Classification of hip joint dysplasia by means of sonography.

Our report relates to our experimental investigations and clinical experience gained with the sonography of infant hips. On the basis of over 3,000 sonograms we were able to carry out a standardization of dysplasia forms from the sonographic point of view. It is possible to recognize disturbed hip maturation already after birth and to continuously control the further development. New sonographic findings and details permit to take up a more differentiated therapy as applied so far.
