Abstract :
Bone fractures in dogs and cats are usually see and we concern with those in the clinic. Usually, fractures occur after a traumatic accident such as being hit by a car or falling from a height, some fractures occur following pathological bone weakening, which is seen with some neoplastic conditions such as osteosarcoma. The main goals of fracture stabilization; Immobilization of broken parts, quick repair of the damaged bone, return of primary mobility, full function and stability to weight bearing of the bruise limb. All internal and external fixation methods that allow significant intersegmental motion under weight bearing are considered flexible fixation. The best important point in the stabilization of fractures is that a possibility of repair, that is, the blood supply to the place is maintained and the fixation is not so tight that it leads to a delay in bone fusion. Open fixation and internal fixation have been used to restore bone anatomy and original mobility and to overcome the limitations encountered when treating fractures with skeletal traction or cast immobilization. The main goal of internal fixation is to achieve rapid and, if possible, full function of the affected limb with rapid rehabilitation of the patient. The selection of the internal fixation method is based on the classification of the fracture, break bone, synchronize injuries, open fracture, and of course the forces that are neutralized by the fixation method. Internal stabilization implants are made of stainless steel and include; There are intramedullary pins, orthopedic wire, plates and screws.
