Bulging Discs vs. Herniated Discs

The primary difference between bulging discs and herniated discs are whether they are contained or non-contained:

Contained vs.
Non-Contained
Disc Disorders

A contained disc — such as a bulging disc — has not broken through the outer wall of the intervertebral disc, which means the nucleus pulposus remains contained within the annulus fibrosus.

A non-contained disc — such as a herniated or ruptured disc — has either partially or completely broken through the outer wall of the intervertebral disc.

A bulging disc may be a precursor to a herniation. The disc may protrude into the spinal canal without breaking through the disc wall. The gel-like interior (nucleus pulposus) does not leak out. The disc remains intact except a small bubble appears on the outside of the disc.

When a disc herniates, the contents may compress the spinal cord or the spinal nerve roots. To complicate matters, sometimes fragments from the annulus (the outer disc wall) may break away from the parent disc and drift into the spinal canal.
