Interventional Pain Management

Sacroiliac Joint Injection

A targeted injection directly into the sacroiliac joint to diagnose and treat SI joint dysfunction, one of the most common and underdiagnosed causes of low back and buttock pain.

What Is Sacroiliac Joint Injection?

A sacroiliac (SI) joint injection delivers a corticosteroid and anesthetic directly into the SI joint, which connects the sacrum (base of the spine) to the iliac bones of the pelvis. SI joint dysfunction is responsible for an estimated 15 to 30 percent of low back pain cases and is frequently mistaken for lumbar disc disease or hip pathology.

How It Works

Using fluoroscopic guidance, the physician guides a needle precisely into the SI joint space and injects a mixture of local anesthetic and corticosteroid. The anesthetic provides immediate diagnostic confirmation and short-term relief, while the steroid reduces joint inflammation for longer-lasting benefit.

01

Evaluation

Physical examination and provocative tests help identify SI joint pain. Imaging is reviewed.

02

Positioning

You lie face down. The sacroiliac joint is identified under fluoroscopy.

03

Needle Placement

The physician guides the needle into the SI joint under real-time X-ray guidance.

04

Injection

Contrast dye confirms correct placement, then anesthetic and steroid are injected.

05

Recovery

You rest briefly and track your pain response over the following hours.
