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.
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 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 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
Understanding the biomechanical effects of fixation strategies to improve the technology of fracture management. 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.

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

Transfemoral amputees fitted with an osseointegrated implant are experiencing numerous valuable benefits compare to their previous method conventional attachment. However, 40% of them present an early loosening of the implant or ruptures of the abutment.

Transfemoral amputees fitted with an osseointegrated implant are experiencing numerous valuable benefits compare to their previous method conventional attachment. 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

A Multi-Axis Biomaterials Testing Facility. 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 sm ....A Multi-Axis Biomaterials Testing Facility. 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
Attachment of Growth Factors to Pure, Plasma Modified and Coated Titanium Substrates. Titanium and its alloys are routinely used as medical and dental implants.

Despite coating with hydroxyapatite, a material well known to improve implant fixation, many such implants fail because of lack of strong integration with bone. This proposal aims at achieving long-term stability of titanium implants through their surface modification and subsequent attachment of growth factors. The use of latter has already been shown to help bone-implant integration. Successful project implementation will provide titanium implant surfaces that will help achieve speedier and improved implant fixation with long-term stability. Knowledge, expertise and techniques developed will help the industry partner expanding its research base and business and generating wealth in Australia. Training of world-class research students in the emerging field of biotechnology will be another major outcome.Read moreRead less

Summary
At total hip replacement, there has been a recent trend to use prostheses with a larger ball and liner in the socket. This may decrease the risk of post-operative dislocation, but may also increase the amount of wear, leading to bone loss and loosening of prostheses, which may then require replacement. This project will use a special type of x-ray to determine whether wear and movement of these new prostheses is clinically acceptable, so that they can be used with confidence in patients.
The Risks And Benefits Of Contemporary Total Hip Replacement

Funding Amount
$493,530.00
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.
