What is a Lumbar Laminectomy?
Lumbar laminectomy is a surgical procedure performed to alleviate pain from lumbar spinal stenosis. The procedure involves removing the lamina, or the back part of the vertebrae covering spinal canal. This surgery is also known as decompression surgery. By removing the lamina, it creates more space for the spinal canal and decompresses the nerve roots that may be causing conditions such as sciatica. Spinal stenosis is a narrowing of the spinal canal due to disease processes such as arthritis or bony overgrowths, as well as degenerative changes that result in enlargement of the facet joints.
Why Is a Lumbar Laminectomy Performed?
A laminectomy is often done to relieve the effects of spinal stenosis. In this condition, your spinal column narrows and puts pressure on the spinal cord or nerves. A laminectomy is performed while you are under anesthesia. You’ll be asleep during the procedure if you have general anesthesia, or you’ll be awake if you have spinal anesthesia. Either way, you will feel no pain during the procedure. Your anesthesiologist will monitor you throughout the surgery.
