Have you seen a doctor about this. I did a search and could not find anything. If you did go to the doctor then I am really ticked off. He/she should have spent the time to tell you in laymans terms exactly what it is you have. If it were me (and I have done this on mumorus occasions) call back and demand a diagnosis and find out with the heck it is that you have. The ilium, if I am not mistaken is somewhere between you back bone and you hip. I did read somewhere that is may have something to do with arthritis.

ilium upslip is a type of sacroiliac joint dysfunction. The ilium are the large pelvic bones that form the hip joint with the the top of the femur (thigh bone) you were right MsCarrie. The bottom of your spine sits on the top of your sacrum and both the Illa are attached to either side of the sacrum, the whole lot (sacrum and two Illa) form the entire pelvis. The two joints between the sacrum and ilia are called the sacroiliac joints, and there is a small degree of movement in these joints. Ilium upslip is when is when the sacrum slips down on the ilium so the the two bones are not sitting snugly together like they should be.

there are many other types of sacroiliac joint dysfunction many researchers think that they are quite common and can be the cause of back pain chiro's osteopaths and physical therapist often diagnose and treat these disorders how ever doctors generally do not recognise them and some refute their existence.

here is a picture if all i did was confuse people

It hurts to sit down for a long time, or walk for a long time, as well as bend down using my back, not my knees.
I was dropped on my back on concrete 2 months ago. The pain has gotten worse since, and I saw a doctor about it. He told me the amount of radiation that had to go through my uterus/ovaries could be dangerous in an X-ray, but he checked an x-ray I had gotten of my lower back from getting it by a car years ago. He told me there are two bones that connect to the sacrum that are supposed to sit comfortably, but are overlapping. I should ask him for more details and a diagnosis too. I think I just might have an ilium up/downslip.

Hi there

Ilium upslip means that the pelvis and the sacrum are misaligned. It is a term that was used about 40 or so years ago.
In present terminology it would be called; 'Sacroiliac condition. It is easy to overcome by massaging the bony knobs on the back of the hip for 30 seconds at a time about a dozen times a day for a week, than sit back to front on a dining chair, spread your arms like an aeroplane and rotate your body quickly from left to right about 5 times.
The sacrum is a triangular shaped bone that is actually formed by the fusion of several vertebrae during development. The sacroiliac (SI) joint sits between the sacrum and the iliac bone (thus the name “sacroiliac” joint). You can see these joints from the outside as two small dimples on each side of the lower back at the belt line. The SI joint is one of the larger joints in the body. The surface of the joint is wavy and fits together similar to the way Legos® fit together. only a small amount of motion occurs in the SI joint and is a combination of sliding, tilting and rotation.
The most the joint moves in sliding is probably only about 3 or 4 millimeters, and may tilt and rotate two or three degrees.
The SI joint is held together by several large, very strong ligaments . The strongest ligaments are in the back of the joint outside of the pelvis. Because the pelvis is a ring, these ligaments work somewhat like the hoops that hold a barrel together. If these ligaments are torn, the pelvis can become unstable. This sometimes happens when a fracture of the pelvis occurs and the ligaments are damaged. Generally, these ligaments are so strong that they are not completely torn with the usual injury to the SI joint.

I hope that has shed some light on the subject and supplied a way of overcoming it.
Again, Vitamin C is valuable for the repairwork if any of the ligaments are damaged. Possibly between 2 and 3000 mg a day.

Good luck

I have suffered with this problem for 5 years, although it has just been diagnosed. My pelvis is so unstable that my hip flexor tendon shredded over time and had to be repraired. In the meantime, I have become almost diabled with pain, I'm only 48 and usually a very active person. The exercises my PT has given me to correct the problem over time makes the pain worse, even the slightest exercise throws my pelvis off again and my muscles go into spasm. My SI joint is so painful it can barely be touched. The pain goes all the way down my leg and ends with a burning under my foot, which is constant. Its so bad I've even considered suicide. My PT can take my pain level from an 8 to a 2 in one session, but then it goes back to an 7 within a few hours. I'm not sure you can be more desperate than this, or feel more helpless because there seems to be no solution.
