Apportioning deficits in bone size and density in women with fractures to growth or ageing by studies in their daughters [ 2001 - 2003 ]

Research Grant

Researchers: Prof Ego Seeman (Principal investigator)

Brief description Women fracture their bones because the bones are small and break easily and because the bones are thin or low in denseness (very porous like a honey comb). This study is aimed at identifying why women with fractures have small bones and why the bones are so porous. They may have these problems because they lost a lot of bone as they get older or because growth was abnormal so the size of the bone didn't reach its potential size or because the denseness of the bones didn't develop properly. The study will be carried out in women with spine or hip fractures and their daughters. All participants will have bone densitometry, provide a 24 hour urine sample and a fasting blood sample of 20 ml whole blood. Informed consent will be obtained from all participants. The bone density scan is associated with radiation exposure of about 4 mSv, about one tenth of a chest x ray, temporary bruising may follow taking blood. If we can understand the different ways osteoporosis can occur we can then start to devise specific treatments tailored to the individual. Also if we can identify the causes of small bones and bone thinness during growth it may be possible to correct some of these causes before the reduced growth and reduced building of bone occurs. We might also prevent the thinning of bone by identifying and removing causes of bone thinning.
