Lumbar Laminectomy

Lumbar laminectomy is a surgical procedure most often performed to treat leg pain related to herniated discs, spinal stenosis, and other related conditions. Stenosis occurs as people age and the ligaments of the spine thicken and harden, discs bulge, bones and joints enlarge, and bone spurs (called osteophytes) form. Spondylolisthesis (the slipping of one vertebra onto another) can also lead to compression.

The goal of a laminectomy is to relieve pressure on the spinal cord or spinal nerve by widening the spinal canal. This is done by removing or trimming the lamina (roof) of the vertebrae to create more space for the nerves. A surgeon may perform a laminectomy with or without fusing vertebrae or removing part of a disc. Various devices (like screws or rods) may be used to enhance the ability to obtain a solid fusion and support unstable areas of the spine.
