[Epidemiologic characteristics of congenital hip dysplasia in a Chilean population].
The results of a retrospective study on 97 cases of congenital hip dysplasia and 100 controls matched by sex and birth weight are presented. A female: male ratio of 6.5:1 and a higher frequency (68%) of bilateral involvement were found. Statistically significant differences were found for a positive family history of congenital hip dysplasia and breech presentation and 23% cases were not clinically suspected before hip x-ray. Better screening methods by early ultrasonography and radiologic examination are proposed.
