[Repair osteogenesis during limb elongation using transosseous distraction osteosynthesis].
The objective of this study was the investigation of morho-functional peculiarities of repair osteogenesis during the surgical extremity elongation using transosseous distraction osteosynthesis. In experiment performed in dogs it was found that the extremity elongation using Ilizarov apparatus the distraction changed the spatial organization of osseous regenerates which acquired the characteristic zonal structure. Spheroidal bony trabeculae were transformed in the distraction regenerates into cylindrical primary osteons, which were formed along vertically oriented vascular loops. The osteogenic cells demonstrate intracellular markers--mitochondrial crystalline mineral inclusions.
