Sometimes discs may bulge -- move out of place -- and put pressure on nerves that exit your spine. Symptoms are specific to the level of the bulge. An L4/5 bulging disc puts pressure on your L5 nerve -- one of the most common levels where this condition occurs.

Unlike a disc that is bulging, a herniated disc occurs when tears in or ruptures of the outside of the annulus allow some of the soft material nucleus pulposus to exit the disc. Pain and other symptoms related to a herniated disc may occur should the escaped nucleus pulposus comes into contact with a spinal nerve root.

"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 also resists large tensile and compressive strains as the disc undergoes 6 degree of freedom motion. The cartilaginous endplate is an interface tissue connecting the disc to the adjacent vertebral bodies, and functions to distribute stresses between the disc and vertebrae and to act as a gateway for nutritional transport in the ...

The difference between a bulge and a herniation is that, in a bulge, a larger part of the disc displaces beyond its normal boundaries. In a disc herniation, there is a less than 25% focal displacement of the disc beyond its normal boundaries. In a disc bulge, there is a greater than or equal to 25% generalized displacement of the disc (Figure 4 ...

Annular fissures are a degenerative deficiency of one or more layers that make up the annulus fibrosus of the intervertebral disc . Many authors prefer the term annular fissure over annular tear, as the latter seems to imply acute injury 1,2.

Conservative treatment that may include a combination of nerve decompression and noninvasive pain management techniques is used to treat small annular tears with disc bulges at L4 or L5, as stated by Laser Spine Institute. The appropriate treatment for an annular tear depends largely on the cause and severity of the damaged disc.
