Guest guest Posted September 6, 2004 Report Share Posted September 6, 2004 The pelvis is attached to the sacrum by ligaments. That was what I meant by loose ligaments. The sacral vertebrae become fused in most humans in their mid-20's (although in some people they don't fuse, and you can imagine the problems a person could have if some fused & others didn't!). Here's a pretty good summary: http://www.spineuniversity.com/public/spinesub.asp?id=89 One thing they say is: " The SI joint is a " viscoelastic joint " , meaning that its major movement comes from giving or stretching. The SI joint's main function appears to be providing shock absorption for the spine through stretching in various directions. The SI joint may also provide a " self-locking " mechanism that helps you to walk. The joint locks on one side as weight is transferred from one leg to the other. " And " One of the most common causes of problems at the SI joint is an injury. The injury can come from a direct fall on the buttocks, a motor vehicle accident, or even a blow to the side of your pelvis. The force from these injuries can strain the ligaments around the joint. Ligaments are the tough bands of connective tissue that hold joints together. Tearing of these ligaments can lead to too much motion in the joint. The excessive motion can eventually lead to wear and tear of the joint and pain from degenerative arthritis. Injuries can also cause direct injury of the articular cartilage lining the joint. This too, over time will lead to degenerative arthritis in the joint. " Ann Re: what I'm learning about the SI Joint Chris: I don't think it was loose ligaments at all in my pelvis. I think the SI joint just " popped out " from carrying the heavy laptop bag (w/ heavy textbooks too) on my shoulder -- standing waiting for the subway, etc. The loose ligaments were in my knee. My knee was most likely damaged from running with my left leg 1/2 " longer than my right -- which was due to the pelvis problem. The first couple of docs I saw said my cartilage was wearing away, but the " good " doc correctly diagnosed the problem. The only way to fix loose ligaments that I know of is prolotherapy. I don't think stretching & exercises will help much, except perhaps to unload some of the stresses on a particular area. As I understand it, once you are older than, say, 18 or 20, ligaments & tendons don't heal very well on their own. Old folks like us need some external stimulation (prolo) to promote healing. - Doug > > Other loose ligaments, was there anything else that you're aware of > that was causing the SI joint to go out on you?

Guest guest Posted September 7, 2004 Report Share Posted September 7, 2004 And as you know, falling is part of (in my case XC) skiing, at least when you're learning, and when I was learning (10 or so years ago), I got to where I could not only fall onto snow (which was, that year anyway, also concrete here (northern Sierra)), but was so used to it that when I went to learn rollerblading, and fell on real concrete, it was no big deal. But since I usually managed to land on one of the nice soft cushions God provided us with back there, and not smack on my tailbone, I'll bet that kind of torque really set my SI joint up for future unpeasantries.

Guest guest Posted October 8, 2004 Report Share Posted October 8, 2004 The sacroiliac joint. It's where your sacrum (the part of your spine above your tailbone -- in the sacrum the bones are usually fused together after age 26 or so, so it's like one bone) meets the pelvis. The connection between the sacrum and pelvis -- the SI joint itself -- is ligaments, and the bones have articular cartilage on them so they can slide against each other. The connective tissue (the joint parts -- the ligaments especially) is not supposed to be very mobile, but could be too mobile in one person or not enough in someone else. Sometimes after a pregnancy (during pregnancy, pretty much all pelvic connective tissue becomes more elastic), women remain too mobile in that joint. Since you have an SI joint on each side of the sacrum, the pelvis can get kind of out of place relative to the sacrum and cause you to have a " short leg " , and/or pain that would spread out to various places -- out into your lower back, your butt, down your legs, and with neighboring back muscles contracting in sympathy (or fear), even farther up your back. It's something definitely worth looking into if you're having a lot of lower body pain. Unfortunately, whereas SI causes used to be something doctors always looked at for lower back pain, their focus shifted several decades ago to intervertebral discs and they seem to have forgotten about the SI joint. I know it's hard to find doctors who will actually think about you and your particular problem. I think we've all had problems with that. Unfortunately, the only thing you can do is keep going from one doc to another until you find someone who will do what you need. Or if you live in or near a town that someone else here lives in, and they've found someone they can recommend. I hope you can find relief. You deserve better.

Guest guest Posted October 11, 2004 Report Share Posted October 11, 2004 thank you for your help ... i will read up on this and look into it ... the only test they did on my back was x-ray ... when they set up the MRI it was for my knee and i asked if they could do it of my whole body but they would not ? my back pain got better when i lost weight ... in 2 years time i lost over 80 pounds ... in my opinion if i had not lost that weight & if i had not done exercises for legs etc i would not be walking right now ... so anyone on here if yu are overweight with this problem i would suggest losing the weight for sure .... Ann I live in Ontario, Canada - near Toronto - a place called Oshawa but i do not think anyone on this site is near where i am ... 2 of the doctors i have seen are the best in this area ... thx ....
