- Disk Prolapses
- Disk Prolapses / Spinal Disk Protrusions
Spinal or lumbar disks are very forgiving yet can also cause problems. When, for example, the fibrous ring (annulus fibrosus) surrounding the intervertebral disk moves axially or laterally, this is called a disk protrusion. In cases where the gelatinous, spongy center presses down on the fibrous ring so hard that it tears, we are talking about a herniated disk (prolapse). When gelatinous substance mass already escapes the fibrous ring and enters the spinal canal, we are looking at a sequestered disk prolapse.
