Sacroiliac (SI) Joint Dysfunction

What is SI joint dysfunction?

The sacroiliac (SI) joints connect the base of the spine (sacrum) to the pelvis. These joints play a crucial role in absorbing shock and transferring weight between the upper body and legs. SI joint dysfunction occurs when these joints become inflamed, irritated, or move abnormally, leading to lower back pain, hip pain, or discomfort that can mimic other spine conditions.

Signs & symptoms of SI joint dysfunction

SI joint pain can often be mistaken for other types of back or hip problems. Common symptoms include:

• Pain in the lower back, buttocks, hips, or groin
• Pain that worsens with standing, walking, or climbing stairs
• Discomfort that improves when lying down
• Stiffness or decreased mobility in the hips and pelvis
• Pain that radiates down into the thighs (similar to sciatica)

Causes & risk factors

Several factors can contribute to SI joint dysfunction, such as:

• Arthritis – Wear and tear in the joint can cause inflammation and stiffness.
• Pregnancy – Hormonal changes and increased joint movement can lead to SI pain.
• Injury – Trauma from falls, accidents, or repetitive stress may irritate the joint.
• Abnormal walking patterns – Leg length differences, hip issues, or back problems can place extra stress on the SI joint.
• Previous spine surgery – Especially lumbar fusion, which increases strain on the SI joints.

Diagnosing SI joint dysfunction

Because SI joint pain can mimic other conditions like herniated discs or hip arthritis, a precise diagnosis is important. At Iowa Ortho, diagnosis may include:

• Physical exam – Assessing pain with specific movements or joint pressure.
• Imaging tests – X-rays, MRI, or CT scans to rule out other causes of pain.
• Diagnostic injections – Numbing medication is injected into the SI joint to confirm it as the source of pain.

SI joint dysfunction treatment options

Treatment is personalized depending on the severity of symptoms and the underlying cause. Iowa Ortho offers both non-surgical and surgical treatment options.

Non-surgical treatments

• Physical therapy – Exercises to strengthen core and pelvic muscles.
• Medications – Anti-inflammatory drugs or pain relievers.
• SI joint injections – Corticosteroid injections to reduce inflammation and pain.
• Radiofrequency ablation – Targeted heat therapy to disrupt pain signals from the SI joint.
• Lifestyle modifications – Activity changes, weight management, and supportive braces.

Surgical treatment for SI joint dysfunction

If conservative care does not provide lasting relief, SI joint fusion surgery may be considered. This procedure stabilizes the joint, reducing abnormal movement and chronic pain. Iowa Ortho’s orthopedic surgeons use advanced techniques designed to improve outcomes and shorten recovery times.
