Condition Definition

The SI joints connect sacrum to pelvis and transfer load from trunk to legs. Inflammation, instability, or degeneration in these joints can produce significant lower back/buttock pain.

Common Causes

Contributors include pregnancy/postpartum changes, prior lumbar fusion, inflammatory disease, trauma, repetitive asymmetric loading, and degenerative SI joint change.

Typical Symptoms

Pain is often one-sided below the beltline, radiating to buttock/hip/groin and aggravated by transitions, stairs, prolonged sitting, or single-leg loading.

SCOPES Clinical Approach

At SCOPES Health, image-guided SI injections serve both diagnostic and therapeutic roles. Patients with strong positive response and recurrent pain are evaluated for SI RFA, with pelvic stability rehabilitation integrated into care.

Frequently Asked Questions

How is SI joint pain confirmed?

Image-guided diagnostic SI injection with significant temporary relief confirms SI contribution to pain.

Is SI pain the same as sciatica?

No. SI pain may mimic sciatica but often stays above the knee and does not follow a classic dermatomal pattern.
