- Twisting, bending, or moving in a way that triggers sacroiliac joint pain
- Infection of the joint
- Osteoarthritis of the joint, which is more common in older adults
- Trauma, such as an auto accident
- Stress fractures, which is common in athletes
- Inflammation of the joint, which can occur with ankylosing spondylitis
