Christopher Ames MD

Professor of Clinical Neurological Surgery and Orthopaedic Surgery

Director of Spine Tumor & Spinal Deformity Surgery

Co-director, Spinal Surgery and UCSF Spine Center

Director, Spinal Biomechanics Laboratory


Dr. Ames is the director of spinal deformity and spine tumor surgery and co-director of the combined high risk spine service, the Neurospinal Disorders Program, and the UCSF Spine Center. He is board certified in neurosurgery. He was named to the 2015 and 2016 Top Doctors lists in San Francisco Magazine, and among America’s Top Doctors for both neurosurgery and cancer from 2010 to 2016. His tumor practice focuses on en bloc tumor resection for chordoma, chondrosarcoma, giant cell tumor, soft tissue sarcoma, sacral tumors, and other primary and metastatic tumors. While at UCSF, Dr. Ames developed and published the transpedicular approach to previously unresectable cervical and cervical thoracic tumors.

Dr. Ames serves as the UCSF site director for the International Spinal Deformity Study Group and the AO Scoli-Risk Study. He also directs the neurosurgical spinal deformity service, which performs over 200 cases per year for correction of scoliosis, kyphosis, flat back, and chin-on-chest deformity in ankylosing spondylitis. His research work in spinal deformity has won the prestigious Hibbs award, as well as the Moe award, the Goldstein award, and Whitecloud awards from the Scoliosis Research Society. Dr Ames developed and published the first ever classification for cervical spine deformity and cervical osteotomy with the international spine study group.

He is internationally recognized for his work in spine tumor, deformity, and scoliosis and cervical kyphosis and has published over 300 peer-reviewed publications. He has been the honored international guest lecturer of the Australian Spine Society, the Argentine Spine Society, the Kuwait Neurosurgical Society, the Korean Spine Society, and the Asian Pacific Spine Society. He has served as chairman for over 40 national courses to teach advanced tumor and deformity techniques to neurosurgeons and orthopedic surgeons and has been visiting professor at Cedars Sanai, University of Southern California, and Massachusetts General Hospital.

In 2005, Dr. Ames was sought out by the NBC show "Three Wishes" to perform surgery for a patient with severe scoliosis. Although she had been previously told that she would remain permanently paralyzed, the operation allowed her to walk again. For more information, see the The Daily Star's report: Local Woman Gets Wish, Walks Again

Dr. Ames was also featured on abc 7 when he performed a ground-breaking surgery to remove a spinal cord tumor from a patient in Northern California. Read the story here.
