Sacroiliac joint dysfunction, or sacroiliitis, occurs when the joints connecting the lower spine to the pelvis become inflamed or move abnormally, causing pain and stiffness. It accounts for about 30% of low back pain. These sacroiliac (SI) joints help stabilize the body and absorb impact, but if they move too much, too little, or become irritated, they can lead to discomfort affecting daily activities. Diagnosis starts with a physical exam to evaluate pain response. Imaging tests, like X-rays or MRIs, may rule out serious conditions but are rarely needed. Diagnosis relies on exam findings and diagnostic injections to confirm the sacroiliac joint as the pain source.

Various factors contribute to sacroiliac joint dysfunction. Falls, car accidents, sports injuries, pregnancy-related hormonal changes, arthritis, and aging can strain the joint. Sometimes, leg length differences or autoimmune diseases may contribute to the issue.

People often feel pain in the lower back, buttocks, or thighs, usually on one side. Pain may worsen with sitting, climbing stairs, or standing from a seated position. Some experience stiffness or instability when changing positions.

Treatment focuses on reducing pain and restoring function. Physical therapy strengthens muscles and improves flexibility, while medications reduce discomfort. Injections or radiofrequency ablation may relieve nerve irritation. Surgery is rare and considered only if other treatments fail.

Additionally, regenerative treatments like platelet-rich plasma (PRP) injections may promote healing. If you’re experiencing persistent lower back or pelvic pain, early treatment can improve mobility and prevent long-term issues. Talk to our team to find the best treatment plan for you.
