Biography

Dr. Ali Bydon is an Associate Professor of Neurosurgery at Johns Hopkins. His busy clinical practice focuses on degenerative disorders of the spine, spinal tumors, and complex reconstruction and restoration of the spine. Dr. Bydon is certified by the American Board of Neurological Surgeons, is a member of the American Association of Neurological Surgeons and the Congress of Neurological Surgeons. 

Dr. Ali Bydon earned his medical degree from the University of Michigan School of Medicine in Ann Arbor. He completed residency training in Neurological Surgery at the Henry Ford Hospital in Detroit, where he graduated with distinction in 2006. He also completed a fellowship in Minimally Invasive Spine Surgery at Henry Ford, as well as a fellowship at Louisiana State University on the Surgical Treatment of Peripheral Nerves. Dr. Bydon then completed a one-year instructorship in Spinal Oncology and Complex Reconstructive Spinal Surgery at The Johns Hopkins Hospital.

Dr. Ali Bydon is the director of the Spinal Column Biomechanics and Surgical Outcomes Laboratory at Johns Hopkins. His research focuses on spinal biomechanics, spinal disparities and surgical outcomes. He has co-authored over 120 peer-reviewed manuscripts and numerous book chapters. Dr. Bydon co-authored the largest series in the literature evaluating the best surgical approach to spinal synovial cysts.  His seminal work on outcomes after lumbar disk surgery has earned over 100 citations. The Spinal Outcomes Laboratory that he directs continues to evaluate multiple projects related to outcomes of patients with BMP, cervical myelopathy, cervical radiculopathy, ossified posterior longitudinal ligament, minimally invasive diskectomy, lumbar fusion techniques and degenerative scoliosis. He is widely on the history of spine surgery, the outcomes of patients after cervical, thoracic, and lumbar surgery, disparities in accessibility to care, and outcomes of patients with spinal tumors. His work has led to over 100 presentations at national and international scientific meetings.  He has been invited to speak at meetings in Korea, Spain, Italy, Saudi Arabia, Lebanon, Syria, Panama, Kuwait, Qatar, Brazil, Bermuda, Dominican Republic and elsewhere.

Dr. Bydon is a principal investigator of several national, multi-center, prospective clinical trials evaluating long-term patient reported  outcomes following spine surgery. Dr. Bydon serves as a reviewer for a dozen scientific publications, including Spine and Neurosurgery.

Dr. Bydon is an educator who has helped train over 30 currently-practicing neurosurgeons. He is the recipient of the prestigious Richard Otenasak Faculty Teaching Award (2011) and serves as the co-director of Neurosurgical Medical Student Education. He has received Maryland’s “Favorite Physician” yearly award since 2008. Dr. Bydon serves on the Johns Hopkins Department of Neurosurgery Residency
Review Committee, and the Patient Access Committee. He was recently elected as the neurosurgical representative on the Johns Hopkins Faculty Senate. 

Dr. Bydon sees patients on Wednesdays at the Johns Hopkins Outpatient Center and on Mondays at the Johns Hopkins Bayview Medical Campus.

    Research Summary

    Dr. Bydon’s research focuses on the biomechanical properties of complex spinal reconstructions. As the director of the Spinal Column Biomechanics Laboratory and Surgical Outcomes Laboratory, Dr Bydon biomechanically validates the strength of alternative in vitro instrumented constructs and applies this technology into clinical practice with controlled outcomes assessment. In addition, he focuses on the development of novel plate systems to minimize graft subsidence in anterior spinal constructs.

    Lab

    Dr. Ali Bydon is the director of the Spinal Column Biomechanics Laboratory and Surgical Outcomes Laboratory at Johns Hopkins. His research focuses on spinal biomechanics, spinal disparities and surgical outcomes. He has co-authored over 120 peer-reviewed manuscripts and numerous book chapters. Dr. Bydon co-authored the largest series in the literature evaluating the best surgical approach to spinal synovial cysts.  His seminal work on outcomes after lumbar disk surgery has earned over 100 citations.

    The Spinal Outcomes Laboratory that he directs continues to evaluate multiple projects related to outcomes of patients with BMP, cervical myelopathy, cervical radiculopathy, ossified posterior longitudinal ligament, minimally invasive diskectomy, lumbar fusion techniques and degenerative scoliosis. He is widely on the history of spine surgery, the outcomes of patients after cervical, thoracic, and lumbar surgery, disparities in accessibility to care, and outcomes of patients with spinal tumors. His work has led to over 100 presentations at national and international scientific meetings.  He has been invited to speak at meetings in Korea, Spain, Italy, Saudi Arabia, Lebanon, Syria, Panama, Kuwait, Qatar, Brazil, Bermuda, Dominican Republic and elsewhere.
