A laminectomy is the surgical removal of the lamina of the vertebrae. Most commonly the goal of a laminectomy is to alleviate pain caused by neural impingement that can result from spinal stenosis (usually bony spicules that narrow the canal and press on the spinal nerves).

Reasons a laminectomy is performed:

  • A disc fragment
  • decompressing the spinal cord
  • accessing the spinal cord
  • An osteophyte or bone spur
  • Protruding/degenerating discs
  • Facet arthritis and/or cysts
  • Tumors
