Sacroiliac Joint Pain (SI Joint Dysfunction)
It is a common cause lower back and/or leg pain.
Incidence:
It is estimated that the sacroiliac joint is responsible for 15% to 30% of lower back pain cases.
Sacroiliac joint dysfunction is more common in young and middle-aged women. Women who are pregnant or have recently given birth.
Anatomy:
The sacroiliac joint connects the hip bones (iliac crests) to the sacrum, the triangular bone between the lumbar spine and the tailbone (coccyx). The sacroiliac joint typically has little motion.
The primary mechanisms of SI joint dysfunction include:
Too much movement (hypermobility or instability) in the sacroiliac joint can cause the pelvis to feel unstable and lead to pain
Too little movement (hypomobility or fixation) can cause muscle tension, pain, and may inhibit mobility.
sacroiliitis (Inflammation of the sacroiliac joint)
Symptoms experienced with sacroiliac joint dysfunction commonly include:
• Lower back pain that feels dull, aching, and can range from mild to severe.
• Pain that spreads to the hips, buttocks, and/or groin.
• Sciatic-like pain in the buttocks and/or backs of the thighs.
• Worsened pain when putting added pressure on the sacroiliac joint, such as climbing stairs, running or jogging, and lying or putting weight on one side.
• Instability in the pelvis and/or lower back.
Diagnosis:
A diagnosis is usually arrived at through a physical examination and/or an injection. Imaging, like MRI and CT scan can help in the diagnosis.
The gold standard method for diagnosing the SI joint as the pain source is an injection test.
