Back Pain

Sacroiliac Joint Pain


Sacroiliac joints are the joints connecting the spine to the hips. The two joints provide support and stability and have a major role of absorbing shock in the back and hips. Usually, there are two dimples in your lower back which represent where the SI joints are located. The SI joint is a synovial joint filled with fluid. This type of joint has free nerve endings that can cause chronic pain if the joint degenerates or does not move properly. Acute SI joint pain occurs suddenly and usually heals within several days to weeks. Chronic SI joint pain persists for more than three months; it may be felt all the time or worsen with certain activities. The SIJ is notoriously hypomobile, meaning that it is capable of very little movement. The SIJ has strong ligaments and muscles connecting the two bones together and can be overstretched, sprained, or strained if stretched too far. Therefore, SIJ pain cand be degenerative or acute in nature.

How to Diagnose

A medical exam will determine where the source of pain is coming from as well as a thorough medical history. There are specific tests designed to reveal if the SIJ is responsible and you may be asked to put yourself in odd positions to put it under a little bit of stress. Imaging studies such as x-rays, MRI’s, or CT scans can be used confirm diagnoses.
