title: Perinatal hip assessment in very low birth weight infants.
abstract: Fifty healthy low birth weight infants (less than 1500 g) without risk factors for congenital hip dysplasia (CHD) were examined by ultrasonography (100 hips) at 40 weeks corrected age and controlled at 3 months postnatal age. Sonographic assessment was performed using the classification of Graf. A physiological delay of hip maturation was observed in 10% of the patients (type IIa). At follow-up all of them had normal hip morphology without any pathological finding. Our results suggest that prematurity alone should not be considered a risk factor for CHD.
