Abstract:

Developmental hip dysplasia（DDH）is a common hip disease in infants and children. The early diagnosis of DDH is very important. Previously, the basis of the diagnosis of DDH was from physical examination and AP roentgenograms. The diagnostic rate of physical examination is very low. And the conventional X-ray provides limited information, because the hip of infant is build up with vast cartilage, which nonvisualized in X-ray. Numerous infants and children were misdiagnosed or missed diagnosis. In recent years, more and more scholars both here and abroad pay attention to these facts. It is ultrasonic examination widely used, that effectively improve the diagnostic accuracy. Freshly, the research and application of MRI is developing in the diagnosis of DDH. In this article we reviewed the research progress and using value about physical examination and imaging findings on DDH.
