Disc Herniation V. Bulging Disc
Disc herniation and bulging disc are all injuries that can be caused by a car accident. This article will take a look at the topic: Disc Herniation V. Bulging Disc; i.e. what disc herniation and bulging disc are.
Between the vertebral bones and spine are intervertebral discs. These discs act as cushioning and/or shock absorbers for the spine. Each disc is made of two parts:
- The nucleus the nucleus is what makes up the center of the disc. It is spongy and is what gives the disc its shock absorber ability
- The annulus the annulus holds the nucleus in place. It is made up of a series of strong ligament rings that are around the nucleus.
Disc Herniation V. Bulging Disc: Disc herniation
Disc herniation happens when the nucleus pushes out of its normal place; that is the center of the disc. The nucleus presses against the annulus causing the disc to slip forward/outward. The nucleus pushes completely through the annulus and squeezes out of the disc which is disc herniation. A relatable simile of disc herniation is that of a jelly donut if squeezed the jelly breaks out of the outer part of the donut and oozes out.
In car crashes, disc herniation happens from a sudden jerking movement which puts a lot of pressure on a disc.
Disc Herniation V. Bulging Disc: Bulging disc
A bulging disc extends outside the space it should normally occupy. The damage to the disc causes the nucleus to be squeezed but not to the point of bursting out of the annulus. The nucleus remains within the annulus, thus the disc remains intact with only a small bubble making a lump on the annulus. The effect is that the disc sticks out of the spinal canal. In car crashes, the sudden jerking movement puts pressure on the disc and squeezes it out of its natural position causing a bulging disc.
