When looking at the lumbar spine, you will note that between each vertebra is a block of tissue that resembles a hockey puck. This "tissue" is actually a shock absorber that cushions the stress on the spine with bending, twisting, lifting, etc. It has a central area of extremely tough protein-gelatin like material that is the cushioning part. This gelatin material is surrounded by a ring of thick material that is called the annulus and is layered much like a tire. Think of the outer portion of the annulus as the tread of a tire. There are blood vessels and nerves in the outer layers of this "ring" of tissue. As we get older the central gelatin material begins to dry out and the bending, twisting, heavy lifting begins to put more pressure and weaken this outer ring of fibers. They can actually tear from stress, resulting in a significant amount of pain (picture this as occurring in the center area of the "tread")... When rupturing of this annulus occurs and the thick gelatin material pushes out beyond the annulus we call this a herniated disk. If the material remains within the annulus and doesn’t travel beyond the broad ligament that travels down between the spine and the spinal cord, it is considered “subligamentous”… So, this report is saying that you have a degenerated disc, but it's not pressing on the spinal cord or a nerve root...

What effects do you get from moderate central canal stenosis due to a broad-based right paracentral 4mm disc protrusion at C5-6?

There are a lot of folks walking around with a c-spine herniated nucleus pulposis (HNP) and don't know it until for some reason an MRI is ordered...!! What would tell me to

What is paracentral disc protrusion?

Paracentral disc protrusion is a disorder of the spine that causes  neck and back pain. An intervertebral disc is swollen or bulging  and is putting pressure on the nerve ro

What is left paracentral disc protrusion with impingement on neural foramina?

    This means that the spinal disc ("shock absorber" between the vertebrae) is protruding (bulging) on the left into the area where the peripheral spinal nerve leave
