Bulging disc

What is a bulging disc?

A bulging disc extends beyond the edges of the vertebrae above and below it, but the outer ring remains intact. Nothing has escaped through a tear.

The bulge is typically broad, involving a substantial portion of the disc's circumference, rather than the focal protrusion seen in a herniation.

It may cause no symptoms at all, or it may narrow the space around a nerve root enough to produce pain and neurological findings.

Radiology reports use varying terminology, and the same finding may be described differently by different readers, which occasionally becomes an issue in itself.

It is among the most frequently reported findings on spinal MRI and among the most frequently contested in litigation.

Why is it harder to prove?

Several features make it a weaker starting point than a herniation.

• Bulges are common in people with no symptoms at all
• They develop gradually with normal age related change
• The finding alone does not establish when it occurred
• It is a less dramatic imaging finding than a herniation
• Defense experts characterize it as degenerative almost as a matter of routine

How is a crash related bulge established?

Through correlation rather than through the image alone. What matters is whether the clinical findings match the level imaged and whether symptoms began at the time of the crash.

The absence of any prior complaint about that region carries weight, particularly where medical records covering earlier years show no treatment for it.

Where prior imaging exists, direct comparison is the strongest evidence available, since it shows whether the finding is new or unchanged.

What else strengthens the claim?

Nerve testing. Where a bulge produces confirmed radiculopathy on electrodiagnostic study, the finding moves from anatomical to functional.

That distinction matters considerably, because a bulge that is affecting nerve function is doing something rather than merely existing.

Consistent treatment without a gap also matters more here than for a stronger imaging finding, since the record is carrying more of the weight.

A physician's opinion connecting the mechanism of the crash to the finding carries the argument where the imaging alone does not.

Common questions

Is a bulging disc less serious than a herniation?

Anatomically it is a lesser finding, though symptoms depend on whether a nerve is affected rather than on the label alone.

The defense says my bulge is age related. How is that answered?

Through timing of symptom onset, correlation with clinical findings, absence of prior complaints and comparison with any earlier imaging.

Can a bulging disc meet the verbal threshold?

It can where supported by objective findings such as confirmed radiculopathy and a permanency opinion, though it is harder than with a herniation.
