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).
As with all spinal fusion surgery, a posterior lumbar interbody fusion (PLIF) involves adding bone graft to an area of the spine to set up a biological response that causes the bone to grow between the two vertebral elements and thereby stop the motion at that segment.
