Hip fracture incidence is rising dramatically in New Zealand, particularly among the elderly. Projections indicate a doubling of hip fractures by 2011, with the very elderly being most affected.

Area of Science:

  • Gerontology
  • Orthopedic Surgery
  • Public Health

Background:

  • Studies from the UK and Sweden indicate a significant increase in hip fractures.
  • This trend suggests a potential rise in hip fractures in other developed nations.

Purpose of the Study:

  • To investigate the incidence of hip fractures in New Zealand.
  • To analyze trends in hip fractures among the elderly population over 38 years.
  • To project future hip fracture numbers and identify high-risk demographics.

Main Methods:

  • Retrospective review of elderly patients (over 65 years) admitted to New Zealand public hospitals over 38 years.
  • Analysis of age-specific fracture rates and population demographics.
  • Weighted regression analysis for future fracture prediction.

Main Results:

  • A disproportionate increase in hip fractures was observed in individuals over 75 years compared to population growth.
  • Women over 85 years represented the highest-risk group.
  • The proportion of females over 85 increased from 17% in 1950 to 40% by 1987.
  • Projected hip fractures to more than double by 2011.
  • The proportion of the very elderly (85+) is predicted to increase from 40% to 65% by 2011.

Conclusions:

  • New Zealand is experiencing a significant rise in hip fractures, mirroring international trends.
  • The aging population, especially the very elderly (85+), is driving this increase.
  • Urgent public health strategies are needed to address the growing burden of hip fractures.
