SI Joint Injections

October 26, 2016

The sacroiliac joint is located where the spine and the hip bone meet. Often, a sacroiliac (SI) joint injection is administered to the SI joint to reduce pain in the lower back. Using a needle, small amounts of steroids and a local anesthetic are injected into the sacroiliac joint. The injections are often used to diagnose or treat low back pain or sciatica symptoms associated with sacroiliac joint dysfunction. From a diagnostic standpoint, if you experience 75% to 80% pain relief from this injection, there is a reasonable degree of certainty the sacroiliac joint is the source of your pain. If the injection is effective in alleviating your back pain, it can be administered up to 3 times per year.

On the day of the injection, do not drive and avoid doing any strenuous activities. On the day following the procedure, you can return to your regular activities.
