A spinal fusion is a surgery to weld together two vertebrae, the bones that make up the spine.
Anterior spinal fusion
A fusion can be performed on a smaller portion of the spine from the side of the body. This approach leaves a less noticeable scar for the patient and preserves more flexibility of the spine after surgery. Only a select amount of curves can be corrected with this technique.
Lumbar spinal stenosis
This surgery is done to relieve pressure on the nerve roots. This can help reduce pain, numbness, and weakness in your legs.
A decompression surgery involves removing a small portion of the bone over the nerve root and/or disc material from under the nerve root to relieve pinching of the nerve and provide more room for the nerve to heal. The most common types of decompression surgery are microdiscectomy and laminectomy.
In this type of lumbar decompression surgery the part removed is called the lamina; the part removed is above and below a pinched nerve. In some cases, only a portion of the lamina is removed from the vertebra.
