Sacroiliac Joint Injection
A sacroiliac joint injection involves the injection of steroid medication and an anesthetic into the joint and capsule of the sacroiliac joint. The sacroiliac joints are paired structures (on the right and left) that connect the spine to the pelvis and allow for motion.
The goal of the injection is to treat the pain in your low back, buttock, or upper leg and to help improve your spine motion. The injection will also assist in determining if your sacroiliac joint is your pain generator. It can also help guide future treatment.
All injections are performed under fluoroscopy (x-ray) or ultrasound-guidance or both.
What can you expect after the injection?
Pain relief may begin immediately after the medication has been injected. You may experience a brief recurrence of your former pain until the anti-inflammatory medication takes effect.
