What is a Sacroiliac (SI) Joint Injection?
A sacroiliac joint injection is a targeted injection to the joint of the sacrum and pelvic bones, meant to target lower back pain. The symptom that results from an impacted sacroiliac joint is often described as intense and localized pain in the buttock, leg, hip, groin, or abdomen areas. The combination of anesthetic and steroid agents in the injection is meant to lower inflammation and decrease pain levels. Additionally, sacroiliac joint injections can also be used as a diagnostic tool. A diagnostic SI joint injection can be employed to confirm a suspected diagnosis of sacroiliac joint dysfunction.
In this case, the physician will inject a local anesthetic into the joint. After a few moments, the physician will ask the patient to recreate the movement that usually causes triggers the pain. If the patient experiences significant relief for the duration of the anesthetic, a tentative diagnosis is made. During the second stage, the physician will inject a different numbing medication and conduct the same steps followed during the first injection. If the second injection also provides significant relief, there is now a reasonable degree of medical certainty for a sacroiliac joint dysfunction diagnosis.
