877例髋部骨折患者发病情况及其流行病学特征分析

Epidemiological features of 877 cases with hip fraction

目的 分析髋部骨折患者发病情况及其流行病学分布特征.方法 调查杭州市2012年1-12月所有省市级医院收治的髋部骨折患者临床资料,统计分析髋部骨折患者的性别、年龄、骨折部位和骨折诱因等相关数据.结果 共纳入研究髋部骨折患者877例,其中男性516例（58.84％）,女性361例（41.16％）;年龄（62.1±11.2）岁;髋部骨折患病率为10.0/10万,男性为11.2/10万,女性为8.8/10万,男性患病率明显高于女性,差异有统计学意义（f=4.281,P=0.033）.髋部骨折患者数量居前3位的年龄段分别为71～ 82岁（344例,39.22％）、61～70岁（196例,22.35％）和51 ～ 60岁（185例,占21.09％）.患者中股骨颈骨折显著多于股骨粗隆间骨折,差异有统计学意义（x2=21.423,P＜0.001）;男性发病构成比高于女性,差异有统计学意义（分别为x2=12.816,P＜0.001;f=13.773,P＜0.001）.造成髋部骨折前3位的因素分别为跌倒、坠落和车祸,其构成比分别为64.88％、20.07％和10.49％.结论 年龄是发生髋部骨折的重要因素.老年人群髋部骨折以股骨颈骨折为主,多以跌倒引发.

Objective To analyze the epidemiological features of hip fraction,and to improve the intervention program on this disease.Methods To investigate the clinical data of the patients with hip fraction who were treated at local hospitals,from Jan.to Dec.,2012.Information regarding sex,age,site and cause of the fracture was analyzed.Results 877 cases were treated at the local hospitals; including 516 males （58.84%） and 361 females （41.16%）.The overall incidence of hip fraction was 10.0/100 000,with 11.2/100 000 in males and 8.8/100 000 in females.The incidence was higher in males than that in females （x2=4.281,P=0.033）.Age distribution of the patients was：344 cases in age 71-82 （39.22%）,196 cases in age 61-70 （22.35%） and 185 cases in age 51-60 （21.09%）.Transcervical fracture appeared more than intertrochanter fracture of femur （x2=21.423,P〈0.001）,with males more than females in both fractures on femur （x2=12.816,P〈0.001 ; x2=13.773,P〈0.001）.The top 3 factors causing hip fractions would contain tumble （64.88%）,falling （20.07%） and traffic accident （10.49%）.Conclusion Incidence of hip fraction would increase with age with tumble as the major cause to it.
