The intervertebral disc is a shock absorber/cushion between the bones in the spine that allows us to move and bend. It is made up of a rough outer ring (annulus), with a softer material (nucleus pulposus) inside. A herniated disc, also called a "slipped" or "ruptured" disc, is the result of a tear in the outer layer of the disc; due to that tear, a portion of the softer material is pushed out. This material can then contact the nearby nerves, causing pain, numbness, or weakness in the arms and legs. It can happen in any part of the spine, but is most common in the lumbar (lower back) or cervical (neck) regions of the spine. It’s a common occurrence in all ages, and happens in men, women, and children.
