Spinal fusion is a surgical procedure done for correct issues with the tiny bones within the spine (vertebrae). The most common treatable disease with this procedure is spondylolisthesis or slip disc. The core idea is to fuse together two or more vertebrae so that they heal into a single vertebra, solid bone. This fusion helps in the elimination of painful motion or to restore stability to the spine. The spinal fusion prevents the stretching of nerves, surrounding ligaments and muscles.
It becomes a very good option when motion is the main cause of pain, such as movement that occurs in a part of the spine that is arthritic or unstable due to injury, disease, or because of the normal ageing process.
