Застосування екстракортикального остеосинтезу за діафізарних переломів кісток кінцівок у собак

Abstract

The article presents an analysis of research results of domestic and foreign veterinary scientists concerning different treatments for dogs fractures of extremities. The researchers recommend to apply both conservative and radical treatment of orthopedic diseases, consisting in the use of different types of stable functional osteosynthesis (intramedullary, extra cortical and perosseous), creating conditions for early functioning of the injured area and the process of bone regeneration in the area of the fracture. It was established advantages and disadvantages of extra cortical osteogenesis and the feasibility of its application for diaphyseal fractures of extremities fractures in dogs. So, preference of closed intramedullary osteosynthesis consist in insignificant soft tissue injury. The downside is that that operation is performed blindly; is possible the injury of main nerves by pin, blood vessels, bones cracking. It is widely used open intramedullary drawback – destruction of bone marrow, vessels, circulatory disorders around the metal; reoperation is required to remove the metal holder. Extra cortical method provides reliable fixation of debris, especially for complex comminuted fracture. The disadvantage is the trauma during the imposition and removal of plates, infection of wounds. Perosseous allows to treat fractures of various localization, limb elongation, eliminate axial deformation and defects in bone and soft tissue of any origin and location, particularly complicated by osteomyelitis. But for its application requires special expensive equipment. Therefore becomes important the improvement of radical methods of treatment of fractures in order to stimulate regenerative processes and elimination of complications in the postoperative period.
