Sacroiliac Joint Injections

What is it?

The sacoiliiac joint is a weight-bearing joint between the pelvic bone and the tail bone (coccyx). It can be responsible for as much as 30% of all patients who experience back pain.

How it is performed

X-ray is used to help guide a needle into the joint. Once inside the joint a small amount of contrast dye is injected to make sure it was properly paced and inside the joint.

What patients are candidates?

Patients whose lower back pain is worsened with movement such as prolonged sitting, standing or transitioning from a sitting to a standing position.

How long does the procedure?

10-15 minutes


Following the injection, the patient may be monitored for 20-30 min before being discharged to go home. Patients are usually asked to rest on the day of the injection.
