Summary
Hip protectors are plastic shields or foam pads worn over the hip in specially adapted underwear. A number of studies in older people have shown that hip protectors are very effective if worn when a fall occurs and these have been available for the last few years in Australia. Unfortunately it has been difficult for older people to wear the hip protectors reliably and because of limited compliance with their use they have not been fully effective.

A number of studies in older people have shown that hip protectors are very effective if worn when a fall occurs and these have been available for the last few years in Australia. Unfortunately it has been difficult for older people to wear the hip protectors reliably and because of limited compliance with their use they have not been fully effective. This study will compare provision of a brochure, with supply of the older person's choice of hip protectors , with or without cost, and with or without contact with a nurse who will assist with use of the hip protector. After six months the level of use of the hip protectors will be checked. The new strategies tested in this study may increase compliance with hip protectors to a level where they will be effective if used at home in the community, in residential aged care facilities, and in hospitals.Read moreRead less
Effects Of Vitamin D And Calcium On Bone Strength, Balance And Falls In Elderly Women

Summary
Many osteoporotic fractures occur as a result of bone fragility and falls. Both falls and fractures are huge public health problems in Australia. Falls are the leading cause of injury-related hospitalization and death in person older than 65 years of age. During 1996 almost 36,000 people attended a hospital after a fall and 5% of these resulted in fracturing a bone. The incidence of fall-related hospital admission increases exponentially with age, reaching 4% per annum for men and 7% per annum f ....Many osteoporotic fractures occur as a result of bone fragility and falls. Both falls and fractures are huge public health problems in Australia. Falls are the leading cause of injury-related hospitalization and death in person older than 65 years of age. During 1996 almost 36,000 people attended a hospital after a fall and 5% of these resulted in fracturing a bone. The incidence of fall-related hospital admission increases exponentially with age, reaching 4% per annum for men and 7% per annum for women aged 85 years and older. In the community approximately one third of older people fall each year. Compared to men, women are three times more likely to be hospitalized or one and half times more likely to die from a fall-related injury. Importantly women have an increased risk of fracture and over 40% of women over the age of 50 will break a bone. Previous European and American studies suggest that calcium replacement may improve bone strength while vitamin D may reduce falls. However, the separation of these two effects has never been studied. We have previously studied elderly falling women who attended the Emergency Department of large teaching hospitals in Perth and have shown that many are calcium and vitamin D deficient. We are undertaking a short term randomized controlled trial of calcium alone or calcium with vitamin D, to study the effects on bone strength as measured non-invasively, balance and falls in this high risk group of subjects. We have already recruited 100 subjects and six subjects have completed their 6 months assessment. We plan to recruit the remaining 200 subjects during the following 12 months and give all subjects one year of treatment. At the end of this study we should be able to offer clear treatment guidelines for this high risk group of patients.Read moreRead less
Regulation Of Key Pathways Causing Peri-implant Bone Loss.

Summary
The failure of bone prostheses is becoming a major health problem in our aging population. Despite the impressive success of joint replacement surgery, a significant number of arthroplasties fail. It is now apparent that most implants fail due to bone loss around them which leads to loosening. This project aims to obtain a better understanding of the causes of implant failure and find ways to extend the life of these implants .
Does An Annual High Dose Vitamin D Supplement Decrease Healthcare Utilisation In Older Women?

Summary
The shorter bleaker days of winter can cause a vitamin D deficiency in Australian women, increasing their risk of osteoporosis and broken bones including hip fracture. New research suggests that the low winter levels of the vitamin may not be good for us in many ways and the NHMRC is funding a Geelong-based study to determine if Austrlia's elderly can improve their overall health by taking a once-a-year dose of vitamin D tablets.
Fractures, in particular femoral neck (FN) fractures, are a huge public health problem resulting in disabilities, mortality and financial cost to the community. The prevention of these fractures is based on estimation of bone strength. The decision whether someone needs treatment, or the effectiveness of a treatment can only be judged by estimating bone strength. The bottom line is that currently we cannot correctly estimate bone strength.

The prevention of these fractures is based on estimation of bone strength. The decision whether someone needs treatment, or the effectiveness of a treatment can only be judged by estimating bone strength. The bottom line is that currently we cannot correctly estimate bone strength. Present methods such as bone mineral density (BMD) perform poorly. Most people who fracture are not detected by BMD because their BMD is either normal or high, and many people with low BMD never fracture. The main aim of this grant application is to develop new tools to allow doctors and scientists worldwide to better estimate FN strength. To develop new methods to replace BMD, scientists need to make use of the 3D aspects of the bone such as size, shape and internal architecture. Presently, these 3D aspects (structure) have not been adequately studied and scientists incorrectly approximate them. As a result new methods are not any better. A good quantification of structure is needed. Another reason for the failure to accurately estimate the strength of bones is that estimates are based on a single parameter whereas the bone, like any architectural structure (e.g. building), comprises many components acting together to maintain its strength. To determine the strength based on density alone is incorrect; the size, the shape and things inside the structure need to be considered as a whole. After quantifying correctly the structure and components of bone strength, we will determine how they can be used individually and together to better estimate the strength of the FN in men and women. Tools generated will be used to better determine people likely to fracture and needing treatment; to better tailor and monitor treatments. A better understanding of the causes and epidemiology of fractures will ensue.Read moreRead less
