The large joint that connects the base of the spine to the hip bones is called the sacroiliac joint. When that joint becomes painful, it can cause pain in that immediate region or a surrounding region. To relieve pain that is thought to be coming from the sacroiliac joint, patients may opt to get a sacroiliac (SI) joint injection. SI joint injections, also referred to as a sacroiliac joint block, is typically used to diagnose or treat lower back pain or sciatica symptoms associated with sacroiliac joint dysfunction. Also, the injection can help with confirming or denying whether the joint is in fact a source of a patient’s pain.
These pain management injections work powerfully to reduce inflammation and provide relief. A steroid medication and anesthetics mix is used for the injection - this solution has the effect of reducing both the pain in the joint and any surrounding inflammation.
How does the procedure work?
To begin the procedure, patients lie down on their stomach. Once in the correct position, the patient’s back will be cleaned with an antiseptic solution which is used to numb the skin. Then, the doctor will use X-ray guidance to gently direct a small needle into the joint and inject the anti-inflammatory steroid and anaesthetic solution. Once the injection is done, the needle is removed and the procedure is completed.
Following the procedure, a patient will remain in the office about 30 minutes. The patient will have their blood pressure and pulse monitored during that time. After that, if everything checks out fine, the patient will be discharged. **Note: It is important that all patients have someone to drive them home the day of the procedure.
And following the discharge, it is recommended by the pain management doctors that patients take it easy and only do light activities for a few days. Patients should focus on gradually building up their activity level.
