SI joint involvement is the sine qua non for a definite diagnosis. Diagnosis is very involved, and includes: chronic low back pain, buttock pain, sacroiliitis, family history, psoriasis, inflammatory bowel disease or arthritis followed in ≤ 1 month with urethritis, cervicitis or acute diarrhea, an enthesopathy, and family history, and positive X-rays.
