METHOD FOR MODELING OPEN FRACTURE OF TALOCRURAL JOINT IN EXPERIMENTAL ANIMAL

摘要

The method for modeling the open fracture of the talocrural joint in the experimental animal comprises the dissection of the skin and the soft tissueslocated over the joint, the exposure of the bone and its resection, the reposition and the fixation of the bone fragments followed by the exposure of the postoperative wound to the low intensity laser radiation and the assessment of the results of the reparative regeneration of the bone tissue. With the aid of the hooks, the tendons of the long flexor of the toes and the extensor of the great toe are taken aside medially. The tendons of the long extensor of the toes, the superficial flexor of the toes, the anterior tibial muscle, and fibular muscles are taken aside laterally. The artrotomy is performed. The fracture of the internal ankle is modeled with the aid of the scalpel from inside the articular surface of the distal epimetaphysis of tibia, then the fracture is fixed. In addition, the results of the reparative regeneration of the bone tissue are assessed taking into account the morphological aspects of cell differentiation, microtopography, cytoarchitectonics of cell elements in the setting of the complex use of fixation, extension and surgical treatment as well as the laser irradiation. The computer data processing is performed.
