Your doctor may recommend an operation to remove the disc–the spongy cushion that sits between each bone of the back. This step is called a discectomy. (“Ectomy” means to remove.) If there is still too much pressure on the nerves within the spinal canal, the doctor may remove a section of the bone that covers the back part of the spinal column over the injured disc (the “lamina”). This part of the operation is called a laminectomy.
