Background: Cervical fractures in dogs occur most commonly in the cranial region, mostly requiring surgery. Various types of implants are being used while fi xation using plate is poorly described in the literature. The plate and screw types are a limiting factor since they can lead to loss of stability due to loosening of the screws. The use of locking plates has been advocated, which does not allow movement between the screw-plate-bone, providing extreme stability and rigidity to the system. This study describes the use of locking bone plate to stabilize axis fracture in a dog and the results obtained with this technique.Case: A 9-month-old male Poodle presented due to a history of trauma to the cervical spine caused by a fall of an object. Upon physical examination, the patient was alert and physiological parameters within the normal reference limits. However, neurological examination showed tetraplegia, hyperrefl exia, preserved nociception and much cervical pain. There were no changes in the cranial nerves test. Cranial cervical lesion was initially suspected and the patient was rigidly fi xed on a flat surface. The radiographic examination showed a fracture of the second cervical vertebra (axis) with anatomical axis deviation, and the patient was referred for surgery. After anesthesia, the dog was positioned dorsal decubitus and rigidly fixed on the operating table with t
