Neurosurgery is a surgical specialty (children - a Pediatric Neurosurgeon) with the medical doctor acquiring additional qualifications enabling specialization in the surgical management of diseases of the central nervous system including the brain and spinal cord, the peripheral nervous system, and autonomic nervous system, the support structures of these systems (meninges, skull, and vertebrae), as well as the related blood vessels. Conditions treated include such compressed nerves in the back or neck, tumors, damage to the brain or spine from an injury; and the operative and non-operative management of pain control.  Surgical procedures include endovascular surgery, functional and restorative surgery, stereotactic radiosurgery, and spinal fusion—including its instrumentation. Treatment also encompasses associated image use and interpretation (CT, MRI), neuro-critical intensive care and rehabilitation.
