Rheumatologist Questions Sacroiliac joint

Why does my son have sacroiliac joint pain?

My son is only 12 years old and his sacroiliac joint is swollen and causing him a lot of pain. He is also pretty active. I thought this was only an adult issue. What's causing his joint pain?

This is a very good question because on physical examination, we cannot feel the sacroiliac joint. We have indirect measures of assessing this on exam, but we really rely on imaging modalities to help determine if, in fact, the sacral iliac joint is involved. The most common disorders of the sacral iliac joints include a family of conditions called the spondyloarthropathy. This family includes conditions such as ankylosing, spondylitis, psoriatic, arthritis, reactive, arthritis, and arthritis related to underlying inflammatory bowel disease, such as Crohn's disease or ulcerative colitis. Importantly, there are pain, symptoms, and pain symptoms that do not directly relate to the sacral iliac joints. Therefore, my recommendation is for your son to have an evaluation to try to get to the bottom of this problem.
It could be because of an infection. He should see his doctor.
