| Objective To describe the characteristics of patients with proximal femoral fractures, spinal fractures and distal radial fractures over fifty-five years old and analyze their time-trend. Methods The search strategy was made by using ICD-10, this paper reviewed the information of inpatients, which were over 55 years old (inclusive) r, with three types of fractures: proximal femoral fractures, spinal fractures and distal radial fractures. This paper mainly described and analyzed their age, gender distribution and time tendency. Results The incidence of proximal femoral fractures increased with age(P<0.001), the occurrence of distal radius fractures and spinal fractures was the opposite to it, decreasing with age(P<0.001，P=1.29*10-35). The peak age of proximal femoral fractures increased, and it was between 80 and 85 years old in the past three years. The trend was the same between the male and the female. The peak age of distal radius fractures had also increased, and the latest peak was between 60 and 65 years old. The trend was the same for female, but the change in the male was not significant. The peak age of spinal fractures shifted over the year, but the trend was not significant. The overall was decreasing from 75 to 65 years old, in which male was between 75 and 79 years old changing to 60 and 64 years old, the female was from 70-75 years old to 65-70 years old, but the decrease was greater in the male. For the period of 2010 to 2018, The changes in the average sex ratio of the three types of fractures were: (female: male) proximal femoral fractures was 2.13:1-2.43:1, spinal fractures was 3.37:1-3.77:1, and distal radius fractureswas 3.76:1-4.96:1 respectively. Conclusion Attentions should be paid to the diagnosis and treatment of fractures in the elderly, especially in the proximal femur. The female osteopenia fracture still occupied the clinical dominant position, but the osteoporosis problem of middle-aged and elderly men could not be ignored. With its specific etiology, it is recommended to include it in the diagnosis and treatment guidelines. |
