Differences in the mineral density of lower limb bone tissue in a healthy population sample.
This article presents the results of research to evaluate the impact of the functional asymmetry of the lower limbs on the precision of the densitometric measurements used in the diagnosis of metabolic bone diseases and in monitoring treatment outcomes. The study subject were 46 healthy adults, in whom the mineral density of the bone tissue (BMD) was measured in the proximal epiphysis of the femoral bone in both the left and right lower limb. In 43 of the analyzed cases (94%), higher BMD was found in the dominant extremity (avg. 2,8%, range 0,6-11,8%). Although lateralization of the lower limbs was confirmed in every case in this population sample, no statistically significant differences in BMD were found between the dominant and subdominant limb. However, due to the large differences in BMD found in individual cases, control DEXA measurements should always be taken from the same side when monitoring the outcome of metabolic bone disease treatment in individual patients.
