OBJECTIVES: The risk of subsequent hip fracture is increased in presence of previous hip fracture. The most of the secondary hip fractures occur within the first 3 years after the initial hip fracture. The aim of our nationwide retrospective observational cohort study was to reveal the significance of demographic and clinical factors on time until subsequent hip fracture. METHODS: Patients aged 60 and over treated with primary femoral neck fractures in the year 2000 and suffered from contralateral hip fracture between 01 January 2000 and 31 December 2008 were selected from the database of the Hungarian National Health Insurance Fund. Patients’ data concerning their age, gender, place of living, type of primary fracture, comorbid medical diseases, surgical intervention for primary fracture and hospital providing treatment for primary hip fracture were evaluated. Multinominal logistic regression were used to analyse associations between prognostic factors and the time (<12 months, 12-24 months, 24-36 months, 36-48 months, 48-60 months, >60 months) until secondary fracture.
