Spinal fusion is surgery to connect two or more bones in any part of the spine. Connecting them prevents movement between them. Preventing movement helps to prevent pain. During spinal fusion, a surgeon places bone or a bonelike material in the space between two spinal bones. Metal plates, screws or rods might hold the bones together. They then can fuse and heal as one bone.
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, lumbar, or sacral) and prevents any movement between the fused vertebrae. There are many types of spinal fusion and each technique involves using bone grafting—either from the patient (autograft), donor (allograft), or artificial bone substitutes—to help the bones heal together.
