The mineral density of lower limb bones in patients with achondroplasia in the process of lengthening by transosseous osteosynthesis method

The results of changing mineral density of lower limb bones in patients with achondroplasia at the age of 6-20 years during their treatment by transosseous osteosynthesis method have been obtained. The most marked demineralization has been revealed by the 80-th day of distraction. Through overall decrease of bone density significant differences have been observed in the upper and lower thirds of both femur and leg bones in comparison with preoperative period (p
