An illustration of a posterolateral herniation of an intervertebral disk in the lumbar spine. Individuals suffer from a herniated disk when the outer fibrous tissue of the disk, known as the anulus fibrosus, can rupture due to trauma or old age. As a result, the gel-like center of the disk protrudes outward and compresses the nerves in the back, weakening muscles and causing severe local back pain.
