Schmorl's Node: An Uncommon Case of Back Pain and Radiculopathy.

Background: Schmorl's nodes are herniations of nucleus pulposus through the cartilaginous and bony endplate into the adjacent vertebra. Schmorl's nodes are extremely common and are typically seen as incidental findings on radiographic imaging. In postmortem studies, it has been estimated that greater than 70% of the population has Schmorl's nodes.
