Herniated Disc of the Lumbar Spine

The bones (vertebrae) that form your spine are cushioned by round, flat discs. When these discs are healthy, they act as shock absorbers for the spine and keep the spine flexible. If they become damaged, they may bulge abnormally or break open (rupture), in what is called a herniated or slipped disc.

Although herniated discs can occur in any part of the spine, one of the most common areas is the lower back (lumbar) area. A herniated disc can also occur in the neck (cervical herniated disc) and upper back, which is referred to as a thoracic herniated disc.
