Herniated disk. A herniated disk is a protrusion of the disk’s gelatinous center, called the nucleus pulposus, which often pushes into the spinal cord or spinal nerves to cause pain and loss of movement (left illustration). The illustration on the right shows the back surgery necessary to access the injury.
