“To do that because I know it's going to hurt. Those are tough ones because our heads weigh more than bowling balls. We're always encountering compression in our daily life. And some of those are some of the most stubborn cases of back pain. But I think in the big picture, you talked about freaking out over an MRI, right?”

“Yeah, I mean, I think the first thing I'll say is that we probably have been conditioned to think that it is all the same and it really isn't. You know, what we see in a sedentary population is generally going to be markedly different than what we encounter in our very athletic population, particularly those that utilize strength and conditioning on top of sports participation. So it's one thing to just be an Olympic lifter. It's another thing altogether to Olympic lift and then go play soccer or something like that. So I think we have to really understand our population norm for sure.”

“So, you know, it was done in 23 years ago. So, I think right now we are dealing with an epidemic of a lot of young athletes that always have stress fractures taking place. Every time I see an oblique strain on a professional baseball player, there's usually an old stress fracture, you know, listed on the radiology report that they just saw. So for a guy like you, it's a unique look because you have a wide variety of things that could be emerging. And certainly when you got your report read, they talked about absolutely everything that was on there.”

“We saw quite a bit more, and that was looking at a relatively unathletic population. And you look at yourself, like you've got a history in a wide variety of sports. You've tried just about everything. And when I saw yours, I started thinking more, there was actually studying the American Journal of Medicine that came out in 2000 that looked at elite Spanish athletes. And they're actually scoping especially for stress fractures. And what was interesting is they found 8% of Spanish athletes were affected and only 50% of them really demonstrated symptoms. So really you're looking at a scenario where one out of 20, one out of 25 actually had a stress fracture. They had no idea that was there. They saw it a lot in track and field throwers and rowers and gymnasts and weightlifters. But when I saw that study, I didn't buy it in an American population just because weightlifting is much more accepted here. We see way more early sports specialization here. We see more rotational sports, hockey, obviously lacrosse, baseball. Everything's just played at a much higher level. And I think that study was also.”

“It's very definition of a billion dollar question. I mean, just to speak to some of the things that you just kind of hinted at in terms of actual numbers, there was actually a landmark study in the New England Journal of Medicine that basically looked at a collection of asymptomatic splines. I believe there were 98 particular subjects. 52% of them had a disc bulge at one level, 27% had a protrusion, and 1% had an extrusion. So 82% of people had something on. And actually 38% of them had abnormalities at more than one level without having it in front of me. Your report was markedly more significant than that.”

“Yeah, there was one particular study, and I don't think it's at all reflective of a greater conspiracy theory in the radiology community. But if patients' pictures were actually shown to the radiologist before reading, they tended to read a little bit more intently. So I think it's like anything else. Radiology is a little bit like fine art. And they're ultimately trying to interpret what they see. And sometimes you can see a little bit more or a little bit less. And sometimes if you see something that's very slight, you might not relate it in a report, whereas other people might document absolutely everything.”

“You call your doctor, you go and get an MRI, and you get all the answers. And there may absolutely be a case for that in certain situations. And there may also be times where you get a whole bunch of false positives. They can wind up leading you to bark up the wrong tree. And that happens a lot with spines.”

“But I can certainly kind of draw maybe some conclusions from some of the things that you see relative to my sample size. So I always try to always illustrate that in our conversations. But the big picture I would say is that it has to be looked at as a piece of the diagnostic puzzle. So really no diagnostic imaging is appropriate without an accompanying physical exam, a full kind of case history as you go through a variety of things. Because as we kind of alluded to in that initial email, it's like there's a lot of other things that can impact it. And what's really fascinating, maybe this is the place where it gets intriguing for people is there's actually an article that came out in the Lancet in 2009, an exact quote from it that said lumbar imaging for low back pain without indications of serious underlying conditions does not improve clinical outcomes. Clinicians should refrain from routine immediate lumbar imaging in patients with acute or subacute low back pain and without features suggesting a serious underlying condition. So we've always been taught the second something gets hurt.”

“Your experience is not at all, I hate to say it, unique. I think it's very much something that happens every day. And let me preface this by saying I'm not a radiologist. I'm not an orthopedic surgeon. I'm not a doctor in any capacity. I'm a strength conditioning coach. So I kind of found this world by accident. I do happen to look at a couple thousand radiology reports every year. It's something that kind of happened by accident just because you started to try to work backwards from the conditions that we were seeing people who are having pain in various points in their body. And we wanted to understand why. This is not to take away from radiologists or doctors at all because it's an incredibly specialized approach and it's a huge part of the diagnostic puzzle. But the thing that I would say that's interesting, first off is we'll have people that'll walk in with their films and I'll say, listen, I'm not reading those for you. People go to school for a decade to understand how to do that.”

“Correct. And then what we have is we have a lot of people that have probably done a little bit of both and created adaptations in both directions. Maybe it's the plumber who goes out and then plays in a wreck basketball league four nights a week or something like that. So everyone presents, I think, with a different history of activity and symptoms and either successful or failed treatments that may have intervened in one way or another. And it often leaves us just in this situation where you can't just look at these all the same.”

“Case being different, yeah. Somewhat different. You know, speaking in a really, really broad strokes in an athletic population, we tend to see much more extension-based low back pain. So what we're going to see in a tennis player or a baseball player or soccer player is probably markedly different than what we're going to see as someone who sat at a computer for 30 years or a roof or a plumber, a floor who spent a lot of time inflection.”

“I think back pain is fascinating. Obviously, it's an all encompassing diagnosis. It covers a lot of different things that impacts a lot of different people. What's particularly fascinating about it is it's very different. If you're a nine-year-old kid and you fall off the playground, you break your form, you throw in a cast, he heals up, you're good to go. There's a much more significant level of chronicity that happens with the back pain that we see in the general population. And I think what's to my email's point, the term non-homogenous was when I actually stole from Dr. Stuart McGill, who's great in this. And he's talked about how the medical system may not actually be well designed to handle anonymous condition like meaning widely varied.”

“I do. I think it was 415 for 25, and I made the mistake of doing it Thanksgiving morning and absolutely ruined the holiday. I think I had a headache for about four days. Definitely one of my more ignorant moments in my youth, all in the quest of science, though, right? All in the quest of”

“I pulled 660 at a body weight of 181, a little bit lighter at a body weight of 165. So I've lifted my fair share of heavy stuff without really a well-targeted long-term goal with it in mind.”
