Hip dysplasia – present in 4% of infants born alive, four times more often in girls.
We should also remember about so-called clinically silent hip dysplasia. It is important to conduct a good clinical and sonographic examination. It is not possible to carry out this examination too early, because a professional who conducts it, is aware of anatomical and clinical differences in hip joints between newborn babies and infants. Conducting the examination not early enough or interpreting the images incorrectly can have serious consequences. In Poland we use Graf method in sonography. In my practice, in case of doubts I additionally make use of other sonographic projections, i.e. Harcke, Dalström and Bocquet methods.
