What is a CT-Guided Sacroiliac (SI) Joint Injection?

This procedure is performed to treat inflammatory Sacroiliac joints, which are located in the lower back, using a steroid. The steroid is injected directly into the SI joint and includes both a corticosteroid and an anesthetic numbing agent. This injection is inserted using CT guidance to ensure accuracy. This procedure is generally for patients who have a long history of low back pain that is not relieved by non-steroidal anti-inflammatory or other medication. This procedure offers two potential benefits: alleviating pain and identifying its source.

For most joint injections, your physician can insert a needle into the joint using a standard X-ray. Since this is a more difficult joint to access, Jefferson performs the exam using CT to ensure accuracy.
