Diagnosing & Relieving SI Joint Related Back Pain
Sacroiliac (SI) joint dysfunction is a common source of pain in the lower back, buttocks, groin, and legs. These generalized symptoms, however, can be easily confused with other causes of back pain.
The SI joint injection enables physicians to confirm that irritation or damage to the SI joint is the source of your symptoms. This precise diagnostic tool is also a therapeutic procedure, offering significant pain relief.
How does SI joint injection help?
SI joints connect the pelvic bones to the spine. They are small and don’t move much, but they absorb all the forces of the upper body before balancing and transferring the weight to the hips and legs. When one or both of these joints become irritated or injured, they can cause chronic discomfort and pain.
SI joint injections can accurately pinpoint and alleviate this pain. Guided by fluoroscopy (x-ray imaging), your pain specialist injects a local anesthetic into the affected SI joint. If the anesthetic relieves your pain, this confirms the diagnosis. A corticosteroid medication is also injected. This long-acting medicine reduces inflammation and provides pain relief over an extended period of time.
How long does it take?
The procedure typically requires 20 to 30 minutes, including preparation time, and is followed by a short period of observed recovery time.
How often should this procedure be done?
Up to three injections may be given within a six-month time frame, usually performed two to three weeks apart. You may, however, gain considerable to complete relief after the first or second injection.
What are the expected results?
Immediate but temporary pain relief (lasting a few hours) may occur from the local anesthetic. The benefit from the corticosteroid medicine will typically occur two to four days following the procedure and last for several months.
Although they are not a cure, SI joint injections are very effective in reducing inflammation of the joint and providing considerable to complete pain relief for an extended period of time.
What should I do after the procedure?
We advise that patients take it easy for a day or so after the procedure. Perform only those activities that are easily tolerated by you.
