[Histologic and echographic correlations of the hip in newborn infants]

Abstract

140 hips of fetuses have been studied using the Graf technique for morphological descriptions, the Harcke technique for dynamic studies. Then the hips were transected following the same plane as for sonography. The authors established that there was a significant relation between the progressive dysplasia of the acetabular roof and the sonographic morphological studies. The relation with the dynamic studies was less marked on cadavers studied shortly after delivery. The authors concluded that hyperpressure on the femoral head during the three last months of the pregnancy seems to be an important causal factor.
