Lumbar Laminectomy Indications in Portland, Oregon

What is a Lumbar Laminectomy?

A laminectomy is an operation to expose the spine over the nerves. As the name implies, laminectomy means removing the lamina, which is the bony covering to the nerves in the back of the spinal column. In so doing it is a treatment because un-roofing the nerves relieves the pressure upon them.

What Are the Indications for Performing a Lumbar Laminectomy?

Laminectomy is usually used to treat spinal stenosis. Spinal stenosis is a condition in which there is nerve impingement due to bone spurs, thickened ligaments, or bulging discs. In the process of the laminectomy, these offending structures are removed, therefore freeing up the nerves.

Most patients with spinal stenosis present with buttock, hip, or leg pain and frequently difficulty standing for a period of time or walking. If your pain is mild or moderately tolerable we do not recommend you proceed with surgery.

What are the Details of Lumbar Laminectomy?

After general anesthesia is obtained patients are carefully placed on a frame and secured in the prone position. X-ray imaging is used to localize the proper level for surgery and an incision is made over the lamina. The muscles on both sides of the spine are pushed to the side and the lamina is then removed, taking care to preserve the facet joints which provide stability for the spine.
