[Incidence and development of noticeable hip findings (the dysplasia complex) in newborn and young infants. Additional statistical analysis of the findings].
Early signs of hip dysplasia in 7120 children (in the neonatal period asymmetry of the gluteal folds, Ortolani snap phenomenon and restricted abduction; subsequently, at about 6 weeks, asymmetry of the gluteal folds and restricted abduction) were statistically analyzed with regard to simultaneous occurrence and their prognostic value in confirming a hip dysplasia. The findings at 6 weeks were found to be more serious. Almost no significance can be attached to an isolated finding in the period following birth. Since the study covered several clinics, it was possible to compare findings from individual centers. It was found that they fell into four groups with different diagnostic preferences, despite the agreed uniform examination technique. Thus, almost all of the positive Ortolani findings were diagnosed at two of the 20 clinics taking part in the study. In the overall comparison the group of clinics which relied almost exclusively on asymmetry of the gluteal folds had the least prognostic success. The clinics with a higher proportion of positive Ortolani findings had better prognosis results, though the incidence of dysplasias was not increased.
