Posterior Bulging Disc

Posterior Bulging Disc

A posterior bulging disc is a medical term for an intervertebral disc that has bulged toward the “posterior,” or back, of the spinal column. Posterior bulging discs are relatively common, as abnormal disc bulges tend to occur when people are bending forward. This action causes discs to be compressed on the anterior side (stomach side) of the spinal column, causing a protrusion toward the back part of the spinal column.

In order to understand this, let’s examine the structure of the spinal column. The spinal column consists of vertebrae, or bones, stacked up vertically from the base of your neck to your lower back. Between each of these vertebrae are intervertebral discs made up of cartilage and other soft tissues. This flexible material acts like a shock absorber, or cushion, between each of your vertebrae. So, when you sit, stand, bend, run, walk or swing a golf club, your spine can flex and move like it’s supposed to.

As we grow older, the tissues in the discs can lose elasticity. Discs can also be damaged by an injury. Any disc damage or deterioration can cause the disc to weaken and bulge as a person goes about everyday activities, such as bending over and lifting an object. If the bulge is big enough or located in the wrong area, it starts pressing on nerve tissue, causing neck pain, back pain, tingling, numbness and other symptoms. These symptoms can be felt at the site of the posterior bulging disc, or the pain can radiate to other parts of the body, depending on the location of the affected disc in the spinal column.

A posterior bulging disc can be located in any segment of the spinal column that has discs. For instance:

If you believe that you have a posterior bulging disc anywhere along your spinal column, you should visit a physician to learn about your posterior bulging disc treatment options. One of your options may be a minimally invasive procedure performed by the surgeons at Laser Spine Institute.
