Sacroiliac Joint Injection

A Sacroiliac Joint Injection is designed to diagnose and reduce back pain related to sacroiliac dysfunction. The Sacroiliac (SI) joint is located where the sacrum meets the ilium (pelvis bone).

Patients with SI joint pain typically complain of low back, buttock pain and difficulty sitting down straight. Occasionally the pain may radiate to the posterior thigh. The onset is usually gradual unless trauma was involved.

SI injections are performed as an outpatient procedure with the aid of x-ray guidance (Fluoroscopy). Most often the SI injection is performed with local (numbing) anesthesia to the area. Patients may have one sided or bilateral SI pain. Patients are placed onto their stomach, and the skin overlying the joint is cleaned in a sterile fashion. A needle is advanced into the joint in real-time. Once the needle tip position is obtained, a small amount of contrast is injected into the SI joint for confirmation of proper placement.  A combination of numbing medication and steroid is injected into the joint.

The medication should then provide relief of the inflammation and pain. SI injections are low risk procedures. Complications may include bleeding, infection, nerve injury, or allergic reaction to any of the injected medications. Overall, patients do very well with this form of sacroiliac joint treatment. If the pain returns within a few months, consideration for RADIOFREQUENCY ABLATION of the sacroiliac joint may provide a longer duration of relief.
