This study analyses the incidence of subsequent hip fractures and its risk factors in the northwestern region of Korea. We analysed 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 (ASA) score, osteoporosis treatment after fracture, body mass index (BMI) and initial bone mineral density (BMD) were analysed. The average follow-up period was 12 months (range: 1-130 months). A total of 2546 patients (female: 1770, male: 776) who had experienced hip fractures were included. Of these, subsequent hip fractures were found in 233 patients (9.2%) (female: 187, male: 46). Mean age at the time of the first fracture was 79.2 years old (range: 50-100 years). 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 female gender, BMI<22kg/m2, and being unmarried.
