A normal SI joint can move forward and downward (nutation) and backward and upward (counternutation). The primary mechanisms of SI joint dysfunction include: Too much movement (hypermobility or instability) in the sacroiliac joint can cause …

2023年10月5日 · Sacroiliac (SI) joint dysfunction describes pain due to abnormal movement (too much or too little) or misalignment of the SI joint. It can cause sharp, stabbing pain that starts in the hips and pelvis and radiates into the lower back and down the thighs.

Diseases that attack the sacroiliac can traumatize the joint and make it unstable. The most common include ankylosing spondylitis and rheumatoid arthritis. Extreme degeneration of the sacroiliac joint is rare, but may result in micro or macro instability of the joint structure.

Sacroiliac (SI) joint pain radiates deep into the buttock and lower back. The symptoms typically include a dull ache localized to one side that worsens with activity and prolonged positions. The pain may also extend down the leg similar to sciatica.

Hypermobility of the SI joint describes too much movement, which can lead to instability and pain in the lower back and hip that may radiate, or spread. An irritated SI joint can lead to inflammation in the joint, a condition known as sacroiliitis.

Dysfunction in the sacroiliac joint is thought to cause low back pain and/or leg pain. The leg pain can be particularly difficult and may feel similar to sciatica or pain caused by a lumbar disc herniation.

Explore the causes, symptoms, and advanced treatments for sacroiliac joint pain, including physical therapy for muscles affected by SI joint dysfunction.
