Neurosurgery: The spinal cord is a vital structure which unlike other organs, has a limited ability to repair itself. Animals affected with cervical vertebral instability (Wobblers Disease), atlanto-axial subluxation-equina syndrome, cervical and thoraco-lumbar intervertebral disk herniation, spinal tumors, and vertebral fractures are among those patients for whom neurosurgery offers the best chance of recovery.
