Abstract

|
|
A nine-month-old male Pekingese weighing 5.7 kg was admitted to the Veterinary Medical Center at Chungbuk National University with a history of acute nonambulatory tetraparesis after minor trauma. A diagnosis of atlantoaxial instability with a dens axis fracture was based on examination of survey spinal radiographs and was confirmed during surgery. A modified ventral fixation technique using cortical screws was used for stabilization of the atlantoaxial joint. Serial evaluation based on radiographic and neurologic assessment was performed eight weeks after surgery. Symptoms of tetraparesis disappeared gradually, and arthrodesis of the atlantoaxial joint using a ventral fixation technique has maintained stable fixation.
