Aims

We aimed to examine the true incidence of DDH in our area, and to investigate both known and unknown risk factors for the condition.

Methods

Data were prospectively recorded on all live births in the Exeter area from January 1998 to December 2008. The data included the baby's gestational age, sex, demographic details of parents, maternal age and parity, geographic and socioeconomic data, mode of presentation and delivery, and family history of DDH. Data were also collected prospectively on all treated cases of DDH (Graf 2c and above) for the same period. Using the population live birth data as controls, odds ratios (OR) and confidence intervals were calculated.
