Sacroiliac Joint Dysfunction
The sacroiliac joints (SIJ) are located both sides of the base of the spine and are the joints connecting the sacrum (base of the spine) to the pelvis. SIJ dysfunction is the term used to describe a number of SIJ injuries that affect the function of the SIJ. These can include traumatic, biomechanical, hormonal or inflammatory or degenerative joint disease. These injuries may cause hypomobility (less movement) or hypermobility (more movement) of the SIJ. This altered function can cause further problems with the surrounding muscles and ligaments resulting in low back pain, buttock pain, and even pain traveling down into one or both groin regions, hips and/or thighs.
