Abstract

An eight-year-old, castrated male, Poodle dog was presented with a bite wound in the neck region. Clinical examination revealed non-ambulatory signs of tetraparesis with deep pain, and upper motor neuron changes in all limbs. Fractures of the transverse process of C1 and the dorsal spinous process of C2 were observed on the radiographs and the computed tomography (CT). Conservative therapy was performed for 1 week. However the neurological problems were not alleviated until 7 days after injury. The owners agreed to perform surgical stabilization. The surgical stabilization was performed 7 days after presentation. Ventral stabilization was performed with screws, K-wires and bone cement. The dog stood up independently after 4 weeks and was able to walk 6 weeks postoperatively. In this report we suggest that using combined stabilization techniques are effective for this type of cervical fracture in which the dorsal and ventral structures of the vertebra are severely disrupted.
