SI Joint Pain Treatment

Dysfunction in the sacroiliac joint, or SI joint, is thought to cause low back and/or leg pain. The leg pain can be particularly difficult, and may feel similar to sciatica or pain caused by a lumbar disc herniation.


Accurately diagnosing sacroiliac joint dysfunction can be difficult because the symptoms mimic other common conditions, including other mechanical back pain conditions like facet syndrome as well as other lumbar spine conditions including disc herniation and radiculopathy (pain along the sciatic nerve that radiates down the leg).

A diagnosis is usually arrived at through physical examination (eliminating other causes) and/or an injection (utilized to block the pain).

Injections to Determine the Source of Pain

A sacroiliac joint injection, sometimes called a sacroiliac joint block, can be a useful diagnostic test. It takes a highly skilled and experienced physician to be able to insert a needle into the correct portion of the sacroiliac joint. Because of this, the injection is usually guided by X-ray to make sure the joint is properly injected. Sometimes a dye is injected so that the joint is better visualized, which is called an arthrogram.
