Description of intervention(s) / exposure
We will recruit patients with osteoporotic fracture presenting to outpatients clinic. The patients will have peripheral quantitative computed tomography (pQCT) test besides the routine dual-energy x-ray absorptiometry (DXA) test during one one-hour site visit. This is a cross-sectional study and all the patients will only have one site visit. DXA is a routine test for patients with low-trauma fracture. Patients will still have DXA examinations even if they don't participate in this project.

Statistical methods / analysis
In the absence of preliminary data we have selected an opportunistic sample of 85 subjects. This sample size will be large enough to provide valuable information and is feasible based on clinic attendance rates.
Multivariable analysis will be used to determine the correlations between low-trauma fracture risk and these factors while adjusting for the differences between groups and potential confounders.
