The sacroiliac joint (Sacroiliac Joint) connects the pelvis and the spine and belongs to the planar joints. A comparatively high static pressure can cause blockage, just as in the spine, and impair its function.
The cause is usually a wrong movement, such as during lifting a heavy object or when overlooking a step on the stairs. The ensuing pain is located in the lower back, mostly on one side, and can radiate into the leg. In cases of rheumatic disease, the Sacroiliac Joint can also become inflamed. Degenerative diseases - symptoms of wear and tear - are quite rare.
