Spinal Fusion Benefits Spinal fusion benefits often help alleviate pain from compression of spinal nerves due to excessive vertebral motion or slippage. The majority of patients who undergo a laminectomy with spinal fusion experience considerable relief from back pain symptoms from conditions such as spinal stenosis (Houten, 2003).
Why It Is Done. Cervical spinal fusion may be done: 1  After an injury, to stabilize the neck and prevent a bone fracture from causing instability or damage to the spinal cord, which may result in paralysis.2  To treat conditions such as misalignment of the vertebrae. The bone is used to make a bridge between vertebrae that are next to each other (adjacent). 2  This bone graft stimulates the growth of new bone. 3  Man-made (artificial) fusion materials may also be used. 4  Metal implants can be used to hold the vertebrae together until new bone grows between them.
