What treatments are available for Sacroiliac joint pain?

For lesser pain, OTC medications like Ibuprofen, Naproxen sodium, and Acetaminophen may help somewhat, but for chronic conditions your doctor may prescribe opioid analgesics or sacroiliac block injections (also called a sacroiliac joint block). For conditions non-responsive to injections the patient may be a candidate for a radiofrequency nerve ablation.

The general progression is if the SI joint injection works and wears off, then either a repeat injection is indicated or the radiofrequency procedure is performed to obtain longer term pain relief.

What are expectations when a patient receives a sacroiliac joint injection?

The patient has a reasonable expectation of experiencing some level of pain relief from this procedure. Over 50% of patients achieve at least 50% pain relief. And the pain relief usually lasts for a few weeks to a few months.

How is the sacroiliac joint injection performed?

The patient is placed on an exam table, the area to be injected is cleansed with antiseptic solution and then topical anesthetic is used to numb the area to be injected. Using fluoroscope guidance (a type of x-ray machine) to ensure proper needle placement, the needle is then inserted into the area to be injected. A contrast dye is then injected to ensure the proper nerves are being treated, and then the numbing medications, a mixture of local anesthetic and a corticosteroid are injected. Often the patient will experience immediate temporary relief from the local anesthetic, but it can take two to three days for the steroid to be effective.
