At the lower end of the spine lies the Sacrum.
The Sacrum is a triangular shaped bone formed by the fusion of several smaller bones. The Sacroiliac (SI) joint sits between the Sacrum and the Ilium.
The Sacroiliac joint has an irregular surface and has very little motion.
The older one gets, the less motion occurs in the joint. This can create a significant amount of pain and loss of mobility.
Sacroiliac joint problems are one of many causes of low back pain. Sacroiliac joint dysfunction may be difficult to diagnose. X-rays, CAT scans and MRIs may be normal and several other problems can mimic the pain of SI joint dysfunction. One maneuver called the FABER test can provoke pain caused by SI joint problems. With this maneuver, the patient is lying down and our physician flexes, abducts and externally rotates the hip. If this maneuver reproduces the pain, then the sacroiliac joint may be the problem. If the diagnosis is still unclear, an injection into the joint may give the answer.
Initially, conservative treatment is prescribed. This consists of rest, anti-inflammatory medications and physical therapy. If this is not successful, an injection into the joint may help. As pain specialists, we perform this procedure using X-Ray guidance.
Our pain providers will discuss in detail what to expect and the treatment plan regarding SI joint injections and pain.
