Sacroiliitis Explained:
What You Need to Know

Does your job require prolonged sitting or heavy labour that involves repetitive lifting and bending? Do you feel pain in your lower back? While many people think it is sciatica, there can be another possible cause – Sacroiliitis.

What is Sacroiliitis?
The term sacroiliitis refers to inflammation of one or both SI (sacroiliac) joints. The sacroiliac joint is the area where the sacrum (base of spine) and pelvis connect, which plays an important role in transferring weight from the upper body to lower limbs and acts as a shock absorber.

Common Causes

  • Often associated with various forms of Arthritis, including ankylosing spondylitis, osteoarthritis
  • Pregnancy - A change in the biomechanical force in the lower back can increase the stress on this joint
  • Trauma – For example, falls or motor vehicle accident
  • In rare cases, certain infections can also lead to sacroiliitis

Signs and Symptoms

  • Dull, aching pain in the lower back, buttocks or hips is the most common symptom, which can radiate to one or both legs.
  • Decrease in range of motion/stiffness in the lower back
  • Symptoms can be aggravated by sitting for prolonged periods, standing on one leg or prolonged standing, or high-impact activities like running or jumping

Diagnosis
The sign sand symptoms can mimic lower back pain or sciatica; therefore a proper physical examination by a health care provider is needed to understand, which includes subjective and objective assessments of the affected area and determining the root cause behind this condition.
