The Disc

A Healthy Disc

Your backbone, or spine, is made up of 26 bones called vertebrae. In between them are soft disks filled with a jelly-like substance. These disks cushion the vertebrae, keep them in place and act as shock absorbers for the spine.

A Bulging Disc

Bulging 20Disc 201

A bulging disk is a condition related to the spine, that occurs when a disk bulges through a crevice in the spine. A bulging disk occurs when the disk shifts out of its normal radius and most often occurs simply as a result of age. In many cases, a bulging disk may be diagnosed as a condition secondary to another problem. Because a bulging disk does not always cause pain, it may only be found during a routine or diagnostic imaging test such as magnetic resonance imaging (MRI). Typically, a bulging disk is not a problem unless it begins to cause pain, becomes herniated or ruptures.

A Herniated Disc

Herniated disks are also called ruptured disks or slipped disks. A herniated disk is a disk that slips out of place or ruptures. If it presses on a nerve, it can cause back pain or sciatica. Herniated disks are more likely to cause pain.
