What is a Lumbar Laminectomy?

Lumbar Laminectomy

Medical terminology doesn’t go out of its way to be complicated or hard to understand. It’s simply that the language has to be very precise, and that much of it comes from Latin. Hence, it can be difficult to decipher some med-speak without a little help. Take the term “lumbar laminectomy,” a fairly common surgical procedure that can help alleviate the pain, mobility limitations and other symptoms that often accompany medical conditions of the lower spine. Indeed, the word “lumbar” refers to the lower spine. The lumber portion of the spine comprises the lowest five vertebrae of the spinal column, which bear the designation L1 through L5 – “L” standing for lumbar.

Every vertebra in the spinal column is covered in a bony sheath called the lamina, which helps protect

the nerves that run through the spinal column. But sometimes, due to injury, disease, degenerative changes, or other causes, the lamina can put pressure on nerves emanating from the spinal column, a condition referred to as a pinched nerve. Problems within the vertebrae, such as an unnatural narrowing of the spinal canal, a condition called spinal stenosis, can also result in pinched nerves.

When surgery is performed to relieve pressure on a pinched spinal nerve, a procedure called spinal decompression, it requires cutting away the portion of the lamina that is impinging on a nerve, or to gain access to the interior of the vertebrae t

o address a condition such as spinal stenosis. In medicine, the suffix “ectomy” refers to excision or removal. Thus, cutting away a portion of the lamina is a procedure called a laminectomy. So a lumbar laminectomy is an operation in which a portion of the lamina on one of the first five vertebrae is trimmed away. A lumbar laminectomy can achieve dramatic results in alleviating the symptoms of pinched nerves. Traditionally, spinal fusion back surgery was performed in concert with a laminectomy to stabilize the spine at the point of the operation. Now lumbar laminectomy patients have an alternative that provides better outcomes than spinal fusion surgery, while preserving the full range of the spine’s motion: The TOPS (Total Posterior Spine) System procedure. If you’re a candidate for a lumbar laminectomy or other spinal decompression procedure, make sure you understand all your treatment options.
