If you’ve ever experienced lower back, hip, or leg pain, you may have heard of the sacroiliac (SI) joint. But what exactly is it, and why does it matter? The SI joint plays a crucial role in movement and stability, and when it’s not functioning properly, it can lead to discomfort and pain. Understanding its function and how to manage SI joint pain can be the key to long-term relief.

Where Is the SI Joint?

The sacroiliac joint is where your spine meets your pelvis. You have two SI joints—one on each side of your body. These joints connect the sacrum (the triangular bone at the base of your spine) to the ilium (the upper part of your pelvic bone). Despite being relatively small, the SI joints play a big role in your body’s overall function.

The Role of the SI Joint

The primary job of the SI joint is to transfer weight and forces between your upper body and your legs. It’s a strong, stable joint with minimal movement, but that limited mobility is crucial for absorbing shock and maintaining balance.

Think of the SI joint as the bridge between your spine and pelvis. Whether you’re walking, running, or lifting something heavy, this joint helps distribute the load efficiently and protects your body from strain. When this joint isn’t functioning properly, it can lead to inflammation, pain, and reduced mobility.

Common Problems with the SI Joint

SI joint dysfunction can be caused by a variety of factors, including injury, pregnancy, arthritis, or movement imbalances. Here are some of the most common issues:

1. SI Joint Dysfunction: This occurs when the joint moves too much (hypermobility) or too little (hypomobility). Either scenario can cause pain and inflammation.
2. Arthritis: Osteoarthritis or inflammatory arthritis can affect the SI joint, leading to stiffness and discomfort.
3. Pregnancy-Related Pain: During pregnancy, hormonal changes can loosen ligaments in the pelvis, including those around the SI joint, which may cause pain.
4. Trauma or Injury: Falls, car accidents, or other injuries can damage the SI joint or surrounding ligaments.

Signs and Symptoms of SI Joint Pain

SI joint pain can manifest in several ways, often mimicking other conditions like sciatica or hip issues. Here are some common symptoms:

• Pain in the lower back, buttocks, hips, or groin
• Discomfort when sitting for long periods or standing up from a seated position
• Pain that worsens with specific movements, like climbing stairs or getting in and out of a car
• A feeling of instability in the pelvis or lower back
