Morphological and radiological characteristics of bone regenerate under conditions of the use of carbon-carbon composite material

An important step in the surgical treatment of bone fractures, which can directly affect the rate and results of reparative regeneration, is the choice of fixation method, taking into account the biomechanical properties of both the bone and the fixation material. The aim of the study was to determine the morphological and radiological features of the regeneration of rat tibia fracture using a carbon-carbon composite material. The tibia of 12 white mature male laboratory rats of the Wistar line was studied. The animals were modeled with a simple incomplete fracture of the tibia of the posterior left limb. All rats were divided into 2 groups of six in each. The first group (control) - which did not undergo any fixation after modeling the fracture. The second group consisted of experimental animals that underwent intramedullary fixation with a carbon-carbon composite material after fracture modeling. Sections made according to standard histological methods were stained with hematoxylin and eosin for examination microscopy. X-ray examination was performed using an X-MIND Unity apparatus (Italy). The study found that in animals with modeled incomplete simple transverse diaphysis fracture of the tibia and intramedullary fixation with implants made of composite.
