Your sacroiliac (SI) joints are tissues that connect your ilium and sacrum. The SI joints are located at the bottom of your spine and are a part of your pelvis.

SI joint problems can be expressed by pain in the low back, hip, pelvis, groin, and buttock as well as buy pain, numbness, and weakness in the leg and foot.

Sacroiliac joint pain can also disrupt your sleeping and can cause difficulty sitting and standing.

Although 25% of low back pain comes from the SI joint, SI joint pain often is misdiagnosed as pain originating from your spine. Fortunately, Dr. Ahuja is familiar with SI joint problems and has a variety of diagnostic and treatment options available.

Diagnosing SI Joint Problems

SI Injection

An SI injection is a short procedure in which Dr. Ahuja injects a numbing medicine into the SI joint. During the procedure, Dr. Ahuja uses a video x-ray machine called a fluoroscope to guide him.

If your pain is significantly relieved by this injection, it would be clear that your pain is coming from a diseased SI joint.


There are certain exercises and movements designed to manipulate the SI joint. These manipulations may irritate the SI joint and cause pain. If pain results, it may be an indication of SI joint problems.

Treating SI Joint Pain

Dr. Ahuja will first try physical therapy, medication, and time to control your SI joint pain. If these treatments do not work to your satisfaction, Dr. Ahuja will recommend a sacroiliac joint fusion surgery.

In SI joint fusion surgery, a small incision is made on the side of the hip and three rods are placed into the SI joint. These rods will stabilize the SI joint, reducing irritation, inflammation, and, most importantly, your pain.

The surgery takes about an hour or less.
