Factors influencing the course of regeneration of the body of the thoracic and lumbar spine. The purpose of the work is to develop a mathematical model of various methods of fixation and to study the distribution of internal stresses in structures when surgical treatment of damages of the thoracic and lumbar spine. Determine the influence of various factors, namely the role of hemorrhage, on regeneration of the vertebral body. Methods of research - clinical, biomechanical, mathematical, statistical. The most common traumatic and firearms damages of the chest and lumbar spine, which were subject to surgical intervention, were various clinical forms of explosive fractures of the spine. A mathematical biomechanical model of damages of the thoracic and lumbar spine was created. In the experiment it was proved that the use of the fixing structure allowed to reduce the stress in the destroyed vertebra. During the vertical load, the most intense is the back support complex. In the vertebrae, the legs of the vertebrae are more strained over the fixing structure, and below are the plates of arches. The maximum stresses in the fixing structure are located in the rods under the mechanism of fixing the upper screws. The use of a fixing structure with six fixing screws did not substantially change the VAT in the calculation model. The greatest reduction of stresses is observed in the rods of the fixing structure - about 20%. As a result of the morphological study, it was found that introduction into the perineal defect of the femur body of the fibrin bundle of rabbits contributes to accelerating bone formation in 14 days and 1 month. after injury, and bone tissue is formed directly on the fragments of the fibrin clot. 14 days after the operation under conditions of use of fibrin, the relative area of the bone tissue was 2.17 times greater than that of the control. In 1 month she filled the entire area of the defect, and in the defects of the bodies of the vertebrae of the rabbits of the control group, the areas of fibro-reticular tissue were preserved.
