Herniated disc

All about herniated discs

In the case of a herniated disc (lat. prolapsus nuclei pulposi, discus prolapse), parts of the spinal column protrude into the spinal nerve or spinal cord canal. The annulus fibrosus and the posterior longitudinal ligament rupture completely, unlike the disc protusion, the protrusion.

Most affected vertebrae are located in the lumbar region; cervical and thoracic vertebrae are less commonly affected. The average age of onset is 40 years.
