Ultrasound transmission through the Os calcis in children: which side should we measure?

Ultrasound measurement of the os calcis is a promising technique when evaluating bone status. Large individual differences between the right and left calcaneus in adults were reported. In this study, calcaneal acoustic parameters in 373 healthy children and adolescents were investigated using a CUBAClinical bone densitometer. No significant difference was found between mean values on the right and left foot, however, individual difference in broadband ultrasound attenuation was 11 +/- 9.25%. Individual differences between both sides in ultrasound investigation of the os calcis should not be underscored either in adults or in children.
