Sacroiliac joint pain is a big reason for low back pain, hitting 10-33 percent of people with chronic pain. The sacroiliac joints link the spine’s base (sacrum) to the pelvis (iliac bones). They act as shock absorbers during physical activities.
Knowing how these joints work is key to figuring out and fixing pain. They help move weight from the upper body to the legs. When they don’t work right, it can hurt a lot.
At Liv Hospital, we aim to find the right diagnosis and offer new ways to help with sacroiliac joint pain.
Key Takeaways
- Sacroiliac joint pain is a common cause of low back pain.
- The sacroiliac joints connect the sacrum to the pelvis.
- Dysfunction in these joints can lead to significant discomfort.
- Understanding the anatomy and function is key for diagnosis and treatment.
- Liv Hospital provides accurate diagnosis and innovative care pathways.
Where Are Sacroiliac Joints Located: Anatomy and Function
The sacroiliac joints are between the sacrum and ilium bones. They are key for weight transfer and movement. The SI joint supports the body’s weight and helps the spine and legs move.
Anatomical Position of the SI Joint
The SI joints are on either side of the sacrum, linking it to the ilium bones. This setup helps distribute forces from the upper body to the lower limbs. The sacroiliac joints are the link between the spine and the pelvis, helping us stand and move well.
Your sacroiliac joint is between the sacrum and ilium. It’s in a strategic spot to handle body weight and allow for some movement.
How the Sacroiliac Joint Works
The SI joint transfers weight from the upper body to the lower limbs. It does this with strong ligaments and muscles for stability. The joint’s limited motion helps absorb shock and reduce stress on the spine and pelvis.
The ligaments around the SI joint are very strong. They support the joint under different loads. The joint’s anatomy and function work together closely. Problems can cause pain and dysfunction, like lower back or hip pain.
| Component | Function |
| Sacroiliac Joint | Transfers weight from upper body to lower limbs |
| Ligaments | Provides stability and support |
| Muscles | Assists in stabilizing the joint |
Knowing about the sacroiliac joint’s anatomy and function is key for treating SI joint pain. Healthcare providers can create better treatment plans by understanding its role in our body.
Common Symptoms of SI Joint Problems
Knowing the symptoms of SI joint dysfunction is key for the right diagnosis and treatment. The sacroiliac joint can lead to various symptoms when it’s not working right. This affects many parts of a patient’s life.
Pain Patterns and Distribution
Pain from the SI joint can show up in different ways. People often feel lower back pain, buttock pain, and hip pain. The pain can feel aching, stabbing, or sharp. It often spreads to the buttocks, hips, groin, or upper thighs.
The way pain spreads can differ a lot between people. Some feel pain on one side, while others feel it on both. Standing, sitting, or climbing stairs can make the pain worse.
- Pain in the lower back and buttocks
- Aching or sharp pain radiating to the hips and groin
- Discomfort or stiffness in the morning
SI Joint Tenderness and Physical Signs
Aside from pain, tenderness in the sacroiliac area is a big sign of SI joint dysfunction. Physical signs include:
- Tenderness to the touch over the SI joint
- Pain upon palpation (pressing on the joint)
- Inflammation or swelling in the affected area
Doctors often do special tests to check the SI joint’s function and tenderness. These tests help figure out if the SI joint is causing the pain.
It’s important to know these symptoms to tell SI joint dysfunction apart from other lower back pain causes. By understanding the pain patterns and physical signs, doctors can create a good treatment plan.
What Causes Sacroiliac Joint Pain: Risk Factors
Many things can cause sacroiliac joint pain. This includes mechanical, hormonal, and age-related changes. Knowing these factors is key to finding the right treatment.
Mechanical and Traumatic Causes
Getting hurt in an accident can lead to pain in the sacroiliac joint. This pain can come from a fall, a car crash, or any direct hit to the joint. Repetitive stress from heavy lifting, bending, or twisting also strains the SI joint, causing pain over time.
Jobs or sports that are very physically demanding can increase the risk of SI joint pain. This is because the joint is under constant strain.
Pregnancy and Hormonal Factors
Pregnancy is a big risk factor for SI joint pain. Hormonal changes make the ligaments looser, allowing the joint to move more. This extra movement can put abnormal stress on the joint, causing pain. Also, the weight gain during pregnancy puts more strain on the SI joint.
Women with SI joint pain during pregnancy might find relief by changing their sleeping positions. Using supportive pillows or adjusting how they sleep can help ease the pain.
Age, Previous Surgery, and Other Contributors
Age is a big factor, as the sacroiliac joint wears out over time. This wear and tear can cause pain and stiffness. Degenerative changes, like those in osteoarthritis, also contribute to SI joint pain.
Having had spinal surgery or a lumbar fusion can change how the lower back works. This can put more stress on the SI joint, leading to pain. Knowing these risk factors helps doctors tailor treatments to each person’s needs.
By understanding the causes of sacroiliac joint pain, healthcare providers can create better management plans. This improves how well patients do.

FAQ’s:
Where are the sacroiliac joints located?
The sacroiliac (SI) joints are located between the sacrum and the iliac bones on either side of the lower spine.
What is the function of the sacroiliac joint?
The SI joint stabilizes the pelvis, absorbs shock, and allows limited movement between the spine and pelvis.
What causes sacroiliac joint pain?
Causes include injury, arthritis, pregnancy, repetitive strain, poor posture, or abnormal gait mechanics.
What are the common symptoms of SI joint dysfunction?
Symptoms include lower back or buttock pain, stiffness, limited mobility, and pain when standing, walking, or climbing stairs.
How is SI joint pain diagnosed?
Diagnosis involves physical exams, pain provocation tests, and imaging such as X-rays, CT scans, or MRI.
Can pregnancy cause SI joint pain?
Yes, hormonal changes and increased pelvic stress during pregnancy can lead to SI joint pain.
How does age affect the sacroiliac joint?
Aging can cause degenerative changes, reduced joint flexibility, and increased risk of inflammation or arthritis.
What is the impact of previous surgery on SI joint pain?
Prior pelvic or spinal surgery can alter biomechanics, sometimes increasing stress and pain in the SI joint.
What are the best sleeping positions for SI joint pain?
Sleeping on the back with a pillow under the knees or on the side with a pillow between the knees can reduce SI joint strain.
How can SI joint pain be managed?
Management includes physical therapy, core strengthening, medications, injections, lifestyle modifications, and sometimes surgery.
