Sacroiliac Joint Injection

A sacroiliac joint injection is generally indicated for buttock pain, which may radiate to the thigh or lower leg. When diagnosing sacroiliac joint pain, there are several physical exam maneuvers that your clinician may have you perform. One of these maneuvers is the Patrick test or Faber maneuver. During this maneuver, you will lie on your back, and the heel of the painful side will be placed on the opposite knee. The clinician will then apply pressure on the flexed knee and the opposite buttock area. This test is considered positive for sacroiliac joint dysfunction if pain is elicited in the affected buttock.

​

Once the diagnosis of sacroiliac joint pain is made, you can schedule a sacroiliac joint injection. During this injection, medication is placed into the sacroiliac joint to help alleviate the buttock pain, which comes from this inflamed joint. The medication injected is generally a combination of steroids and anesthetics.
