What Is a Lumbar Laminectomy?
A lumbar laminectomy is a kind of spinal surgery that relieves pressure on nerves in the lower back. The name comes from the lamina, which is the part of bone at the back of each vertebra.
When spinal stenosis happens, the spinal canal or the spaces where nerves leave the spine can get narrower. This can be caused by bone, thickened ligaments, or other tissues. A lumbar laminectomy removes part of the lamina and, if needed, other tissue that is pressing on the nerves.
The goal is to make more space for the spinal nerves. By taking pressure off a nerve, a laminectomy can help with symptoms like leg pain, numbness, tingling, and weakness.
A laminectomy does not always include spinal fusion. Whether you need fusion depends on your spine’s stability and your specific condition. Dr. Swiatek reviews each case to decide whether decompression alone is enough or whether more support is needed. Dr. Swiatek has extensive laminectomy experience and has performed this non-fusion procedure in many patients who had been recommended a fusion for their lumbar issues.
