Abstract
The MRC Working Party (United Kingdom) on CDH recently reported an ascertainment adjusted incidence of a first operative procedure for CDH of 0.78 per 1,000 live births, similar to the incidence before the commencement of the U.K. Screening programme. It also found that 70% of cases had not been detected before 3 months of age.
South Australia has had a similar clinical screening programme since 1964. This study determined the incidence of an operative procedure for CDH in the first 5 years of life among children born in South Australia between 1988 – 1993 (118,379 live births in total) and the proportion detected after 3 months of age.
Of 47 children identified as having non-teratologic DDH and operative procedures, 24 were diagnosed before one month of age. Some required operative intervention beyond 3 months of age despite early diagnosis. Only 22 (46.8%) had been diagnosed at or after 3 months of age 18 of the 47 had an open reduction and/or osteotomy while the remainder had arthrograms, closed reductions and/or tenotomy
The prevalence of non-teratologic DDH was 7.7 per 1,000 live births. The incidence of surgery in the first 5 years of life was 0.40 per 1,000 live births and only 0.19 per 1,000 for those late diagnosed at or after 3 months.
These results demonstrate that a screening programme can be successful, contrary to the findings of the UK MRC Working Party.
