He is a world-renowned pioneer and leader in minimally invasive spinal surgery and computer-assisted spinal navigation surgery. He is actively involved in improving neurosurgical care in developing countries as the leader of Weill Cornell Medicine's Global Health Neurosurgery Initiative in Tanzania.In order to achieve the very best in patient outcomes, Dr. Härtl's practice emphasizes an interdisciplinary approach to disease processes and he works very closely with other specialists such as neurologists, pain specialists, sports medicine doctors and physical therapists. His patients come from all over the globe and include many physicians, surgeons and even other neurological and spine surgeons. He has been repeatedly named to the lists of New York Super Doctors, America's Top Surgeons, and America's Best Doctors, and has been included on the list of New York’s Best Doctors in New York magazine.

In 2004 Dr. Härtl returned to re-join the Department of Neurosurgery at Weill Cornell Medical College.RESEARCHDr. Härtl's scientific interest focuses on clinical and basic science research surrounding innovative and less invasive surgical and biological treatment strategies for degenerative diseases of the spine. Together with the Biomedical Engineering Department at Cornell he is working on tissue-engineering techniques for the repair and regeneration of degenerated spinal discs, the most common cause of back and neck pain. Dr. Härtl has lectured and published extensively on the surgical treatment of spinal disorders, and neurotrauma. He is a leader in the application of evidence-based medicine to neurosurgery and worked with the Brain Trauma Foundation in New York on the development of treatment guidelines for the medical and surgical management of head injury that are now used worldwide.Dr. Härtl sees patients at the Och Spine at NewYork-Presbyterian at the Weill Cornell Medicine Center for Comprehensive Spine Care, at 240 East 59th Street, 2nd Floor.FOR MORE INFORMATION:Please visit comprehensivespine.weillcornell.org for more information about conditions we treat and procedures we perform.
