CNSO Conditions for Spine and Brain SurgeryIn order to provide an accurate diagnosis with the most effective treatment option for “back problems” and brain tumors, CNSO is led by neurosurgeons and orthopedic spine surgeons. Neurosurgeons are the experts of the nervous system which includes the brain and the spine. Both neurosurgeons and orthopedic spine surgeons are trained in the biomechanical bone structure of the spine called the vertebral bones. Under the care of our award-winning neurosurgeons and orthopedic spine surgeons, Northern NJ patients can have the confidence that their medical condition will be handled with consideration for their comfort and long-term well-being as well as technical excellence.
