Post-closed Reduction Perfusion Magnetic Resonance Imaging as a Predictor of Avascular Necrosis in Developmental Hip Dysplasia

In addition to accurate anatomical assessment of a closed reduction in DDH, gadolinium-enhanced MRI provides information about femoral head perfusion that may be predictive for future AVN. At present, it is premature to use the perfusion information for routine clinical use. However, it opens the door to studies looking at repositioning or alternative reduction methods that may reduce the risk of AVN in this higher risk group.
