To highlight the utility of MR imaging in the evaluation of developmental dysplasia of the hip following surgical reduction To illustrate the imaging appearances of the concentrically and non-concentrically reduced hip, including obstacles to and complications of reduction

Background and rationale for MR imaging Imaging technique Examination timing and anesthesia Imaging parameters Motion artifact/repetitive acquisition Image interpretation Concentric reduction Ossified vs. non-ossified capital femoral epiphyses Postsurgical changes with closed and open reduction Osteotomy hardware Obstacles to concentric reduction Inverted labrum and limbus formation Hyperterophy of the ligamentum teres/tranverse acetabular ligament Enlarged pulvinar Complications Persistent dislocation Capital femoral epiphyseal contusion Osteonecrosis Contrast administration and epiphyseal perfusion Incidental pelvic pathology Clinical and imaging follow-up Conclusions
