A spondylolisthesis refers to a slip of the vertebral body. A spondylolisthesis is not a disc herniation

When the vertebral body slips forward, it causes the nerves in the back to get pinched

Many patients with a spondylolisthesis will need a spinal fusion. In this procedure, a surgeon will place rods and screws in the spine to prevent the slip from occurring. The most common reason why patients undergo a spinal fusion is a spondylolisthesis. 

With endoscopics, some patients with a spondylolisthesis can avoid a spinal fusion procedure. 


This requires a thorough evaluation by a endoscopic spine specialist and a detailed review of a person's history, MRIs, and Xrays.
