"Annular bulging" refers to a protrusion from a spinal disc that is still contained by the annulus, connective fibers that give the spinal discs strength. When these fibers are torn or compromised, the condition is known as a herniated disc. Annular bulging is treated with anti-inflammatory medication and usually heals within several weeks.


The annulus fibrosus is the outer cartilage ring of the disc complex. The disc complex is made up of the annulus fibrosus and the nucleus pulposus. The nucleus pulposus is the jelly like center of the disc complex. So, the annulus, which is the outer ring, holds in the pulposus. It is very common for the annulus to bulge. It is designed to do so.


L3-L4: Mild diffuse disc bulge and facet arthropathy. No central canal stenosis. There is mild right and mild-to-moderate left neural foraminal stenosis. L4-L5: Diffuse disc bulge with a small central disc protrusion. There is buckling of the ligamentum flavum and minimal facet arthropathy. No central canal stenosis.


--Diffuse disc bulge at L5-S1 level with central disc protrusion causing moderate compression on thecal sac and both intervertebral foramina. no significant nerve root compression. --Mild Annular disc bulges at L3-4 and L4-5 levels with mild compression on thecal sac. no nerve root compression.


At L5/S1 there is a mild, broad based annular disc bulge. On the right side, there is small focal protrusion of disc material into the right lateral recess which must be compromising the transiting right L5 nerve root. Moderate facet joint hypertrophy causes mild narrowing of the central canal.


I believe you may be confusing the word "anterior" with the word "annular." You can have an annular bulge located in a posterior position. The annular bulge refers to a bulge in the [B]annulus fibrosus[/B] which is a component of the spinal disc.


Hello, Thanks for the query. "Your MRI is necessarily normal, except for the annular disc bulge at L4-5 level." Fortunately the disc is not causing any pressure over the nerves or cord. Nevertheless it has a chance of doing that soon if you dont take adequate precautions at this stage itself.


Best Answer: Jennifer, I am not sure what you are asking here. I will give you an interpretation of this information. The L4-5 mild annular tear is related to the disc. The disc is made up of layers much like that of a radial tire with each layer or ply going in another direction to withstand a specific ...


Bulging discs are listed under the category of impairments known as Musculoskeletal System – Medical Listing 1.04. The following criteria have been established indicative of the inability to engage in any substantial gainful activity, i.e., if one has a diagnosis of a disorder of the spine (bulging discs) and one of the following, a finding of disabled under the Social Security Act is warranted:


Disc bulge is a projection into spinal canal or foramina of soft gelatinous nucleus pulposus with intact fibrous annulus covering of the disc. Advertisement Lumbar foramina is a lateral bony tunnel meant to pass the spinal nerve and lumbar spinal canal accommodates lower end of spinal cord and quada equina (see Figure 2).
