IN THE NEWS:Dr. Härtl Named One of America's Top Spine SurgeonsDr. Härtl Selected to New York SuperDoctors 2024Dr. Härtl Named to Castle Connolly's 2024 List of Top DoctorsDr. Härtl's clinical interest focuses on simple and complex spine surgery for degenerative conditions, tumors and trauma as well as biological approaches for disc repair and regeneration. 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. He has authored more than 200 scholarly articles in peer-reviewed journals and is the editor of two books on minimally invasive spinal surgery and biological disc repair and regeneration.Dr. Härtl has provided commentary for numerous television shows on ABC, NBC, and CBS in addition to national radio shows. His expertise has been sought through interviews in the New York Times, The New York Post, The New York Daily News, and other media outlets. One of his patients, boxer Danny Jacobs, was recently featured in a TV ad from NewYork-Presbyterian.TRAINING Dr. Härtl received his M.D. from the Ludwig-Maximillians University in Munich, Germany. In 1994 Dr. Härtl came to the Weill Cornell Medical College as a post-doctoral research fellow in the Department of Surgery and the Brain Trauma Foundation to pursue research in traumatic brain and spinal cord injury. He completed another fellowship in neurocritical care at the Charite Hospital of the Humboldt University in Berlin, Germany, followed by a surgical internship and residency at Allegheny General Hospital in Pittsburgh, Pennsylvania. He completed his neurosurgery residency at NewYork-Presbyterian/Weill Cornell Medical Center and Memorial Sloan-Kettering Cancer Center, after which he pursued specialized training in complex spine surgery at the Barrow's Neurological Institute in Phoenix under Dr. Volker Sonntag. 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.
