Purpose: A retrospective study was conducted to examine the current trend in incidence rates of hip fractures among patients aged 50 years and older in Korea.
Materials and Methods: A retrospective study was conducted using data on the population, collected by Statistics Korea within the different gender and age groups in total population of Korea from 2007 to 2012. The International Classification of Diseases-10 classification method from the Health Insurance Review and Assessment Service was used to investigate the number of patients with hip fractures, and determine the crude incidence rate (CR) and the age-adjusted incidence rate (AR) for comparison.
Results: The CR of hip fractures for patients aged 50 years and older was 178 per 100,000 for men and 350 per 100,000 for women in 2007. In 2012, the CR was 194 per 100,000 for men, and 418 per 100,000 for women. The AR was 197 per 100,000 for men and 281 per 100,000 for women in 2007. In 2012, the AR was 206 per 100,000 for men, and 310 per 100,000 for women. During the observation period, the AR and the CR of hip fractures showed a statistically significant increase. However, the increasing trend has been slowing since its peak in 2010. Comparison of the AR of men and women, showed statistical significance only for women.
Conclusion: In Korea, the incidence of hip fractures increased significantly from 2007 to 2012. The AR showed statistical significance only for women and the increasing trend is slowing down from 2010.
