What Are Sacroiliac (SI) Joint Injections?

SI Joint Injections involve precisely delivering a mixture of local anesthetic and/or corticosteroid medication into the sacroiliac joint under x-ray or ultrasound guidance. The goal is either diagnostic (identifying the SI joint as the pain source) or therapeutic (reducing inflammation and pain for lasting relief).

SI Joint Injections treat:

  • SI joint dysfunction, the most common cause due to excessive/insufficient movement.
  • Arthritis and inflammation from injuries, osteoarthritis, or ankylosing spondylitis.
  • Pregnancy-related SI joint pain and post-traumatic conditions.
  • Pain unresponsive to conservative treatments like medication, physical therapy, or manual therapy.

Ideal candidates are those who:

  • Have chronic lower back or leg pain suspected to originate from the SI joint.
  • Have failed to achieve relief with non-interventional approaches (medication, rehab, manual therapy).
  • Are seeking both diagnostic clarity and effective, minimally invasive pain relief.
  • In a study of 351 patients receiving fluoroscopically guided SI joint injections, 60.6% reported significant pain relief at 1 month, 42.1% at 3 months, and 32.5% at 12 months.
  • Physical function improved (PROMIS-GH scores) at 3, 6, and 12 months, indicating quality-of-life gains.
  • Effects on mental health, depression, and long-term disability were less robust, highlighting the importance of holistic care.

FAQs About Peripheral Nerve Blocks

What is a sacroiliac (SI) joint injection?

An SI joint injection is a minimally invasive procedure where a doctor injects anesthetic and sometimes steroid medication into the sacroiliac joint (where the spine meets the pelvis) to reduce inflammation and relieve lower back, hip, or buttock pain.

Doctors recommend SI joint injections to diagnose or treat sacroiliac joint pain. They are commonly used for patients with arthritis, injury, pregnancy-related pelvic pain, or chronic lower back pain that has not improved with other treatments.

Pain relief can start within hours and may last from a few weeks to several months, depending on the cause of pain and the individual’s response. Some patients require repeat injections for longer-lasting results.

Yes, SI joint injections are considered safe when performed under imaging guidance (like X-ray or ultrasound). Risks are low but may include temporary soreness, infection, bleeding, or an allergic reaction to the medication.

The procedure usually takes 15–30 minutes and is done on an outpatient basis. Most patients can walk shortly after, though mild soreness at the injection site is common. Normal activities can often be resumed within a day.

Studies show that many patients experience significant short-term to moderate long-term relief, especially when combined with physical therapy. Effectiveness varies, but injections are often part of a broader treatment plan for chronic SI joint pain.
