Triple prevention of congenital dislocation of the hip (CDH) consists of screening and earliest treatment in newborns, universal wide diapering in all presumably healthy hips, and repeated screening and early treatment in infants. Preventive activity proved to be decisively stimulated by introduction of “baby packages,” containing equipment for wide diapering, which are being distributed to every newborn free of charge. Since the introduction of baby packages, prevalence of CDH dropped from 1.3 to 0.7% despite incomplete distribution. Likewise, incidence of surgery for CDH decreased sevenfold.
