Dr. Timothy Witham is associate professor of neurological surgery and orthopaedic surgery at the Johns Hopkins University School of Medicine. His interests include the surgical treatment of degenerative conditions of the cervical and lumbar spine, including instrumented fusion procedures. He also has an expertise in the treatment of spinal tumors, spinal trauma and spinal deformity.
Dr. Witham serves as director of the Johns Hopkins Neurosurgery Spinal Fusion Laboratory, director of Johns Hopkins Bayview Medical Center's Spine Program and co-program director of the Johns Hopkins Neurosurgery Residency Program.
Dr. Witham received his B.S. in biochemistry from the Pennsylvania State University. He earned his M.D. from the Johns Hopkins University School of Medicine. He completed his residency at the University of Pittsburgh Medical Center. He performed a fellowship in spinal neurosurgery at Johns Hopkins. Dr. Witham joined the Johns Hopkins faculty in 2005.
Prior to joining Johns Hopkins, Dr. Witham was chief neurosurgeon at Keesler Medical Center at Keesler Air Force Base in Biloxi, Mississippi.
Dr. Witham's research interests include finding novel ways to achieve spinal fusion and improving surgical techniques in the aging spine.
A co-author of more than 170 peer-reviewed articles and abstracts, Dr. Witham has been featured as a “Top Doctor” in Baltimore magazine and was a recipient of a United States Air Force meritorious service medal in 2005. He is a member of various professional organizations, including the American College of Surgeons and American Association of Neurological Surgeons.
