The incidence of EOS is approximately four-times higher in Europe compared with USA (1–2 per 10000 people). The Edinburgh survey by McMaster demonstrated an incidence of 50% of all patients with idiopathic scoliosis had infantile curves.[7] By contrast, a survey from Boston with a population from a similar genetic stock showed an incidence of 0.5%.[8] Scott and Morgan compared the incidence between England and USA and found the incidence of scoliosis before the age of 2 years was significantly higher in England.[9] This difference led to speculations regarding the presence of a triggering factor in the environment that may be beneficial to babies in the USA.

The majority of the curves (75–90%) tend to be left-sided in contrast to the right-sided curve patterns in late-onset idiopathic curves. Males account for 60% of the cases of EOS; 10% of cases progress to a severe and disabling condition.[10] The differences in gender and curve lateralization do not make any difference to the management.
