Can sacroiliitis affect only one side?

Yes. Sacroiliitis can affect one sacroiliac joint or both joints. One-sided symptoms may stay near one buttock, while symptoms can spread when both joints are involved.

What does a sacroiliac joint injection target?

A sacroiliac joint injection targets the space around the painful joint. The medicine may reduce inflammation, while the response can provide information about the pain source.

Can an injury lead to sacroiliitis?

Yes. A fall, collision, or twisting injury can strain the sacroiliac joint. Repeated stress can also irritate the joint and produce similar symptoms.

Glossary

What Is Sacroiliitis?

Sacroiliitis is inflammation of one or both sacroiliac joints, which connect the lower spine with the pelvis. The condition can cause pain in the low back, buttocks, hips, or legs. Symptoms may worsen with standing, walking, climbing stairs, or changing position. Injury, arthritis, pregnancy, or repeated stress can affect these joints.

Quick Facts About Sacroiliitis

Key Takeaways About Sacroiliitis

Sacroiliitis affects the joints between the spine and pelvis.
Pain may spread from the buttock into the hip or leg.
Sacroiliitis is not the same as sciatica from nerve irritation.

How Sacroiliitis Works

Sacroiliitis develops when a sacroiliac joint becomes inflamed or irritated. These joints sit where the lower spine meets the pelvis. They help transfer force between the upper body and legs during movement.

A clinician checks the pain pattern, movement, and tenderness around the joint. Medical history and imaging may help rule out other causes. A sacroiliac joint injection can place medicine near the joint and may also help show whether the joint contributes to the pain.

The injection may include a numbing medicine and an anti-inflammatory medicine. Fluoroscopy can help guide needle placement during the procedure. Treatment choices depend on the examination and the suspected source of pain.

From the Premier Injury Specialists team

When we assess sacroiliitis, we compare the reported pain pattern with the examination findings. We also review imaging and injury history when those details are available. For a sacroiliac joint injection, our team focuses on accurate placement and records how symptoms respond.

Sacroiliitis in Practice: A Real-World Example

A person develops buttock pain after a vehicle collision, and standing makes the pain worse. The examination points toward the sacroiliac joint, so a sacroiliac joint injection may help assess and treat that pain.
