Summary
We determined the number and incidence of hip fractures in Tangshan, China, in 2010. Compared with data we reported in Tangshan from 1994, the crude and age-specific incidence increased significantly for both sexes, especially in women. Strategies are needed for effective fracture prevention in the future.
Introduction
The aims of the study were to determine the incidence of cervical and trochanteric fractures of the proximal femur in Tangshan, China, in 2010 and to compare the incidence with data from 1994.
Methods
The orthopedic departments of 15 hospitals in Tangshan were visited in 2010; the medical records and radiographs of patients who had sustained cervical and trochanteric fractures were reviewed. The absolute number of admissions was collated and the incidence rate per 100,000 person years was calculated, adjusted by different age ranges, and gender. We then calculated the age-standardized incidence in 2010 as compared with those from 1994.
Results
The population of Tangshan in 2010 was determined to be 3,075,382 (1,558,173 males; 1,517,209 females); there were 1,509 cervical and trochanteric fractures (in 745 males and 764 females). The overall incidence was 47.8 and 50.4 fractures per 100,000 per year for men and women, respectively. Females showed a higher fracture incidence than males in those aged 55 years and over. Comparing the 2010 data with the 1994 findings, the incidence increased by 85 % in men and by 306 % in women; age-specific increases were observed in all female and male groups (except the 55–59 years age group).
Conclusions
Compared with the results in 1994, the incidence of hip fracture has markedly increased in 2010 in Tangshan, China. It is necessary to implement a comprehensive policy for hip fracture prevention in our communities.
