What is the SI Joint?

The sacroiliac joint is the location in the body where the pelvis and the spine connect.

The term “sacroiliac” refers to the sacrum (the lower part of the spine) and the hip bone (commonly referred to as the ilium, which is technically the top part of the hip bone).

The joint is held together by ligaments and reinforced by muscle.

An injury to the SI joint typically involves an injury to the ligaments, which can cause the joint to move abnormally.

Muscles also play a key role in the function of the SI joint, so an important part of recovery for an SI joint injury involves strengthening these muscles to make sure they’re working optimally.

The exact shape of the SI joint can vary pretty widely from one individual to another, and there are also pretty significant differences in joint structure that depend on factors such as gender and age.

Because of this, what works for one person may not work for another. I have found that the SI joint is like a puzzle, and you must approach it intellectually in order to figure it out.

Here’s my very first video, showing you the location of the SI joint.  I’m still figuring out the whole Youtube thing so the quality might be somewhat lacking, but I hope you enjoy my first attempt!

And here are some posts I wrote to give you an introduction to the SI joint:

I hope this info helps to get you started as an introduction!
