Laminotomy

Laminotomy is the surgical incision and removal of a small part of a bony area of the spine called the lamina. The lamina is the back part of each vertebra and forms the back wall of your spinal canal. Your spinal cord runs through your spinal canal in the center of your vertebrae. Certain conditions of the spine can compress the spinal cord and cause pain. A laminotomy can relieve pressure in your spinal canal and on spinal nerves.

The word laminotomy is often used interchangeably with laminectomy. However, in a laminotomy only a small part of the lamina is removed, while in a laminectomy most of the lamina is removed.

Laminotomy is a common but major surgery with significant risks and potential complications. You may have less invasive treatment options available depending on your specific circumstances. You should consider getting a second opinion about all your treatment choices before having a laminotomy.
