[Ultrasonic and anatomical correlation of the normal hip in the newborn infant]

Ultrasound studies were made on the cadavers of seven normal new-born foetuses. The sonographic images obtained were compared with anatomical sections made in corresponding planes. An accurate analysis of the anatomy of the cartilaginous acetabular roof and labrum in these hips confirmed the accuracy of ultrasonography. Ultrasonography has made it possible to resolve certain doubts about the radiographic examination of infants between birth and the third month.
