Summary
Degeneration of the intervertebral disc is a painful disabling condition with major socioeconomic consequences. Medical problems associated with disc degeneration and back-pain, of sufficient severity to warrant consultation with a physician, are experienced by 90% of the population some time during their lives. In man, back pain increases in incidence in the third and fourth decades of life, peaks in the fifties and declines thereafter.

Medical problems associated with disc degeneration and back-pain, of sufficient severity to warrant consultation with a physician, are experienced by 90% of the population some time during their lives. In man, back pain increases in incidence in the third and fourth decades of life, peaks in the fifties and declines thereafter. Changes in population demographics indicate this problem will increase in severity over the next few decades. American Bureau of Census data indicate that between 1990 to 2010 the number of people >45 years will increase from 82 to 124 million, the number of elderly in emerging countries will also increase between 200 to 400% in the next 30 years. In the United States, back-pain is the second most common reason that people visit a physician and medical conditions related to back-pain account for more hospitalisations than any other musculoskeletal disorder. Despite its high incidence, associated problems of incapacity and economic implications, costed at $100 million per annum in Australia in 1992, and US$100 billion globally in 1999-2000 (Dorland Data Networks, PA, USA) the causes of low back-pain are still poorly understood. Disc disease is responsible for 23-40% of all cases of low back-pain. The management of discogenic low back-pain is currently empirical, directed either toward life-style changes to minimise symptomatology or to surgical resection or spinal arthrodesis to restrict articulation. Based on our recent findings and those of colleagues over the last 16 years, it is our strong conviction that it should be possible with a better understanding of disease mechanisms and with the use of modern technologies to inhibit, reverse or ideally prevent disc degeneration. Without such basic research there will be no scientific foundation upon which prospective therapies may be based.Read moreRead less
Understanding The Association Between Low Back Pain And Risk Factors For Chronic Disease

Summary
Being overweight or obese and smoking are believed to be significant contributors to the development of long term back pain. However we know little about the relationship between low back pain and these risks for chronic disease. This research aims to understand these relationships by testing if weight and smoking programs reduce low back pain disability in overweight or smoking patients, and secondly if back pain also influences risk factors for chronic disease.
Fractures And Bisphosphonates: Reviving Osteoporosis Treatment Uptake By Identifying The Genetic, Material, And Microstructural Risk Factors Of Atypical Femur Fractures.

Summary
Atypical femoral fractures (AFF) are uncommon, but catastrophic, complications of antiresorptive osteoporosis treatments including bisphosphonates. We will identify patients at risk of AFF by determining changes in their bone structure and quality, and identifying genes that increase the risk of these fractures. In this way, cheap and effective antiresorptive treatments can be targeted to patients at the lowest risk of AFF and alternative treatments to those at highest risk.
The Effect Of Weight Loss On The Risk Of Knee Osteoarthritis And Potential Modification By Biomechanical Factors

Summary
Osteoarthritis (OA) has the largest impact of any chronic disease on burden of disease borne in later life. This has been acknowledged by its listing as the 7th health priority in Australia. Knee OA is the most common reason for a joint replacement, thus imposing a huge financial burden to the community. Treatments which slow-prevent OA progressioning are limited and so prevention must play a key role. Obesity is the most significant, potentially modifiable risk factor for knee OA.

This has been acknowledged by its listing as the 7th health priority in Australia. Knee OA is the most common reason for a joint replacement, thus imposing a huge financial burden to the community. Treatments which slow-prevent OA progressioning are limited and so prevention must play a key role. Obesity is the most significant, potentially modifiable risk factor for knee OA. The combination of the current epidemic of obesity in Western countries and the aging of the population is likely to have a synergistic effect on the prevalence and incidence of knee OA. Despite the consistent relationship between obesity and OA, little work has been done on the relationship between obesity and biomechanical factors such as knee angle and muscle mass and how these may interact with obesity and weight loss in modifying the risk of knee OA. It may be that weight loss programs could be more effective at reducing the risk of OA if they are combined with programs aimed at correcting muscle weakness and malalignment. This has the potential to promote a better quality of life as people age and to reduce the economic burden of knee OA in the community.Read moreRead less
Centre For Research Excellence In Total Joint Replacement OPtimising OUtcomes, Equity, Cost Effectiveness And Patient Selection (OPUS)

Funding Amount
$2,500,000.00
Summary
Joint replacement surgery is one of the most successful surgeries performed in Australia and globally. With an ageing population, demand for this procedure will increase dramatically, placing burden on a constrained health system. This Centre targets the journey of patients undergoing joint replacement surgery, seeking to optimise patient safety and outcomes, in addition to improving efficiencies and equitablity of this important surgical procedure.

Summary
Patient expectation is the strongest predictor of satisfaction following total knee replacement. Dissatisfaction with surgery is reported in approximately 1 in 5 patients undergoing knee replacement. Unrealistic patient expectations and uninformed perceptions of potential benefits, risks and limitations of surgery lead to dissatisfaction in many cases.
