WHAT IS SPINAL STENOSIS?
Spinal stenosis is a condition, mostly in adults 50 and older, in which your spinal canal starts to narrow. This can cause pain and other problems. Spondylosis also can cause spinal stenosis
WHAT ARE THE TYPES OF SURGERIES?
Following options are considered by spinal surgery doctors:
- Decompression: Decompression is a term that describes surgical techniques designed to relieve pressure from nerves or the spinal cord
- Laminotomy and Foraminotomy: If stenosis primarily affects the foramen—an opening in the vertebra through which nerves travel outward from the spinal canal—doctors can surgically widen the foramen and relieve pressure on the nerves. Often, doctors first remove part of the bony “roof” of the vertebra—called the lamina—to better access the spinal canal during surgery. These procedures are called laminotomy and foraminotomy.
- Laminectomy: Laminectomy involves removing the lamina, the part of each vertebra that forms the “roof” of the spinal canal. Removing the lamina from the affected vertebrae creates more space in the spinal canal and reduces pressure on the nerve roots and spinal cord. During laminectomy, a surgeon may also remove any bone spurs that have accumulated due to osteoarthritis. The surgeon may trim parts of the facet joint—located just above the lamina—if it has become inflamed due to arthritis and is compressing nearby nerves. Removing a large part of one or more facet joints may destabilize the spine. If this happens, surgeons may elect to perform a spinal fusion in addition to a laminectomy to ensure that the spine heals correctly and to reduce the risk of further problems.
- Discectomy: Discectomy involves removal of the injured part of a bulging or herniated disc, relieving pressure on the nerves or spinal cord. This may be an open procedure, allowing direct access to the disc through an incision, or a minimally invasive procedure called microdiscectomy, allowing access to the disc through smaller incisions and use of tiny surgical instruments. Either technique may be used to remove a disc fragment in the lower spine or neck.
- Spinal Fusion: In spinal fusion, a surgeon permanently joins unstable vertebrae using metal screws and rods. These remain in your spine and act like an internal brace to keep the bones in the correct position. The surgeon can also insert a small piece of living bone material, called a bone graft, between the joined vertebrae. This bone graft may be taken from your own body, typically from the hip, or from a donor through a bone bank. The graft may be placed directly between the fused vertebrae or inside a small metal cage before placement in the spine, which provides additional stability. Over time, the joined vertebrae heal, fusing into one bone mass. This gives the spine the stability and flexibility needed to support the body and also eliminates pain caused by the slipped vertebra pushing against nerve roots or the spinal cord. During spinal fusion, the surgeon may also widen the foramen, trim the facet joints, remove some or all of a herniated disc, or remove bone spurs.
