Causes
Common Causes
- Injury or Trauma: Falls, accidents, or sudden movements affecting the joint
- Arthritis: Wear and tear or inflammation of the SI joint
- Pregnancy-Related Changes: Hormonal and biomechanical changes that loosen ligaments
- Degenerative Changes: Age-related joint wear over time
- Postural or Mechanical Issues: Abnormal gait or uneven leg length that strains the joint
SYMPTOMS
Symptoms to Watch For
- Pain in the lower back, hips, or buttocks
- Discomfort radiating down the legs
- Sharp, aching, or stabbing sensations in the affected area
- Pain that worsens with standing, walking, sitting, or climbing stairs
- Stiffness or reduced range of motion in the hips or lower back
Diagnosis
How It’s Diagnosed
Diagnosis typically involves a physical exam to evaluate joint motion, tenderness, and posture. Doctors may review your medical history and order imaging tests such as X-rays or MRI to rule out other sources of pain. Special maneuvers or injections may sometimes be used to confirm SI joint involvement.
Treatment Options
Non‑surgical / Lifestyle Approaches:
- Physical therapy and gentle exercises to improve strength and mobility
- Anti-inflammatory medications for pain relief
- Activity modification and posture improvement
- Supportive belts or braces to stabilize the joint
Advanced Treatments:
- Corticosteroid injections to reduce inflammation and pain
- Rarely, surgical procedures to fuse or stabilize the SI joint
