Anatomy of the sacroiliac joints in children and adolescents by computed tomography

Abstract

Abstract Background Diagnosing sacroiliitis by magnetic resonance imaging (MRI) in children/adolescents can be difficult due to the growth-related changes. This study analyzed the normal osseous anatomy of the sacroiliac joints (SIJ) in a juvenile population using computed tomography (CT). Methods The anatomy of the SIJ was retrospectively analyzed in 124 trauma patients aged 9 months – 3 mm occurred in 21 children/adolescents (17%) located to both the iliac and sacral joint facets. Conclusions Normal osseous SIJ structures in children and adolescents vary considerably. Attention to these normal anatomical structures during growth may help to avoid false positive findings by MRI.
