What Is the Sacroiliac (SI) Joint?
Definition and Location
The sacroiliac joint connects the sacrum, the triangular bone at the base of your spine, to the ilium bones of the pelvis. These joints are located on either side of the lower back, just above the buttocks. They serve as critical stability points that support the upper body's weight during movement.
Function of the SI Joint
The primary roles of the SI joints include:
- Absorbing shock between the upper body and legs
- Allowing slight movements to facilitate walking, bending, and twisting
- Providing stability and support during physical activity
Common Causes of SI Joint Dysfunction
Understanding the root causes of SI joint problems is vital for effective treatment. Several factors can contribute to SI joint pain or instability, including:
Injuries and Trauma
- Falls or direct blows to the pelvis
- Sudden movements or accidents causing strain
Pregnancy and Hormonal Changes
Pregnancy can loosen ligaments around the SI joint, leading to instability and pain.
Degenerative Conditions
Conditions such as osteoarthritis can wear down the cartilage and joint surfaces.
Biomechanical Issues
Poor posture, leg length discrepancies, or abnormal gait can strain the SI joint.
Inflammatory Conditions
Autoimmune diseases like ankylosing spondylitis may cause inflammation in the SI joints.
Symptoms Indicating SI Joint Problems
Recognizing the symptoms can help determine if your discomfort stems from SI joint issues. Common signs include:
- Lower back pain that may radiate to the buttocks, hips, or groin

The Harvard Medical School Guide to Healing Your SI: A Comprehensive Approach to Sacroiliac Joint Health
The Harvard Medical School Guide to Healing Your SI offers a groundbreaking, evidence-based roadmap for understanding and alleviating sacroiliac (SI) joint pain. As one of the less understood sources of lower back discomfort, SI joint dysfunction affects millions globally, often leading to chronic pain, limited mobility, and diminished quality of life. This guide synthesizes the latest research, clinical insights, and practical strategies to help patients, clinicians, and caregivers navigate the complex journey toward SI joint health and healing.
Understanding the Sacroiliac Joint: Anatomy and Function
What Is the SI Joint?
The sacroiliac (SI) joint is a critical but often overlooked structure located at the base of the spine, connecting the sacrum (the triangular bone at the back of the pelvis) to the iliac bones (the large, wing-shaped bones forming the pelvis). This joint functions as a shock absorber and stabilizer during movement, bearing significant loads when standing, walking, or lifting.
Anatomy of the SI Joint
The SI joint is a synovial joint, featuring:
- Articular surfaces: Roughly 17-25 degrees of surface convexity on the sacrum and corresponding concavity on the ilium.
- Ligaments: A network of strong ligaments (anterior, posterior, interosseous, and iliolumbar ligaments) that provide stability.
- Synovial fluid: A thin layer of fluid facilitating minimal movement, which is essential for shock absorption.
Functionality and Biomechanics
The SI joint's primary role is to transmit forces from the upper body to the lower limbs. During gait, it undergoes subtle movements—nutation (forward tilt) and counternutation (backward tilt)—which are crucial for pelvic stability and mobility.
Common Causes and Symptoms of SI Joint Dysfunction
Causes of SI Joint Pain
SI joint pain can arise from diverse factors:
- Trauma or Injury: Accidents, falls, or sudden impacts can damage ligaments or joint surfaces.
- Pregnancy: Hormonal changes increase ligament laxity, and the added weight stresses the joint.
- Degenerative Changes: Osteoarthritis can cause cartilage breakdown, leading to pain.
- Inflammatory Conditions: Conditions like ankylosing spondylitis and other spondyloarthropathies.
- Biomechanical Imbalances: Leg length discrepancies, scoliosis, or muscular imbalances.
- Repetitive Stress: Activities involving repetitive twisting, lifting, or twisting motions.
Recognizing the Symptoms
SI joint dysfunction manifests through:
- Localized Pain: Usually on one side of the lower back or buttocks.
- Radiating Discomfort: Pain may radiate down the thigh, groin, or into the lower extremities.
- Aggravation with Movement: Standing up after prolonged sitting, climbing stairs, or certain movements exacerbate pain.
- Tenderness: Palpation over the joint reproduces discomfort.
- Reduced Mobility: Stiffness and limited range of motion.
Diagnostic Strategies: Pinpointing SI Joint Dysfunction
Clinical Evaluation
A thorough history and physical exam are essential. Key assessments include:
- Pain Provocation Tests: Such as FABER (Flexion, Abduction, External Rotation), Gaenslen’s test, and SI compression/distraction tests.
- Functional Tests: Observing gait, posture, and movement patterns.
- Palpation: Identifying tenderness over the SI joint.
Imaging Modalities
While imaging cannot always confirm SI joint pain, it helps rule out other causes:
- X-Rays: To detect arthritis, fractures, or structural anomalies.
- MRI: Offers detailed visualization of soft tissues, inflammation, or sacroiliitis.
- CT Scans: Useful for detailed bone assessment, especially before injections or surgery.
Diagnostic Injections
The gold standard for confirming SI joint pain involves local anesthetic injections:
- Procedure: Anesthetic is injected into the SI joint under imaging guidance.
- Interpretation: Significant pain relief indicates the SI joint as the pain source.
Evidence-Based Treatments for SI Joint Dysfunction
