Background The Medical Research Council Working Party on Congenital Dislocation of the Hip have reported an ascertainment-adjusted incidence of a first operative procedure for congenital dislocation of the hip (CDH) of 0.78 per 1000 livebirths, which is similar to the incidence of CDH before the start of the UK screening programme. The report showed that CDH had not been detected by routine screening before age 3 months in 70% of children reported to the national orthopaedic surveillance scheme. This report raised concerns about the merit of screening at birth for CDH. We aimed to find out the incidence of an operative procedure for CDH in the first 5 years of life among children bom in South Australia between 1988 and 1993, and the proportion of these patients that were detected at age 3 months or older. Methods The state's database for inpatient separations between January, 1988, and April, 1998 was searched. Case records were examined for the age and circumstances of diagnosis, and type of operative procedures. Prevalence rates of CDH were obtained from the South Australian Birth Defects Register, which receives notifications from a statutory perinatal data collection of birth defects detected at birth and subsequent voluntary notifications for children up to age 5 years.
