The objectives of this research are to evaluate these anomalies quantitative and qualitative bone in the foot (calcaneus and ankle) through the use of MicroScanner. In parallel a whole body BMD and calcaneal ultrasound will be performed to measure bone mineral density as realized in clinical practice in a defined population of patients with type 1 or type 2. These bone abnormalities will be correlated with the presence of peripheral neuropathy and the rate of advanced glycation end products of proteins and reference to parameters of chronic inflammation and oxidative stress to better understand the pathophysiology and target a population at risk.
