Uso de fixador externo em fratura de tíbia em canino: relato de caso

Abstract

Fractures in long bones are common, with the tibia being one of the most affected and occur when the bone is subjected to a stressful situation, causing rupture of the bone cortex. It is mainly the result of trauma caused by falls or being run over. External skeletal fixation is a method of repairing fractures, being minimally invasive, reducing the risk of bone devitalization, contamination and, consequently, infection. This work aimed to report the case of a comminuted diaphyseal fracture in the tibia of a canine animal, male, 3 years and 11 months old, weighing 10.8kg, who suffered a fall at home and was treated at the hospital. Veterinarian Niterói, in Rio de Janeiro. Surgical resolution was achieved through osteosynthesis using an external Kirschner wire fixator and polymethyl methacrylate resin. Postoperative follow-up was carried out, with bone consolidation of the fractures 50 days after the surgical procedure. The external fixation described in the present study proved to be efficient and safe as a method of treating tibial shaft fractures, preserving the local biological status and providing passive and active movement in the immediate postoperative period.
