Laminectomy is a surgical procedure to relieve pressure on the spinal cord or spinal nerve roots which is caused by spinal stenosis. Spinal stenosis is narrowing of the spinal canal that puts pressure on the spinal cord, which is filled with nerves. This causes pain, numbness, or weakness in your legs, back, neck and arms.
The procedure involves surgery to your back to remove the bone and/or tissue that is causing the pressure on the spine. Laminectomy can also be used to treat spinal injuries, herniated discs (commonly known as slipped discs) and spinal tumours.
