[Real-time sonography of the infant hip joint in the early diagnosis of congenital hip dysplasia].

The ultrasonic examination of infant hip joint means a great advantage in early diagnosis of congenital hip dysplasia. The sonographic type classification by Graf enables the experienced examiner to make up a differentiated diagnostic-therapeutic concept as early as possible. Therapeutic omissions just as well as exaggerated therapeutic measures can be avoided. Consequently the prognosis of hip joint dysplasia is considerably improved by ultrasonic examination of new-born hip joints.
