They can try.

They do try.

And if you have an old MRI, a chiropractor note from five years ago, or one chart entry that says "chronic low back pain," the insurance side will act like they just found the smoking gun.

That does not mean they automatically win.

A bad back before the accident does not let them off the hook

Here's the core idea: Wyoming law does not require you to be in mint condition before you got hurt.

A person with some wear and tear, a prior disc issue, or an old back strain can still have a valid injury claim if a new incident made that condition materially worse.

That is the whole fight in a lot of serious back cases.

Not "were you ever hurt before?"

Not "did an MRI already show degeneration?"

The real question is whether this incident aggravated, accelerated, or lit up a condition that had been manageable before.

That matters because insurers love to blur the line between:

• a pre-existing condition that existed in the background, and
• a new event that turned that background problem into real disability, real pain, surgery, missed work, or permanent restrictions

Those are not the same thing.

The old MRI is not magic

This is where people get rattled.

The adjuster says the MRI already showed bulges, stenosis, degeneration, annular tears, spondylosis, whatever. They say your back was "already bad."

In Wyoming, that kind of imaging is common as dirt once you get into your 30s, 40s, and 50s, especially if you've done physical work. Commercial fishing, oilfield labor around Casper or Gillette, trona work near Green River, ranch work, construction along the Front Range corridor, hauling freight when I-80 is trying to blow you into Nebraska - all of that puts miles on a spine.

A radiology report does not tell the whole story.

Plenty of people have ugly-looking MRIs and still work full shifts.

Then one bad lift, one fall on a wet deck, one violent jolt, one twist while bracing in rough water, and suddenly they cannot sit, cannot sleep, cannot lift a coil of rope, cannot climb, cannot rotate, cannot work.

That change is the point.

If you were functioning before and not functioning after, the insurer's "well your MRI wasn't perfect" line starts looking a lot weaker.

This is the eggshell plaintiff rule, even if nobody uses that phrase on the phone

Most regular people never hear the term until their case gets ugly.

The eggshell plaintiff rule basically means the wrongdoer takes the injured person as they find them.

So if your spine was more vulnerable than somebody else's, that does not give the defense a discount.

They do not get to say, "Well, a healthier person might not have been hurt this badly, so we only owe for part of it."

If the incident set off a much worse injury because your back was already susceptible, that vulnerability does not erase responsibility.

Now, the defense will still argue about how much of your condition was already there.

That's the money fight.

But the existence of a vulnerable back is not some automatic shield for them.

What insurers do with your medical history

They don't read your records like a doctor trying to treat you.

They read them like a weapon.

That means they hunt for phrases like:

"history of back pain"

"degenerative changes"

"chronic pain syndrome"

"prior lumbar complaints"

"similar symptoms"

"maximum medical improvement"

"pre-existing"

Then they build a story that everything happening now is just the natural progression of old problems.

This is where a lot of injured workers and accident victims get blindsided. They think the issue is whether they've ever had back pain before.

That is too crude.

In adult life, especially in hard-body jobs, a lot of people have had back pain before.

The sharper questions are:

What actually matters more than the old records

First, what were you able to do before this happened?

Were you working full duty offshore?

Lifting gear?

Sleeping normally?

Driving long stretches?

Climbing ladders or stairs without lighting up your leg?

If you were getting through life and work, that matters.

Second, what changed right after the incident?

Did pain spike immediately?

Did symptoms move into the leg?

Did numbness start?

Did you go from occasional soreness to constant pain?

Did you suddenly need injections, surgery, stronger meds, or restrictions?

Third, do the records after the incident tell a consistent story?

Because consistency is what keeps the insurer from turning your chart against you.

If the early records say one thing, the later records say another, and your symptoms are described sloppily, the defense will jam a crowbar right into that gap.

Wyoming juries understand worn-out bodies better than insurers think

This state is full of people who work through pain.

That is especially true in places built around extraction, transport, and weather. In Natrona County, Campbell County, Sweetwater County, and along the I-80 and I-25 corridors, nobody is shocked to hear that a worker had some prior back trouble and kept showing up anyway.

That cuts both ways.

Jurors are not impressed by whining over minor aches.

But they also understand the difference between a person who had manageable pain and a person whose life got blown apart after one event.

If you had an old lumbar MRI from years back and were still doing your job, then after the incident you could not return to deck work, heavy lifting, bending, or even basic movement without severe pain, that before-and-after picture is powerful.

Much more powerful than the insurer wants you to believe.

The dirty trick is making "pre-existing" sound like "not caused by this"

Those phrases are not interchangeable.

A condition can be pre-existing and still be seriously aggravated by a new incident.

That is what people miss when the claims side starts talking fast.

They want you to hear "pre-existing" and give up.

They want you to think an old MRI means the case is dead.

It doesn't.

What kills these cases is usually not the existence of prior back problems.

It's weak proof of the change.

If your records, work history, and symptom timeline show that you were functioning before and disabled after, the insurer's favorite talking point starts to crack.

And if the boat owner, carrier, or defense doctor is pretending your medical history means you were already doomed anyway, that's not medicine.

That's a blame-shifting strategy dressed up in medical language.
