Project Details

Osteoporosis is a major health problem affecting Australia’s ageing population due to the associated increased risk of fragility fracture. The currently utilised dual energy x-ray absorptiometry (DXA) has limitations in fracture prediction. Peripheral quantitative computed tomography (pQCT) is an alternative technique for determination of bone mineral measures that is applicable in a clinical setting, and is a suitable source for finite element analysis (FEA).

The objectives of this study are:

  • To describe the normal distribution of relevant pQCT variables including FEA-derived bone strength parameters and the determinants of these parameters in healthy young women; 
  • To obtain bone strength variables determined by pQCT-based FEA models in patients with LTF, and compare them to those of healthy controls;
  • To evaluate the potential clinical utility of pQCT-based FEA models for the assessment of bone fragility.

We are currently recruiting participants for three groups: healthy young females, older patients with low-trauma fracture and older healthy adults. We will request them to undergo both DXA and pQCT test and gather other data including demographics and fracture risks.
