Get StartedRisk factors
By Mayo Clinic staffThe following factors may increase your likelihood of getting the condition:
- A history of bone, joint or skin infections. Some people are more prone to infections, and an infection is one possible cause of sacroiliitis.
- Injury or trauma to your spine, pelvis or buttocks. Torn ligaments or trauma may create inflammation or infection of the sacroiliac joints.
- Urinary tract infection. This infection may spread from your urinary tract, which includes your kidneys, bladder and urethra, to your sacroiliac joints.
- Pregnancy. The pelvic bone's expansion to prepare for childbirth may inflame the area around your sacroiliac joints.
- Endocarditis. This infection of your heart's inner lining may spread to your sacroiliac joints.
- Illicit drug use. People who inject drugs may have a higher risk of developing sacroiliitis.
