OBJECTIVE

The purpose of this article is to review developmental dysplasia of the hip (DDH), a well-described entity previously evaluated with a standard multimodality imaging algorithm, typically consisting of ultrasound and radiography depending on patient age.

CONCLUSION

MRI is increasingly used because it is a noninvasive imaging modality that offers excellent anatomic detail, enabling the differentiation of ossified and unossified components of the hip. The radiologist should be aware of the increasing role of MRI and recognize the critical MRI findings of DDH.
