Creating my own visual aides! (Some basic views of the SI joint).

Hi everyone!

The more and more I’ve been working on this blog, the more ideas have come to me for better ways to explain things.

When I first limped into my chiropractor’s office with my SI joint stuck all those years ago, I really appreciated the explanations he gave me using an anatomical model, so that I had a better understanding of what was happening to me.

However, it took me a long time, and a LOT of explanations to really wrap my mind around the concept what exactly this joint is.  (I would have gone to his office every day if I could, just to hear it again.  I knew that educating myself as much as possible on this joint was going to be my way out of this situation).

Fast-forward to all these years later, and I decided to go ahead and buy this handy-dandy model of the pelvis for myself, so that I could come up with better illustrations for you guys.   (And hopefully soon, video tutorials!).

In my opinion, you shouldn’t have to go all the way into someone’s office, and pay them to treat you, just to get a decent explanation of what is even going on.  Hopefully, that’s where my blog can come in.


In this post, we are just going to start out with some simple views to help define the sacroiliac joint.

Anterior view

Let’s start by looking at the joint from the front (the scientific term for this is the anterior view).

The term sacroiliac joint refers to the meeting of the sacrum and the ilium.

So, where is the sacrum?  It’s right here: it forms the base of the spine, but is also, as you can see, very much part of the pelvis:


And here is the ilium, or the part of your hip bone that connects to the sacrum:


Put them together and what have you got?

The connection of the sacrum + the ilium = the sacroiliac joint:


As you can see, my pencil is pointing right into the space between the sacrum and the ilium.  That space is the joint.

And here is a close-up view of the two SI joints:


Posterior view

Now, let’s look at the exact same thing from the back (or, in other words, the posterior view):

Here is the sacrum (the base of the spine):


And here is the ilium (the part of the hip bone that connects to the sacrum):


Put them together and you have:

The sacroiliac joint (view from the back):


This whole space between the sacrum and the ilium is the SI joint:


And here is a close-up of the SI joint from the back:



Okay, so these were just some simple views to help get you started.

I truly believe that knowledge is power, so if you’re taking steps to educate yourself on the mechanics of this joint (and reading awesome blog posts like mine!), you should feel confident that you’re taking steps to improve your situation.

What the answer might be is different from person to person, but you have options, and there are reasons to be hopeful.


I’m really curious to hear what types of explanations (and now, illustrations) work best for people, so please feel free to drop me a line!

Also, I haven’t forgotten about your requests for more info on my exercises.  I am working out the kinks, but I promise it is coming!
