SI Joint Injections
What is it?
A sacroiliac (SI) joint injection, or a sacroiliac joint block, is primarily used to either diagnose or treat low back pain or sciatica symptoms. This pain is more prevalent in females, particularly those that have given birth, as childbirth can cause chronic pain in the pelvic joints.
How does it work?
A diagnostic SI joint injection is used to confirm a suspected diagnosis of sacroiliac joint dysfunction. This is done by numbing the sacroiliac joint with local anesthetic. The injection is performed under a live X-ray guidance, or fluoroscopy, for accuracy. Once the needle has entered the sacroiliac joint, contrast dye is injected to ensure proper needle placement and spread of medication. The anti-inflammatory steroid medication is then injected into the joint.
