Dr. Lanman is a board-certified neurosurgery specialist practicing medicine for 25 years with a private practice in Beverly Hills, CA. He specializes in treating spinal disorders and is a leading clinical advocate for artificial disc replacement and motion preservation surgery. Dr. Lanman has led many clinical trials to study artificial disc replacement for the spine's cervical and lumbar regions. Artificial Disc Replacement (ADR) replaces degenerated or damaged discs with an artificial one that moves and allows your spine to flex as it is intended. Previously, sufferers of painful conditions like degenerative disc disease had spinal fusion as their only surgical option. By fusing the spine, the patient loses range of motion and flexibility. Lanman Spinal Neurosurgery is focused on motion preservation; that means we avoid procedures like spinal fusion. Decades of clinical studies have shown that artificial disc replacement is the better treatment option.
