ObjectivesHip fractures associated with osteoporosis are indicative of high rates of both disability and mortality. The objective of this study was to analyze the risk factors for recurrent hip fractures following primary osteoporotic hip fracture surgery in older adult patients.MethodsA single-center, retrospective cohort study was conducted on 376 patients suffering from primary osteoporotic hip fractures from 1 January 2020 to 31 December 2021. Multivariate logistic regression was used to identify risk factors for recurrent hip fractures.ResultsThe study observed 376 patients over a period of three years. The incidence of recurrent hip fractures was 20.5% (77/376). Multiple logistic regression analysis revealed that age ≥ 85 years (odd ratios [OR] = 3.127, 95% confidence interval [CI] = 1.672-5.849, p p p = 0.012) were independent risk factors for recurrent hip fractures; antiosteoporosis drugs (OR = 0.243, 95%CI = 0.131-0.451, p p = 0.003) and serum albumin ≥ 35 g·L-1 (OR = 0.413, 95%CI = 0.194-0.881, p = 0.022) were independent protective factors for recurrent hip fractures. The receiver operating characteristic (ROC) curve demonstrated that the AUC was 0.802, the sensitivity was 77.8%, and the specificity was 75.5%. A significantly higher three-year mortality rate was observed among patients with recurrent hip fractures (26.0% vs. 15.4%, p = 0.029).ConclusionsOlder patients with advanced age, COPD and PD were at greater risk of recurrent hip fractures. Early nutrition intervention and antiosteoporosis drug therapy may decrease the incidence of recurrent hip fractures in older patients, thereby reducing mortality.
