99% of adults over 40 have shoulder "abnormalities" on an MRI, study finds

You call it "abnormality", I call it evolution. We are not the same.

How many generations of constant bent over posture staring at a device before that's just built into the species?
plufz•42m ago
Im not sure people with bad posture get more offspring than others. :)
dylan604•30m ago
The pickins are getting slim though. I don't know anyone in their 20s that doesn't sit hunched over staring at a screen for a large portion of their day while stipulating I don't know any where near all 20 somethings. Just one person's observations

laughing_man•25m ago
More likely someone who's been in a coma for the last ten years.
elzbardico•5m ago
I would strongly bet against gym rats not having some should abnormality. If anything, I'd expect them to have more issues with their tendons and ligaments.

Even though they never have any neck pain, many shoulder issues are actually caused by pinched nerves in the cervical spine.

"1% of adults over 40 have abnormally normal shoulders"
Insanity•35m ago
That's actually what the article points out. But I do think the language of normal vs abnormal obfuscates some of the intent. It's a 'deviation from healthy baseline' that they're talking about, and there are multiple such deviations in the grouped 'anomalies'.

From the article:

The language in particular should change given that “abnormalities” are ubiquitous—thus normal—and shouldn’t be described in terms that indicate a need for repair, like “tear.”

brandall10•31m ago
Right, it's clearly aging related deterioration. It's like saying facial wrinkles are an abnormality.
cies•29m ago
Dunno man. When enough people overweight, 1-2 alcoholic drink become healthy (alcohol is a blood thinner): this happened, but as we know now it's not true.
Qem•24m ago
> alcohol is a blood thinner

Source?

hinkley•15m ago
Alcohol reduces clotting factors in the blood. This is known.

Doctors mostly tell you not to drink because it’ll fuck with the anesthesia math and bad anesthesia doses can kill you just as dead as a surgical mistake and probably moreso. But it’ll also make you bleed more.

If you need courage to show up to surgery they’ll give you a prescription for a single dose of a benzo. Which is better than liquid courage anyway.

diydsp•27m ago
Yes in one sense, but it also points to the insufficency of "normalness". See also: The Average Soldier.
hinkley•17m ago
There’s a famous case study in design about the Average Pilot - they were making airplanes than nobody could fly well because nobody was average enough in all physical dimensions to be comfortable in the aircraft. They had to design for ranges that the equipment could adjust through.

Even then when I was a kid I knew a guy who wanted to join the air force and he had a growth spurt that made him too tall.

pinkmuffinere•4m ago
Dude I know exactly who you're talking about, that guy without a unique face! Weird as hell that he's the only one...
mghackerlady•15m ago
Ok, in that case it's safe to say that the normal is highly variant but generally follows a pattern. People generally have a nose in the center of their face so that'd be normal, but one on the forehead would be abnormal unless everyone suddenly also had forehead noses
dijit•14m ago
I think the conclusion they're eluding to in the article is that: "if MRI says 99% of people have abnormalities, MRI is not trustworthy".

Most of my shoulder issues are sleep related since I sleep on my side. Getting a body pillow system, was costly but kinda worth it. Helps with shoulder and GERD. Only issue is that it's kinda warm and I like to sleep cool.
ASalazarMX•36m ago
> was costly but kinda worth it

This doesn't inspire confidence, but I guess any improvement that mitigates pain is nice.

But seriously, the article addressesd that

> The authors argue that the findings suggest clinicians should rethink MRI findings, changing not just how they’re used, but also how they’re explained to patients. The language in particular should change given that “abnormalities” are ubiquitous—thus normal—and shouldn’t be described in terms that indicate a need for repair, like “tear.”

mgiampapa•31m ago
The issue with those inclined pillows with the arm hole in them is that they can be a really hard angle for a side sleeper to be at. It makes my back and hips hurt way worse than my shoulder.
dralley•25m ago
Any recommendations? I have GERD and generally sleep on my back, which helps but isn't perfect.
cactusplant7374•4m ago
Cervical radiculopathy can cause shoulder pain. I have experienced this quite a bit and it's probably also because of my sleeping style. I wouldn't get an MRI unless I was planning to have surgery.

I have three kids and they've messed up my dominant schoulder (left).
p00dles•30m ago
From walking around holding them with your left arm when they were babies, or from something else?
Glyptodon•32m ago
I don't know what causes it, but even without major issues I think a lot of people continually loose range of motion in the shoulder as they age. So this doesn't surprise me.
baxtr•22m ago
What about the other 1%? I feel for them.
TacticalCoder•20m ago
Any arm or just the arm in which they got a mRNA injection that wasn't a vaccine (at least not before the official definition of what a vaccine is got modified). I'm asking because I do happen to have pain in the shoulder/upper arm in which I got the (supposedly) anti-Covid jab.
laurex•14m ago
Given that most commenters do not seem to have read the article perhaps the headline could be more explicit about 'MRIs find "abnormalities" but they seem to have no relationship to actual health problems"
nickjj•9m ago
Do they define if this relates to anything noticeable in your day to day?

For example, I can put my right hand above my shoulder and left hand near my lower back and easily connect both hands behind my back with fully interlocked fingers by converging in the middle. They reach to the other hand's palm.

But I can only barely touch my fingers with both hands if I switch it up so my left hand is up top.

I have no pain or day to day mobility issues but something is lopsided. Is that what they consider abnormal?
