoid arthritis patients, from both the public and private health sectors, who have been carefully documenting their health outcomes, health care costs (including primary, revision and bilateral hip and knee joint replacement surgery), out-of-pocket and indirect costs related to their arthritis. Long-term follow-up is now essential to obtain a clear picture of the impact of living with arthritis over time and the cost-effectiveness and predictors of good and bad outcomes of joint replacement surgery. The information derived from this study will be useful for patients and doctors in making their decisions about treatments, as well as for health care providers in planning of health services for arthritis sufferers. Given that the cohorts are already established, the study is in a unique position to provide ongoing important longer-term data for relatively low cost.Read moreRead less

Summary
Complications following total knee joint replacement continue to be a major cause for revision surgery and leads to a significant financial burden in terms of health care expenditure. Recent studies suggest that many of these complications are associated with post-surgical pain from the patella knee cap joint, commonly termed anterior knee pain (AKP). Post-surgery AKP may be influenced by the motion of the patella.

Recent studies suggest that many of these complications are associated with post-surgical pain from the patella knee cap joint, commonly termed anterior knee pain (AKP). Post-surgery AKP may be influenced by the motion of the patella. Recent prospective, randomised trials have compared clinical outcomes between people with TKA in which the patellar surface is replaced (patellar resurfacing) or retained, but have been unable to accurately account for differences in patellar movement in those people with post-surgery complications. To date, studies of patellar motion after total knee replacement have been limited to two-dimensional analyses. This study addresses the technological limitations of previous trials by utilising accurate techniques for directly measuring skeletal motion using kinematic radiostereometric analysis (RSA). These data will measure patellar kinematics in three-dimensions for the first time. This information will allow optimisation of the design of TKA and the surgical techniques required for their implantation. Furthermore, the results will assist in the identification of surgical indications for patellar resurfacing, and the kinematic factors associated with anterior knee pain following total knee replacement surgery.Read moreRead less
Development of a Prothrombogenic Bone Graft Substitute. The clinical demand for bone is massive and to counter this bone can be either harvested from the patient or bone substitutes are used.

The clinical demand for bone is massive and to counter this bone can be either harvested from the patient or bone substitutes are used. The success or failure of a bone substitute is determined the instant it come into contact with blood. The surfaces of traditional biomaterials induce a foreign body reaction. The aim of this project is to test the bone forming capacity of a biomaterial that is optimised to produce a natural response from the blood. This response will lead to the formation new viable tissue and eventually bone. Such a material will cause faster bone healing, less pain from graft sites, shorter hospital stays and shorter waiting lists. Read moreRead less

Severe limb trauma is the leading cause of disability to people of wage-earning age, and 150,000 Australians are hospitalised with fractures each year.

Severe limb trauma is the leading cause of disability to people of wage-earning age, and 150,000 Australians are hospitalised with fractures each year. Beyond the direct costs to the nation of $1000 million annually, temporary and permanent loss of limb functionality have a significant impact on productivity and quality of life. The computational models developed in this project will address critical gaps in the knowledge of fracture healing and the influence of different fixation devices. The project outcomes will provide a basis for tailoring fixation technologies for more reliable outcomes and minimised risk of non-union and complications, and thereby reducing physical impairment and the socio-economic burden of fractures.Read moreRead less

However, 40% of them present an early loosening of the implant or ruptures of the abutment. These problems are related to the load regime acting on the fixation system during post-operative rehabilitation and daily life activities. In this project, the direct measurement of the actual load applied on the abutment during:
· the load bearing exercises is essential to refine the post- operative rehabilitation program.
· every-day activities is crucial to improve the design and
testing of the implants and abutments.Read moreRead less

Damage to bones and joints, due to injury or diseases such as osteoporosis and arthritis, is a major cause of disability and cost to the nation. Australia's ageing population contributes not only to an increasing incidence of such conditions, but also to more patients out-living implants such as replacement joints. In 2001-2, Australia spent over $800 million on joint replacement. Because over 11% of procedures are revisions of failed implants, even small improvements in implant life represent significant cost savings. By accurately simulating conditions within the body, this biomechanical testing facility will lead to new developments in implant designs and materials, in turn improving quality of life, productivity and treatment costs.Read moreRead less
