Quantitative bone computed tomography and bone densitometry have shown to be useful parameters of evaluation of mineral bone loss. Recent studies have demonstrated that ultrasonometric measures are also suitable on evaluation of bone microstructure and fracture risk, linked to bone "resistence". The aim of this study was compare ultrasonometric with densitometric bone values in a sample of female patients, per and post menopause. Authors evaluated 500 white women patients, per and post menopause, in a sample of Campinas population. All of them underwent calcaneus ultrasonometric evaluation (Achilles Lunar Equipment) and bone densitometry (DEXA – Dual Energy X-ray Absorptiometry – IQ Lunar Equipment) of lombar vertebras and femur, in a single day. Afterward, it was proceeded data statistical analyses. It was noted statistically significant correlation between ultrasonometry and column bone densitometry (r=0,49) and femur (r=0,61). Negative correlation was found relative to ultrasonometry and age (r=-0,49). Ultrasonometry can, even without substitute bone densitometry measure, evaluate the "stiffness" of bone microstructure, because of the positive correlation between densitometric (femur mainly) and ultrasonometric values noted in this casuistic.
