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).
When operating from the backside of the spine, the most common method of performing a spinal fusion is to place the bone graft around the back side of the vertebrae. Today, the surgeon will also most likely use some type of metal screws, plates, and rods to hold the vertebrae in place while the spine fusion heals. Special screws called pedicle screws are inserted into the vertebral body.
