Background: Trauma is the main cause of spinal fractures and dislocations in humans and large animals. Clinical signspresent with acute onset and vary according to the location and severity of the spinal cord injury. The treatment of fractures in large animals depends on economic value, cost of procedures, prognosis, location and type of fracture. However,although spinal fractures in large animals are not uncommon, the literature about their clinical aspects and treatment isscanty. Therefore, the purpose of this report is to describe a surgical stabilization of atlantoaxial subluxation, fracture ofthe third cervical vertebra and C2-C3 subluxation.Case: An approximately 2-year-old Île-de-France sheep, weighing 101 kg, with a history of cervical trauma and nonambulatory tetraparesis was treated at the Veterinary Hospital of the Institution (UNIPAMPA). During physical examination, the animal presented good general physical condition and heart rate, respiratory rate and temperature was accordingto physiological parameters for the species. The animal remained in lateral decubitus, with minimal head and limb movements, and exhibited deep pain sensitivity. Clinical treatment with dexamethasone, limb physiotherapy and change inlateral decubitus position were employed, but failed to improve the animals condition. After five days of unresponsive toclinical treatment, the patient was referred to the neurology department, where it underwent neurological examination andradiographic examination of the cervical region was performed under general anesthesia. The radiographic examinationrevealed atlantoaxial subluxation, by displacement of the odontoid process into the vertebral canal, fracture of the thirdcervical vertebra and C2-C3 vertebral subluxation. The surgical planning aimed cervical vertebral instability repair usingatlantoaxial arthrodesis associated the stabilization of C1-C2 and C2-C3 vertebrae with Schanz pins and bone cement...(AU)
