Radiological imaging of the formation of regenerated bone in distraction osteogenesis: an experimental study.
Introduction. One of the biological factors affecting the formation of regenerated bone in distraction osteogenesis is the method used for osteotomy. The purpose of the present study was to evaluate the course of bone regeneration using various types of osteotomy in an experimental setting.<br /> Material and method. Our research involved 35 Merynos sheep. Single-level tibia lengthening was performed in all these sheep in the proximal segment using an Ilizarov fixator. The material was divided into 5 groups depending on the osteotomy method used: closed corticotomy, open corticotomy, the Cattaneo method, osteotomy, and osteoclasia. The regenerating bone was evaluated by x-ray examinations performed in two standard projections.<br /> Results. The x-ray images were evaluated based on a descriptive analysis of the features of the course of bone regeneration in all the experimental groups. The regenerating bone the osteoclasia group was most abundant and homogeneous in structure.<br /> Conclusions. The formation of regenerated bone in distraction osteogenesis is dependent on the method of osteotomy. Radiological images of the course of regeneration in the various experimental groups showed differences in the intensity and rate of formation of new bone tissue. The formation and reconstruction of regenerated bone was faster in the osteoclasia group than in the other experimental groups.
