Bone tissue reparative regeneration for limb lengthening by the technique of combined distraction osteosynthesis

The characteristic features of bone tissue reparative regeneration in the process of limb lengthening were studied experimentally in 19 dogs during limb lengthening with the technique of combined distraction osteosynthesis using clinical, roentgenological and histological methods of study. Animals were withdrawn from the experiment after 28 days of distraction, 30 days of fixation, and 30 days after device removal. It was established that during limb lengthening with the combined technique a typical distraction regenerated bone was formed and the periosteum was the main source of its osteogenic potential.
