Nicholas Theodore, M.D., director of the Johns Hopkins Neurosurgical Spine Center, is a nationally recognized expert in brain and spinal cord injury, minimally invasive spine surgeries and robotics. He earned a medical degree at Georgetown University School of Medicine and completed both a residency in neurosurgery and a fellowship in spinal surgery at the Barrow Neurological Institute.
As an award-winning teacher and researcher, Dr. Theodore has written or co-authored 30 book chapters, over 180 peer-reviewed journal articles and is co-holder of 10 patents for medical devices and procedures. His research focuses on trauma, spinal cord injuries, robotics and developing an understanding of the genetic and molecular basis of spinal diseases.
Dr. Theodore treats patients with a variety of spinal disorders including, trauma, Chiari malformations, spinal deformities, degenerative spine conditions and spinal cord tumors. He sees patients at both the Johns Hopkins Outpatient Center and the Johns Hopkins Bayview Medical Center.
