What is the primary purpose of spinal fusion surgery?

The primary purpose of spinal fusion surgery is to permanently join vertebrae and stabilize the spine. This surgical procedure is often indicated in cases where patients suffer from unstable spinal conditions, such as a herniated disc, degenerative disc disease, spinal deformities, or following spinal fractures. By fusing the vertebrae together, the surgery aims to eliminate motion at the affected segment of the spine, which can help alleviate pain caused by abnormal movement or instability.

This permanent stabilization helps to create a solid mass of bone where the vertebrae have been fused, ultimately improving overall spinal alignment and function. In addition to providing pain relief, the procedure can also prevent further degeneration of the spine and reduce the risk of subsequent issues arising from instability. Hence, spinal fusion is a critical intervention for maintaining structural integrity and stability in patients with serious spinal conditions.
