Area of Science:

  • Pediatric Orthopaedics
  • Epidemiology
  • Nutritional Science

Background:

  • Perthes' disease is a childhood hip disorder with suspected nutritional links.
  • Geographical variations in incidence suggest environmental or nutritional factors.
  • Previous studies indicate a higher prevalence in urban settings.

Purpose of the Study:

  • To investigate geographical variations in Perthes' disease incidence in the Yorkshire region.
  • To explore potential correlations between incidence and environmental factors.
  • To identify areas with unusually low or high disease occurrence.

Main Methods:

  • Prospective data collection of new Perthes' disease cases by orthopaedic surgeons.
  • Two-year study period across the Yorkshire region.
  • Analysis of incidence rates based on geographical location, considering urban-rural and social class factors.

Main Results:

  • Significant geographical disparities in Perthes' disease incidence were observed.
  • Incidence could not be attributed to urban-rural or social class differences.
  • A notable absence of cases was recorded in a large eastern region characterized by high-grade farming land and low infant mortality.

Conclusions:

  • Geographical variations in Perthes' disease incidence are significant and not explained by common demographic factors.
  • Environmental factors, potentially linked to agricultural land use and low infant mortality, may play a role in disease aetiology.
  • Further research into nutritional and environmental influences is warranted to understand Perthes' disease development.
