Zonal change of the optical density of regenerated bone and femur in lengthening of congenitally shortened femur using the technique of bifocal distraction osteosynthesis

The regularity, principles and dynamics of formation of the distraction regenerated bone of the femur being lengthened are studied in the work in patients with congenital femoral shortening on the basis of vast x-ray digital analysis. The material presented is illustrated by figures and graphs. The technique of study is given in details.
