Morpho-functional characteristic features of the periosteum of the tibial regenerate bone at different stages of leg lengthening

Study of the dynamics of morpho-functional characteristic features of the periosteum of the tibial regenerate bone, being formed during leg lengthening under transosseous distraction osteosynthesis, has shown, that when tibial integrity is disturbed by the method of closed flexion osteoclasia, the preserved periosteum functions as a barrier and prevents growing of paraosseous soft tissues into diastasis zone. The cells of its cambial layer manifest their osteogenic properties, formig rough-fibrillar bone trabeculae in 5 postoperative days. It has been established, that during limb lengthening the periosteum, like the regenerate bone, acquires zonal structure and takes part in blood supply and reparative osteogenesis.
