Sacroiliac Joint Injection
Sacroiliac Joint Injections are advanced nonsurgical diagnostic and pain relief treatments performed by the region’s leading pain management experts at Nassau Anesthesia Associates, P.C., a medical group affiliated with Winthrop-University Hospital on Long Island, NY.
In addition to providing anesthesia care for patients before, during, and after surgery, Nassau Anesthesia Associates has anesthesiologists with advanced training in the field of pain management. We utilize the most advanced nonsurgical techniques for treating acute and chronic pain that hasn’t responded to more conservative treatments.
The sacroiliac joint block is used to diagnose and treat low back pain associated with sacroiliac joint dysfunction. The two sacroiliac joints are located near the spine, connecting the sacrum with the hips on both sides. Pain is often the result of the joints becoming inflamed or dysfunctional.

SI Joint Injections for Diagnosis and Treatment
As a diagnostic tool, a sacroiliac joint block is used to determine if existing symptoms can be eliminated by numbing the nerve. If pain relief results from the injection, the suspected diagnosis of sacroiliac joint dysfunction is confirmed. Upon diagnosis, your doctor can then discuss with you the variety of treatment options that can help relieve the symptoms of this condition.
Your doctor might suggest that you combine ongoing sacroiliac joint injections with physical therapy, pelvic stabilization and manipulation therapy. The SI joint injections alone can help:
Reduce inflammation
Reduce swelling
Accelerate healing
Improve lower body function and mobility
Alleviate pain associated with the lower back, buttocks, groin and legs
