Background. Structural and strength modifications occurred in cortical and cancellous femoral bone of ovariectomized rats were investigated by comparing dual X-ray absorptiometry and quantitative ultrasound with biomechanics and histomorphometry. Methods. These measurements were performed in 30 femurs, dissected from normal (baseline), ovariectomized (OVX) and sham-operated (sham) Sprague Dawley rats aged 14 months. Results. Femoral densitometric data showed a decrease in the whole femur BMDtot (-9%, ptot (-12%, pcondyle (-11%, pcondyle results: different structural and mechanical properties seem to justify the possible different sensitivity of the two methods.
