Lumbar spine disc herniation is the disruption of the integrity of the normal intervertebral disc, the pad of cartilage that sits between the vertebral bones of the spine.
Mild disruption of the disc may result in lumbar disc degeneration.
More disruption of the disc may result in pain into the leg or foot called sciatica.
More serious disruption of the disc may result in a contained lumbar disc herniation or a non-contained lumbar disc herniation.
Check out what happens to the disc as it degenerates and herniates.
