Objective To analyze the characteristics of age, sex and causes of hip fractures in the elderly patients with a view of developing a preventive protocol. Methods Enrolled in this study were the elderly patients treated for hip fractures at the Trauma Emergency Department of Beijing Jishuitan Hospital from September 2018 to December 2018. All the selected patients were investigated by a questionnaire covering age, gender, diagnosis, time and month of the fracture, external force, location of fracture, and whether the fall occurred in the bathroom at night. SPSS statistics 22.0 was used for data analysis. The data were analyzed by t-test, analysis of variance, and χ² test. Results A total of 414 patients were included in the analysis, with an average age being (80.7±7.7) years, the highest proportion (50.2%) of age group being of 80-89 years old, and female being significantly more than male. The patients with femoral neck fracture were more than those with intertrochanteric fracture, the former being younger than the latter and the difference being statistically significant(P<0.05). More patients were injured during the day than at night, and those injured during the day were younger than those injured at night, but with no significant difference(P>0.05). Fractures incurred at falls at home featured prominently, and using bathroom at night was the main cause of fractures at night. The older the patient, the more obvious the characteristics (P<0.05). Conclusion Hip fractures in the elderly have their own characteristics in the respects of age, gender, and cause, and prevention protocol can be proposed accordingly to reduce their occurrence.
