Abstract

Traumatism of the locomotor system of small unproductive animals is determined in more than 25-35% of cases of the total number of internal non-communicable diseases of animals. As for veterinary traumatology, the problems associated with fractures, deformities, bacterial contamination, and a decrease in osteoconductive and osteoinductive processes have not been fully resolved. Due to the possibility of using various methods of osteosynthesis using a variety of implants, it is advisable to use coatings on these implants in order to satisfy the specified parameters: coating thickness, morphological uniformity, roughness, presence and size of pores, adhesiveness, biointegration, resorption, as well as bactericidal and bacteriostatic effects. which in turn will speed up the consolidation process. This article highlights the results of studies concerning the X-ray pattern of experimental groups of small unproductive animals (dogs) using the developed osteoplastic biocomposite coating applied to the surface of implants (pins) for intramedullary and extrafocal osteosynthesis. The material for the research was X-rays of experimental animals (n=270). The purpose of the scientific study was to provide an X-ray assessment of the skeletal system in simulated fractures of the radius of animals (dogs) and intramedullary osteosynthesis with wires with the developed osteoplastic biocomposite coating. The team of authors, based on the dynamics of X-ray studies, found that the biocomposite coating developed by them provides high biocompatibility with subsequent biointegration into the tissue structures of the regenerate, which prevents the formation of fibrillar connective tissue and cartilage. Thanks to this biocomposite coating, an area of active osteoreparation is formed on all sides of the pin, thereby forming a bone case with osteogenesis conductor and inducer factors with antibacterial action, which regulates the direction of bone structure growth, while conducting long-term stimulation of angiogenesis and bone formation.
