[Echography of the hip in dislocation disease in newborns and infants]. / Studio dell'ecografia delle anche nella malattia lussante del neonato e del lattante.

At present, ultrasounds represent the most reliable investigation with images for early C.H.D. diagnosis. This test is innocuous so it can be repeated and furnishes, especially in the first months of life, all those informations the traditional radiology cannot give us. In this work the authors report a clinical and ultrasonographic study of 1116 children (2232 hips); 127 of these were newborns and they have been followed-up from their birth to 7th month of life with ultrasound test at 1.-3.-5.-7. month of life. U.S. investigation has proved itself very sensitive and specific.
