Sacroiliac Joint Injections

Sacroiliac joint injections

Sacroiliac joint injections are used to either diagnose or treat lower back pain and/or sciatica symptoms associated with sacroiliac joint dysfunction. There are two sacroiliac joints, both on either side of the spine. Inflammation and/or dysfunction can cause pain. The injection to either diagnose or treat the pain is commonly combined into one injection.

1. Diagnosis

To determine the cause of the pain an injection is performed under Fluoroscopy for accuracy. The sacroiliac joint is numbed with a local anesthetic and then the guided needle is inserted into the sacroiliac joint, contrast is injected into the joint to ensure correct placement of the needle and medication. Once everything is in place the numbing medication is injected.

Once the medication is injected the patient is asked to try and reproduce the original pain by performing normal activities. If the patient experiences high pain relief while performing normal activities, a tentative diagnosis of sacroiliac joint dysfunction is made. A second diagnosis is made using another numbing medication for accuracy.

2. Pain Relief

The injection is administered the same way it was during diagnosis, except anti-inflammatory medication is included to provide pain relief by reducing inflammation.

If the injection is successful and the pain subsides then the patient can start the rehabilitation process and pain relief injections can be administered up to three times per year.
