title: [Sonography of the hip in underweight premature infants].
abstract: In a prospective study 120 hips of preterm babies below 2,000 g were investigated by ultrasound studies in order to determine the distribution of the types according to Graf's classification. Compared with unselected newborns, preterm babies show a significantly higher incidence of ultrasound types Ib and IIa. The distribution of the ultrasound types of the hips of both groups is compared.
