Abstract

This study analyzes the incidence of subsequent hip fractures and its risk factors in the northwestern region of Korea. We analyzed hip fracture patients who visited any of the 5 teaching hospitals in the Bucheon and Incheon area from January 2000 to December 2010. Medical records were reviewed and presence of subsequent hip fractures, alcohol history, marital status, live in solitude, dementia, dizziness, American society of anesthesiologists score, osteoporosis treatment after fracture, body mass index (BMI) and initial bone mineral density were analyzed. The average follow-up period was 12 months (range 1-130 months). A total of 2,546 patients (women 1,770, men 776) who had experienced hip fractures were included. Of these, subsequent hip fractures were found in 233 patients (9.2%) (women 187, men 46). Mean age at the time of the first fracture was 79.2 yr old (range 50-100 yr). The average interval between the first fracture and the subsequent hip fractures was 30.2 months (range 4 days-154 months). In this large-scale, retrospective, multicenter study, overall incidence of subsequent hip fractures is 9.2%. Independent risk factors of subsequent fracture are women, BMI<22 kg/m2, and being unmarried.
