Sacroiliitis (say-kroe-il-e-I-tus) is a medical condition caused by any inflammation within one, or both, of the sacroiliac joints. Sacroiliitis is a feature of spondyloarthropathies, such as axial spondyloarthritis (including ankylosing spondylitis), psoriatic arthritis, reactive arthritis or arthritis related to inflammatory bowel diseases, including ulcerative colitis or Crohn's disease. It is also the most common presentation of arthritis from brucellosis.
Sacroiliitis is a condition caused by inflammation within the sacroiliac joint. This joint is located where the base of the spine, known as the sacrum, and the pelvis, known as the ilium, intersect. "Itis" is a latin term denoting inflammation.
Since sacroiliitis can describe any type of inflammation found within the sacroiliac joint, there can be a number of issues that cause it. These include:
People suffering from sacroiliitis can often experience symptoms in a number of different ways, however it is commonly related to the amount of pressure that is put onto the sacroiliac joint. Sacroiliitis pain is typically axial, meaning that the location of the condition is also where the pain is occurring. Symptoms commonly include prolonged, inflammatory pain in the lower back region, hips or buttocks.
However, in more severe cases, pain can become more radicular and manifest itself in seemingly unrelated areas of the body including the legs, groin and feet.
Symptoms are typically aggravated by:
Sacroiliitis can be somewhat difficult to diagnose because the symptoms it manifests can also be caused by other, more common, conditions. If a physician suspects sacroiliitis, they will typically begin their diagnosis by performing a physical exam. Since the condition is axial, they can often pinpoint the affected joint by putting pressure on different places within the legs, hips, spine and buttocks. They may also ask a patient to perform some stretches that will put gentle stress on the sacroiliac joints.
