What is the main purpose of spinal fusion surgery?

The primary purpose of spinal fusion surgery is to stabilize the spine. This procedure involves the fusion of two or more vertebrae together, which can help to eliminate motion at that segment of the spine. Such stabilization is often necessary in cases where there is instability due to conditions such as degenerative disc disease, spinal fractures, or diseases like scoliosis. By fusing the vertebrae, the surgery aims to create a solid bony union that can support the spine, thus preventing further pain or deformity.

While relief of pain can be a benefit of spinal fusion, its main goal is to achieve stability. Increased flexibility and greater mobility are not outcomes typically associated with spinal fusion, as the procedure inherently involves limiting motion in the fused segment.
