The SI joint is mainly held together by bands of connective tissue known as ligaments.
These ligaments hold the sacrum (base of the spine) and the ilia (hip bones) together to make up the two sacroiliac joints.
Here are some diagrams which give you a general view of what the ligaments look like:
An injury to the SI joint will generally involve an injury to one or more of these ligaments.
Like all ligaments in the body, when one of the SI joint ligaments is injured, it can stretch out and become looser than normal. It can also be inflamed, which can cause additional pain.
Unfortunately, our bodies are not great at repairing ligaments. Once a ligament becomes stretched out, it does not always regain its shape.
This is why SI joint injuries are so persistent and difficult to heal. Our bodies were counting on those ligaments to hold our SI joints in place, and now they are no longer doing their job.
Even if your ligaments are stretched out, however, you can still heal:
I had to strengthen my muscles, so my body didn’t rely on my ligaments as much.
I learned to stop doing things that aggravated my ligaments, which allowed them to heal faster.
Finally, I ended up realizing that chiropractic adjustments were putting too much force on my SI joint ligaments. Even though the adjustments were technically putting my joints “into place,” at a microscopic level, they were also re-spraining the ligaments each time, making it harder for the adjustment to actually stay in place.
I got a lot better once I switched over to using the Muscle Energy Technique to realign my own joints.
There are other things that work for some people, as well.
- SI joint belts and taping are two ways to add external support to the area
- Prolotherapy is a form of therapeutic injection that has been shown to speed ligament healing. It is not a magic bullet, but it does seem to help some people.
- Surgery: a surgeon uses screws to attach the bones of the SI joint together. (The screws end up doing the job the ligaments once did). Surgery is a very big undertaking that has risks, and some patients do not feel better afterwards, so it is something that requires a lot of research and forethought.
I’ll be talking about all of these options in more detail in the future. Stay tuned!
Been a yr with SI joint pain (left side) Did 3 months of Chiropraric with 3 adjustments a week. Did physical therapy prior. Haven’t tried aquatic training. Flare ups have been sidelining me here and there. Makes me feel like this will never end. Thank you for giving us hope.

You’re welcome, Benjamin! I wish you all the luck in finding a way forward. Sometimes you just don’t know when things are going to fall into place– but they can, and do. Personally I had to go through 8 different physical therapists before finding someone who could really help me– but that’s what got me where I am today! Keep searching!
