Dysfunction of the sacroiliac joint is pain in the joint that
connects the illium and sacral bones of the pelvis. The sacroiliac
joint is located next to the spine, above the tailbone, and absorbs the
shock of the motions from the upper body on the lower body.
Sacroiliac joint dysfunction can be caused by traumatic
accidents, but is most often caused by a change or abnormality in
movement in the area – either too much movement, or too little.
Abnormal changes in the motion of the sacroiliac joint, a strong, weight-bearing joint, can cause a patient to feel pain in the lower back, leg, hip, groin, and buttocks. Numbness or tingling in these areas can also be a symptom in some cases, but is more rare. If a patient with sacroiliac joint dysfunction feels pain in their lower back or hip, it is likely a result of hypermobility, or too much movement. Too little movement (hypomobility), however, usually causes a patient to feel pain on one side of their buttocks or low back, and occasionally down one leg.
It is difficult to correctly diagnose a patient’s pain as sacroiliac joint dysfunction because many of the symptoms of the condition are similar to those of other conditions; if a patient feels shooting pain down one of their legs, it may feel similar to sciatica pain. Many of the symptoms of sacroiliac joint dysfunction are similar to facet syndromes and lumbar disc herniations as well. A medical practitioner can help determine if sacroiliac joint dysfunction is the source of your pain by conducting a physical examination. Besides reviewing your medical and family history, you will likely also be asked to engage in a few movement exercises. If you have no secondary conditions that can account for the pain you feel, and the movements your doctor has you do recreate the same pain you’ve been feeling, it is likely that sacroiliac joint dysfunction is the cause of your pain.
