Observations in children with congenital dislocation of the hip.

In 111 children who were diagnosed and treated for CDH, certain variables concerning their vital statistics, the laxity of their joints and circumstances at birth were recorded. It was observed that breech presentation, birth rank one and female preponderance are common traits in children with CHD, who also become taller and heavier than control children. Anomalies found at birth or later were more common among these children, in particular inguinal hernia. Also, joint laxity was more common in these children. An increased incidence of CDH was found among siblings.
