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).
