Specialist Decision Guide
Which spine doctor for Sacroiliac Joint Dysfunction?
SI joint dysfunction causes low back, buttock, and sometimes groin pain. Patients are commonly evaluated by a physiatrist who can perform a structured examination to distinguish SI joint pain from disc or facet sources. Targeted physical therapy (with pelvic girdle stabilization) and diagnostic SI joint injections are first-line approaches.
