What is a Sacroiliac Joint and why does it cause Pain? Shown and explained with Color X-Ray Images

The Sacroiliac Joint (SI Joint) can be a nagging source of chronic back, hip and buttock pain. This Joint is quite different from other Joints in the human body such as the hip, knee, or ankle joints. Unlike these joints which provide a significant amount of mobility, the Sacroiliac Joint normally moves only a fraction of an inch.

Lets take a look at the general location of the SI Joint. The Image below is a Color X-Ray which shows the location of the Sacroiliac Joints (green arrows). The Sacroiliac Joint is the Joint located between the Tailbone (Sacrum) and parts of the Hip Bone (Pelvis). This Image is Interactive. It contains Interactive Image Tags which display text as the mouse cursor moves over it. Each tag explains part of the Anatomy.

There are many potential causes of inflammation and pain of the Sacroiliac Joint. Some examples are: Patients with unequal leg length; previous pregnancy; history of Lumbar Fusion Surgery (low back fusion); Rheumatoid Arthritis; prior trauma to the Pelvis.

The next Color X-Ray Image shows Normal and Degenerated Sacroiliac Joints. The Normal SI Joints are shown in the left, Degenerated Joints on the right. The Degenerated Joints are narrowed by bone spurs causing Arthritis. It is important to know that inflamed and painful Sacroiliac Joints can look "normal" on an X-Ray. Only the more advanced stages of Arthritis of the Sacroiliac Joint are visible on X-Rays. Cat Scans can show more detail and can pick up Sacroiliac Joint Degeneration earlier. A Nuclear Bone Scan can show severe inflammation of a Sacroiliac Joint. This next Image is also Interactive.

Treatments for chronic Sacroiliac Joint pain range from Chiropractic Pain Medications, Physical Therapy (PT) and Chiropractic Adjustments to injections and in some cases even surgery. The option of Surgery should be reserved for patients who have failed all other more conservative types of medial care and have a limited quality of life due to pain from Sacroiliac Joint Disease. The Color X-Ray Image below shows and explains a Minimally Invasive Sacroiliac Joint Fusion Surgery.
