Abstract
The analysis of the results of morphologic examination of vertebral body bone tissue obtained intraoperatively from 43 patients (20 - 67 years) with thoracic and lumbar spine injuries at different terms after trauma was performed. All patients were operated on via anterior approach to create ventral fusion. In the examined serial samples of vertebral body structures the quality and regeneration potential of bone tissue were assessed. It was shown that cell differentiation during the osteogenesis process was closely associated with angiogenesis. In the zones with active growth of microcirculatory bed vessels the normal cycle of osteoblast and osteocytes took place while hypoxia and acidosis resulted in pathologic osteogenesis. In patients under 50 years, both males and females) the full value consolidation time averaged 5 months. In patients over 50 years, independently of the gender, the decrease of spongy structures volume and bone mineral density was observed. The recommendations on surgical treatment tactics of patients with thoracic and lumbar vertebral body injuries were given.
