The surgical option for a person with spinal stenosis usually involves a procedure called decompressive laminectomy with an option to perform a spinal fusion, according to WebMD. These procedures relieve pressure on the back, specifically the spinal nerve roots.
Decompressive laminectomy involves removing parts of the vertebrae or thickened tissue surrounding the spine, states WebMD. Sometimes, a doctor opts to perform a spinal fusion, which helps stabilize the part of the spine that underwent the decompressive laminectomy. The most common way to perform a spinal fusion is to take bone, either from the individual or from a bone bank, and create a "bridge" by placing this piece between two vertebrae. This stimulates the bone to grow, adding support.
