Spinal fusion. Spinal fusion, also called spondylodesis or spondylosyndesis, is a neurosurgical or orthopedic surgical technique that joins two or more vertebrae. This procedure can be performed at any level in the spine (cervical, thoracic, or lumbar) and prevents any movement between the fused vertebrae.
Cervical spinal stenosis can also be treated surgically from the back side of the neck. A laminectomy can be performed as in the lumbar spine, but is typically combined with a fusion in the cervical spine to prevent any abnormal motion from instability after the surgery.
