Sacroiliac Joint Dysfunction
Sacroiliac (SI) joint dysfunction refers to pain arising from the sacroiliac joints, which connect the spine to the pelvis. These joints have limited motion but absorb significant forces during walking, running, and lifting. SI joint problems can cause low back, buttock, and leg pain that mimics other conditions.
Prevalence
SI joint dysfunction is implicated in 15-30% of chronic low back pain cases. It is often underdiagnosed because symptoms overlap with other spinal conditions.
Who It Affects
Common in adults, particularly those with leg length discrepancy, gait abnormalities, previous lumbar fusion, or pregnancy. Athletes and those with physically demanding jobs are at increased risk. Women are affected more often than men.

Common Symptoms
Common Causes & Risk Factors
Traditional Treatment Options
Physical Therapy
Exercises to stabilize the pelvis, strengthen supporting muscles, and correct imbalances.
Limitations: Requires consistent effort. May not resolve symptoms from significant joint degeneration.
SI Joint Injections
Corticosteroid injection directly into the SI joint for diagnosis and treatment.
Limitations: Diagnostic value helps confirm SI source. Therapeutic relief is often temporary.
SI Joint Belt
External support to compress and stabilize the SI joints.
Limitations: Provides symptomatic relief but doesn't address underlying joint pathology.
SI Joint Fusion
Surgical fusion of the sacroiliac joint to eliminate painful motion.
Limitations: Surgery with recovery time. Eliminates joint motion. Results vary.
Regenerative Medicine Approach
How Regenerative Therapy May Help
Regenerative medicine for SI joint dysfunction explores whether biologics may help support joint health and reduce inflammation in the sacroiliac joints. The approach aims to deliver growth factors directly to these weight-bearing joints that are challenging to treat conservatively.
Potential Benefits Being Studied:
- May help reduce inflammation in the SI joint
- Contains growth factors that support joint health
- Precise delivery under fluoroscopic guidance
- Minimally invasive compared to SI fusion
- May provide longer benefit than steroid injections
- An option when conservative treatments provide inadequate relief
Biologics Used:
Exosomes delivered intra-articularly to the SI joint
Mesenchymal stem cells with joint-supporting properties
Frequently Asked Questions
How do you know my pain is from the SI joint?
SI joint pain is diagnosed through a combination of history, physical examination maneuvers, and diagnostic injection. If an anesthetic injection into the SI joint temporarily relieves your pain, it confirms the SI joint as a pain source.
Can both SI joints be treated?
Yes, if both joints are identified as pain sources through diagnostic testing, both can typically be treated. Your provider will determine the appropriate approach based on your evaluation.
How does this compare to SI joint fusion?
Regenerative therapy is minimally invasive and preserves joint motion. Fusion is a surgical procedure that eliminates joint motion. Some patients try regenerative approaches before considering fusion surgery.
