Summary
The treatment of large bone defects arising from trauma and tumour remains a challenge to orthopaedic surgeons. This project combines a well-established scaffold that can be custom-made to address patient specific requirements with a novel source of graft that can be harvested in significant volumes with minimal pain and morbidity. This novel tissue engineering approach will be evaluated in a previously established pre-clinical model that reflects the severity of challenging clinical scenarios.

Summary
There is a rapidly increasing and pressing medical need for the development of synthetic implants that can regenerate large amounts of lost or diseased bone. This project will produce a unique implant with optimal mechanical and biological performance, which represents a viable alternative to bone grafting with broad applications for the repair of large or challenging bone defects. Such an achievement will produce significant healthcare benefits and improved long-term outcomes.
HARNESSING THE PHYSIOLOGICAL EFFECTS OF STRONTIUM AND ZINC TO PRODUCE NOVEL BIOMATERIALS FOR ORTHOPAEDIC APPLICATIONS

Summary
Large skeletal defects resulting from congenital defects or disease processes are challenging to regenerate and represent a major financial burden to our health system. Bone graft treatments are widely used but have considerable drawbacks. Available synthetic alternatives lack the physical-biological properties necessary. We have developed new scaffolds with improved mechanical-biological properties for bone regeneration.
Functional Nano-cement Scaffolds For The Treatment Of Osteoporotic Bone Defects

Funding Amount
$408,768.00
Summary
Osteoporosis affects 1.2 million Australians and will cost $33.6 billion by 2022. This study aims to develop a novel nano-cement platform for custom-designed bone repair in osteoporosis, by using purpose-designed nanomaterials and advanced 3D printing technique. The research findings will lead to the development of a new bone repair strategy, expand knowledge on both biomaterials engineering and osteoporosis treatment, and improve the quality of life of Australians.
Innovative Antimicrobial Treatments For Successful Bone Allografts

Funding Amount
$473,706.00
Summary
Bone healing sites are commonly infected, and this is associated with adverse clinical and significant socioeconomic outcomes. These studies will determine whether our novel antimicrobials can be used to reduce bone infections by studying the combination of antimicrobials and bone in laboratory and bone fracture studies whilst minimising the potential of developing antibiotic resistance.
Novel Biocompatible Nickel-free Shape Memory Alloy Scaffolds For Biomedical Applications
Funder
National Health and Medical Research Council
Funding Amount
$530,789.00
Summary
The current project is aimed at the development of a new class of novel biocompatible nickel-free shape memory alloy (SMA) scaffolds for metallic implant applications. The new scaffolds possess the ability to exert a mechanical force on the surrounding bones, and stimulate new bone tissue ingrowth, due to their shape memory effect, superelasticity and bone-mimicking porous structure. The outcomes from this project will provide innovative implant materials.

Funding Amount
$318,768.00
Summary
Skeletal joint injuries often heal poorly with current treatment approaches and lead to the onset of osteoarthritis. This project will produce a synthetic graft with unique properties to mimic the complex structure of joint tissues, and high bioactivity to induce optimal healing of the joint. This graft will constitute a viable alternative for the treatment of skeletal joint defects, resulting in significant healthcare benefits and improved long-term outcomes.

Summary
In 1992, the orthopaedics industry fitted some 300,000 prosthetic devices, artificial hips, knees, giving this industry a global market of $2.1 billion with a projected market growth exceeding 10% per annum. In (1994-5) 5,717 prosthetic hips and 4,593 knees were surgically implanted in NSW of which 14% of hips and 9.5% of knees were revisions. Considerable health funding is allocated to joint replacement for the nation, although successful, outcomes are finite.

In (1994-5) 5,717 prosthetic hips and 4,593 knees were surgically implanted in NSW of which 14% of hips and 9.5% of knees were revisions. Considerable health funding is allocated to joint replacement for the nation, although successful, outcomes are finite. Importantly, and aside from costs, patients morbidity is high. The major cause of long-term failure of these prosthetic replacements is aseptic loosening, the result of bone loss at the bone-device interface. Novel approaches to development of more efficient implant materials would ultimately lead to major contributions to the mobility and and quality of life for these patients. Considerable effort has been devoted to alter surface characteristics of orthopaedic implants to improve the interlocking of device and skeleton. We were the first to demonstrate that surface chemical modification of biomaterials using selected ions resulted in an enhanced bone formation. This proposal is aimed at chemically modifying the surfaces of commonly used orthopaedic and dental materials, to improve the biocompatibility of new devices and the surface coatings for existing prostheses. Furthermore, this application will build on the in vitro data showing that particular peptides specifically bind osteoblasts and therefore have the potential to provide a surface on a prosthesis that is conducive to bone formation. To date, we have coupled these peptides to metallic surfaces and will proceed to study the osteoblastic phenotype and subsequent osteogenesis. Development of these novel biocompatible surfaces is anticipated to reduce patient morbidity and result in significant health care savings.Read moreRead less
