The sacroiliac joints are comprised of the triangular sacrum (at the base of the spine) and the right and left ilia, which together form the pelvis. The SI joints lie under the “dimples” at the base of the low back. They are held together by strong ligaments and typically have little motion, although they can become “stuck” or fixated, or at times hypermobile (too loose) such as during pregnancy. SI joint pain can mimic other types of low back conditions. Your chiropractor will perform various orthopedic and other tests to determine if you are suffering from SI joint syndrome.
