A diagnostic and therapeutic injection into the sacroiliac or other joint can provide short or long-term pain relief.

How it's performed
Usually using a fluoroscope for guidance, a needle is introduced into the correct portion of the sacroiliac or other joint. The position may be confirmed by injecting a small amount of contrast dye. The local anesthetic and anti-inflammatory steroid is injected. Local injections into the ligaments may be helpful. The procedure usually lasts 10-20 minutes.
