- Pain may spread into the buttock, hip, or lower back.
- Sacroiliac Dysfunction is not the same as sciatica.
How Sacroiliac Dysfunction Works

Sacroiliac Dysfunction changes how the joint shares movement and load between the spine and pelvis. Irritation can develop near the joint and surrounding tissues. Pain may stay near the joint or travel into the buttock and upper leg.

Clinicians review the pain pattern, body movements, and findings from a physical exam. Fluoroscopy may guide a sacroiliac joint injection so medication reaches the intended area. The response can help show whether the joint contributes to the pain.
How Sacroiliac Joint Injections Fit
A sacroiliac joint injection places medication near the joint. The procedure may provide relief and give the care team more information about the pain source. Results are considered with the exam and the person's symptoms.

From the Premier Injury Specialists team
When we assess Sacroiliac Dysfunction, we connect the reported pain pattern with movement findings and the physical exam. When we perform a sacroiliac joint injection, we use image guidance and track the person's response as part of the clinical picture.
