Ioannis Alexander Avramis, MD

man_images3Ioannis Alexander Avramis, MD is a board certified, fellowship trained orthopedic spine surgeon. His fellowship training focused on the comprehensive treatment of adult and pediatric spinal conditions. Dr. Avramis treats pediatric and adult patients with cervical and lumbar spinal problems.

Dr. Avramis was born in Houston, Texas and raised in Southern California. He earned his bachelor’s degree from UCLA and graduated Summa cum Laude. He completed medical school at UC Davis in Sacramento, California. He completed his orthopedic surgery residency at USC + Los Angeles County Hospital and went on to receive additional specialized training in adult and pediatric spinal surgery during his fellowship at UC Davis Medical Center and Shriners Hospitals for Children Northern California.

When searching for a practice, Dr. Avramis wanted to be affiliated with a spine center that focused on the comprehensive, evidence based approach to treatment of children and adults with cervical and lumbar spinal conditions. He found that commitment to research based approach combined with proven outcomes at the Southwest Scoliosis Institute. Dr. Avramis, “wanted to be part of a team that provided the highest quality treatment for spine patients in a supportive environment that also furthered the treatment of spinal conditions through research and the development of innovative techniques.”

Dr. Avramis is involved in the advancement of the field of spinal surgery through research, publication and membership in various societies such as the American Academy of Orthopaedic Surgeons and the North American Spine Society. In addition to the book chapters and research projects he has published, Dr. Avramis is interested in developing tools and techniques to allow patients to have a more successful and less painful surgical experience.
