Sacroiliac (SI) Joint Pain

The sacroiliac joint connects the last segment of the spine, the sacrum, to the pelvis. The integrity of the sacroiliac joint depends on strong ligaments that encase and cover the joint.  These ligaments compress and stabilize the joint.

 

 

 

Causes

Causes of sacroiliac joint disorders can be split into five categories:

  • Traumatic (lifting, fall, accident)
  • Biomechanical (leg length discrepancy, prior lumbar fusion)
  • Hormonal (pregnancy / childbirth)
  • Inflammatory joint disease (sacroiliitis)
  • Degeneration (age related wear and tear)

Symptoms

The most common symptom of sacroiliac joint disorders is pain in the lower back, buttock and legs. This can present as sciatica like symptoms:
