Dr. Radcliff was recently chosen as the liaison of the American Academy of Orthopedic Surgeons to the North American Spine Society Low Back Pain Guideline Committee.

Dr. Radcliff regularly teaches other surgeons at national and international meetings about safely and efficiently performing spine surgery, techniques and complication avoidance in minimally invasive spine surgery, orthopedic basic science, and spine trauma and spinal cord injury.

Dr. Radcliff is incoming Chairman of the North American Spine Society Young Surgeons Forum. Dr Radcliff is President of the Association for Collaborative Spine Research.  Dr. Radcliff is a regular invited faculty member at numerous national and international spine meetings including the prestigious “Contemporary Techniques in Minimally Invasive Cervical and Lumbar Spine Surgery” course in St. Louis. Dr Radcliff is also on the faculty at the Cervical Spine Research Society meeting, Association for Neurological Surgeons/Congress of Neurological Surgeons Joint Meeting on Spine, North American Spine Society, and American Academy of Orthopedic Surgeons.
