Sacroiliitis
Don’t let sacroiliitis keep you from walking comfortably, exercising, or enjoying daily life. At Compass Pain and Wellness, we combine advanced diagnostic medicine with cutting-edge treatments to address the root cause of sacroiliac joint pain—not just the symptoms.
Overview
What Is Sacroiliitis?
Sacroiliitis refers to inflammation of one or both sacroiliac (SI) joints, which are located where the spine meets the pelvis. These joints play an important role in transferring forces between the upper body and the legs during movement. When the SI joint becomes inflamed or irritated, it can cause pain in the lower back, buttocks, hips, or even down the legs.
The sacroiliac joints are designed to provide stability while allowing only small amounts of movement. However, when inflammation develops within the joint, it can disrupt this balance and lead to persistent pain and stiffness. According to the Mayo Clinic, sacroiliitis can cause pain in the buttocks or lower back and may worsen with prolonged standing, stair climbing, or running.

Expert Analysis
Understanding Sacroiliitis
The sacroiliac joints connect the sacrum—the triangular bone at the base of the spine—to the iliac bones of the pelvis. These joints are reinforced by strong ligaments and muscles that help stabilize the body during walking, bending, and lifting. When inflammation develops in this area, it can interfere with normal movement patterns and place stress on surrounding structures.
Patients with sacroiliitis often experience pain in the lower back, buttocks, or back of the hips, which may worsen when standing up from a seated position, walking long distances, or climbing stairs. Some individuals also report stiffness, reduced mobility, or pain that radiates into the groin or down the leg. If left untreated, chronic SI joint inflammation can contribute to ongoing pain, altered gait mechanics, and strain on the lower spine and hips.
Triggers
Sacroiliitis can develop for several different reasons, but it most commonly occurs due to mechanical stress or inflammation affecting the sacroiliac joints. Trauma from falls, car accidents, or sports injuries may irritate the joint and surrounding ligaments. Repetitive stress from activities such as running, lifting, or prolonged standing may also contribute to inflammation over time.
Other causes include pregnancy-related changes in pelvic stability, arthritis affecting the spine, or structural imbalances that alter the way forces move through the pelvis. Certain inflammatory conditions—such as ankylosing spondylitis—can also affect the sacroiliac joints. The Cleveland Clinic notes that sacroiliac joint inflammation may occur due to injury, arthritis, or abnormal joint movement that stresses the SI joint structures.

Differential Diagnosis
Pain in the lower back and hips can originate from many different structures, which makes accurate diagnosis critical. Sacroiliitis is often mistaken for lumbar disc herniation, sciatica, hip joint arthritis, piriformis syndrome, or facet joint arthritis in the spine. Because these conditions can produce similar pain patterns, identifying the exact source of pain is essential before beginning treatment.
At Compass Pain and Wellness, precise diagnosis is the cornerstone of effective care. Our board-certified physicians use advanced diagnostic tools such as flexion and extension X-rays, structure-specific diagnostic ultrasound imaging, MRI scans, nerve conduction velocity testing, bloodwork, and targeted diagnostic injections to pinpoint the true pain generator. By carefully determining whether the sacroiliac joint itself is responsible for the symptoms—or if another structure is involved—we can create a treatment plan tailored to the patient’s specific condition.
Solutions
Treating sacroiliitis effectively requires addressing both the inflammation within the sacroiliac joint and the biomechanical factors that contribute to joint irritation. At Compass Pain and Wellness, we develop personalized treatment plans that combine advanced interventional procedures, regenerative medicine, and supportive therapies designed to restore joint stability and reduce long-term pain.

What Makes Compass Different
Many patients with sacroiliac joint pain struggle with persistent symptoms because the true source of their pain is never clearly identified. At Compass Pain and Wellness, our care begins with world-class diagnostic medicine. Our physicians take the time to understand each patient’s story and perform comprehensive evaluations using advanced imaging and diagnostic techniques to determine exactly what structure is causing the pain.
Once the diagnosis is confirmed, we combine advanced regenerative medicine with a multidisciplinary approach to care. Treatments such as platelet-rich plasma and cellular therapy are delivered under precise ultrasound and fluoroscopic guidance to stimulate healing within damaged structures. Patients also benefit from coordinated care that includes physical therapy, chiropractic care, acupuncture, massage therapy, and advanced technologies like photobiomodulation, PEMF, and shockwave therapy—all designed to support long-term recovery and functional improvement.
