A lumbar discectomy is a surgical procedure in which the herniated portion of an intervertebral disc is removed. This procedure is used when the disc is causing pain by bulging into the spinal cord or radiating nerves. A laminectomy is often involved to permit access to the intervertebral disc in a traditional discectomy. This can allow the physician better access. The goal of this procedure is to decrease pain and allow for better movement and function. In addition, removing the herniated portion of the disc decreases the chances that the disc will herniate again.
