How does the SI joint relate to other causes of low back pain? (Coordinated Health TV: Low Back Pain Part 1)

Hi, all.

As many of you know, I’m currently in the process of trying to come up with some better visual aides for you…  which might possibly end up including videos…?  (Gulp).

As part of this process, I’ve been doing a little bit of research to try to figure out what’s already out there, and how other people have tried to address these topics.

Yesterday I stumbled across this really great informative video series from Coordinated Health (they are a physician-owned hospital network based in Pennsylvania).

I was really blown away by their series, and I think it’s totally worth watching.  I’ve actually *never* seen such a comprehensive resource on lower back pain that manages to address SI joint dysfunction so thoroughly, and also explain how it fits into the larger picture of all of the possible causes of low back pain.

Below, I am including Part 1 of this series.  Its title is “Anatomy of Muscle, Facet Joint, & Sacroiliac Joint Injuries.”

This video (and the rest of the series) will be really helpful to watch if you are struggling to understand the SI joint, or its relation to the rest of the lower back and pelvis.  It should also really help clarify for you some of the other potential causes of pain your doctor may be trying to rule out, and the rationale for some of the testing he or she orders.

As the video explains, there are many possible causes of low back pain, and it isn’t always obvious at first what the problem will be.  Additionally, you may have pain coming from more than one area, so it’s important that your doctor consider all of the different possible factors.

Again, I just really love this video because it treats the SI joint as a major consideration, whereas I (like most of my readers) have come across doctors who aren’t even aware that it can cause pain at all.  So it’s very vindicating.


I also thought the host did a really amazing job of explaining the SI joint, and it will definitely influence the way I attempt to talk about it in the future.  So I wanted to note a few parts that I thought would be the most relevant to readers of this blog:

Muscles (at the 4:05 mark): explains how the muscles that connect the spine to the hip bone can cause a lot of pain when they tighten up, giving the person the sense that their spine is “crooked” (because it’s being pulled on unevenly).


This is something I’ve addressed before:

The SI Joint (and its jagged surfaces) (at the 6:40 mark)

He does a great job of explaining how the surface of the ilium and sacrum fit together like the “tongue and groove” in furniture.  This is something I haven’t addressed directly, because I wasn’t quite sure how to explain it.  However, his drawings at the 8-minute mark really do an amazing job of showing what happens when the joint surfaces aren’t lined up correctly.



So, that’s all for now!

As a patient, I have always found that I felt more comfortable and in-control the more I felt that I understood.

So when I share resources like this with you, it isn’t necessarily because I think you need to understand every single word.  It’s more to give you a sense of what information is out there, and that, even if you don’t need a particular resource right now, it will be there if and when you need it.

You can find all of the videos on the Coordinated Health TV Youtube channel.  To help you reference them quickly, I’ve also saved them into a playlist on my Sunlight in Winter channel.  

So if you want to know more about the possible causes of lower back pain, and how the SI joint fits in, I would definitely check this series out!  As always, feel free to drop me a line with any questions!
