What is it?

The sacrum forms the posterior pelvic wall and provides the pelvis stability and strength. It is located at the base of the lumbar vertebrae. The sacroiliac joint connects the hip bones to the sacrum and functions as a shock absorber between the upper body, the pelvis and the legs. Sacroiliac joint instability may cause lower back pain. Causes and risk factors for sacroiliac joint dysfunction include leg length discrepancy or scoliosis, pregnancy, recent childbirth, prior low back surgery, contact sports, regular heavy lifting, trauma or injury.

Symptoms may include dull, aching, one or two sided on the lower back. The pain may spread to the hips, buttocks, and/or groin. Stiffness and reduced range of motion on the lower back, hops, pelvis and groin may be felt when walking up the stairs or during other movements.


Diagnosis is made upon findings from medical history, physical examination, imaging tests such as X-ray, CT, or MRI.


Treatment may include nonsurgical treatments such as physical therapy, chiropractic manipulation, stretching exercises and medications such as pain relievers, anti-inflammatory, topical patches, creams or mechanical bracing. Steroids can be given by injection. Nerve blocking may also be recommended. If the non surgical treatment fails, surgery may be an option as well.
