title: [Incidence and development of noticeable hip findings (a dysplasia complex) in newborn and young infants].
abstract: Among 5338 infants in a DFG (German Research Association) priority program for prospective examination of pregnant women and neonates, asymmetry of the gluteal folds was found in approx. 12%. However this is of little diagnostic value for early diagnosis of hip dysplasia/luxation. The number of cases of restricted abduction found was even lower: in the period following birth it was 3.4%, from the 3rd to the 14th week. 12.7%. Ortolani's sign, including slightly positive and uncertain findings, was positive in 3.0% of the neonates; a hip dysplasia/luxation was diagnosed in 2.4% of the infants. The high percentage of suspected cases diagnosed, at 12.6%, is indicative of excessive diagnosis, even though this figure may already contain some oblique-presentation hips. Moreover, all the data are rendered relative by the differences in emphasis made by the 20 clinics taking part in the study; as a result the actual state and hence the uncertainty of early diagnosis of a hip dysplasia in practice are faithfully reflected. The results are compared with corresponding figures published by Barlow from a study of 9289 children.
