The Procedure
You will be asked to lie face down on a procedure table, making sure you are comfortable and relaxed. The injection site will be cleaned thoroughly with an antiseptic solution to minimize the risk of infection, and a local anesthetic may be applied to numb the area, ensuring you feel minimal discomfort. Using fluoroscopic (X-ray) guidance, the specialist will carefully and precisely locate your SI joint to ensure accurate needle placement. This step is crucial for the success of the procedure, as it allows the specialist to see the joint in real-time and avoid any surrounding structures. A small needle, specifically designed for this type of procedure, will then be gently inserted into the joint, and the medication will be administered slowly to ensure proper distribution. The entire procedure typically takes about 20 to 30 minutes, and you will be monitored for a short time afterward to ensure you are comfortable and there are no immediate side effects.
