Spinal fusion is a surgical procedure that involves joining two or more vertebrae in the spine to alleviate pain, instability, or deformity. It is commonly used to treat conditions such as spinal stenosis, herniated discs, or spinal fractures. During the procedure, bone grafts or synthetic materials are used to help create a solid “bridge” between the vertebrae, promoting fusion over time. This stabilizes the spine, reduces pain, and may also prevent further damage. Rehabilitation and physical therapy are often part of the post-operative recovery process.
