[Status quo of screening for hip dysplasia]

Since the first description of the ultrasound examination of the infant hip by Graf in 1980 this technique has impressively demonstrated that it lives up to its promise very well. In the implementation of hip ultrasound in the German pediatric guidelines it was hoped that it would improve the sensitivity and specificity of the early detection of dislocated and dysplastic joints in comparison to a general clinical hip screening. Furthermore, it has been repeatedly shown that general newborn hip ultrasound screening according to Graf can significantly reduce not only the treatment rate but also the invasiveness. Consequentially, the cost of treatment as well as the rate of late presenting developmental dysplasia of the hip (DDH) can also be significantly reduced. Despite those proven merits the meaningfulness of general hip ultrasound screening in infancy is still questioned, especially in the Anglo-American world. This article reviews how this misconception came about.
