Prevalence of PAD and osteoporosis (OP) both get higher with age. Clinical and epidemiologic evidence have showed an increased cardiovascular risk in OP and bone loss and fragility fractures in patient with cardiovascular disease.
This study will examine the relationship between vascular disease in legs and sBMD and vBMD at trabecular and cortical sites and bone microarchitecture.
The primary goal of our study is to determinate if presence of PAD is associated with lower sBMD and vBMD values at the tibias, assuming that BMD should be more alterate in the predominant vascular impairement site.
Our secondary objectives are to :

The following micro structural parameters assessed by HRpQCT at both tibias will be :
|
| Day 0 |
| Comparison between microstructural parameters at tibias | comparison between bone microarchitecture parameters at the tibia: the parameters will be compared between the most severely limb and the contralateral one. | Day 0 |
| Correlation between Lipid and bone parameters | We will study the relation between lipidic and bone parameters. Potential correlations between on the one hand (lipid parameters: total and HDL-cholesterol, triglyceridemia, LDL-cholesterol calculation) and on the other hand bone parameters: vBMD volumetric bone mineral density (mg HA/cm3) Ct.BMD: cortical volumetric bone mineral density (mg/cm3); Tb.BMD: trabecular volumetric bone mineral density (mg HA/cm3) | Day 0 |
| Percentage of densitometric osteoporotic patients | percentage of densitometric osteoporotic patients in the population | Day 0 |
| Evaluation of risk of fracture | The risk of fracture at 10 years will be evaluate by the Fracture Risk Assessment Tool (FRAX) survey. The FRAX® tool was developed by the then WHO Collaborating Centre for Metabolic Bone Diseases (1991-2010) at the University of Sheffield. It was launched in 2008 following approximately 10 years of meta-analyses of a variety of risk factors for osteoporotic fracture. Although not the only fracture prediction tool available, FRAX® is the only risk calculator which has been calibrated to rates of fracture and mortality per individual country and has been shown to identify a risk amenable to available treatments. | Day 0 |
| Evaluation of cardiovascular risk | Cardiovascular risk assessment using the SCORE tool (Systematic Coronary Risk Estimation). Four levels of risk are defined:
| Day 0 |
| Correlation between microstructural parameters at tibias and radius | comparison between bone microarchitecture at the tibia and of the radius. The following micro structural parameters assessed by HRpQCT at tibias and radius will be :
