Cho, Kwak, Cho, Suh, and Lee: Epidemiology of Hip Fractures

Abstract

An epidemiologic study of hip fracture was done for 106 patients treated in six general hospitals and seven orthopaedic Clinics in Ulasn City and County from January 1990 to December 1991. The demographic informations from the 850,000 population in Ulasn City and County were related to factors such as patients age and sex, urban or rural community, the location of, fracture, and Singh Index. The results were also compared with those of other countries in the literatures. 1. The average age was 61.8 (SD 19.4). The age-specific incidence rate was 52.9 per 100,000 per year (men, 40.1; women, 57.2), which rate was higher than that in East-South Asia but lower than those in Europe and United States. 2. The crude incidence after the age of 60 was 63.2% in both sexes and 83.5% in women. The men-to-women ratio of the age-specific incidence rate was 96.2: 76.6 in the sixties, 151.1: 276.4 in the seventies and 172.4: 303.3 in the eighties. 3. The fracture occured most commonly at home (56.9%). In male below the age of 50, however, it occured most commonly during working. 4. The cause of injury was usually slip-down in females (77.9%), whereas the incidence by fall down was relatively high in males. 5. The cervical-to-trochanteric ratio in level of fracture was 1.6: 1 (21.8: 35.4) in women but not a lot of in men (18.4: 21.6). 6. The age-specific incidence rate was 58.5 per 100,000 per year in Ulsan City and 45.9 in Ulsan County (the urban-to-rural ratio; 1,3: 1). 7. The Singh Index was closely correlated with aging (correlation coefficient; -0.6741), but not with the location of fracture. The mean value of the Index after the age of 60 was 3.3 and the patients with the Index below 3 were 1.34 times more than those above.
