Sacroiliac Joint Injection

The sacroiliac (SI) joints are found at the base of the spine at the convergence of the sacrum and ilum bones. The joints where these two bones come together can become injured or inflamed, causing radiating pain, tingling, and other uncomfortable sensations in the lower back, hips, and lower extremities. Injections are given to both diagnose and manage sacroiliac joint pain, providing several weeks or months of symptomatic relief.


Did you know?

SIJ dysfunction is a very common cause chronic low back pain, often misdiagnosed as pain originating from degenerative disc disease and lumbar facet joints. Many patients with sacroiliac joint pain experience morning stiffness, which improves with activity, pain with prolonged sitting, car rides, and often find it necessary to readjust positions while sitting.

Am I a candidate for  sacroiliac joint injections?

A SI injection may be right for you if you have chronic or radiating pain stemming from some type of injury or agitation in the sacroiliac joints. Injections are generally reserved for patients who have not achieved significant pain relief from more conservative treatment measures. You should not undergo an SI injection if you are currently taking anti-coagulant medications or if you are suffering from any type of injection or illness at the time of your scheduled procedure. The only way to know for sure whether an SI injection is right for you is by scheduling a consultation with your doctor.

What should I expect during sacroiliac joint injection?

You will be awake during an SI injection, although the injection site will be anesthetized and you’ll have the option of being lightly sedated. Your doctor will use x-ray imaging to carefully guide a fine needle into the sacroiliac joint and administer the numbing or anti-inflammatory medication. The procedure takes just minutes to complete and is performed on an outpatient basis. You’ll need to rest for the remainder of the day at home, but can likely return to work soon after.

What types of results can I expect from a sacroiliac joint injection?

SI joint injections involve the use of slow-release medications that may take several days to begin taking effect. Once pain begins to subside, most patients can expect to experience several weeks, or even months of pain relief. Although SI joint injections cannot cure injuries or complications of the sacroiliac joints, they can significantly improve quality of life for a person suffering with chronic pain. If the injections provide significant, but temporary pain relief, than a radio frequency ablation treatment is an option that will provide much longer lasting pain relief. The Physicians at RA Pain services will discuss these treatment options with you.
