分析河北省老年股骨转子间骨折的流行病学特征。

收集河北省5家医院自2010年1月至2011年12月间就诊的骨折患者的基本资料和数字化影像资料进行数据分析，筛选出60岁以上发生股骨转子间骨折的老年患者，记录并比较其性别、年龄、AO分型等数据，分析两年间河北地区老年股骨转子间骨折的流行病学特征。

共收集老年股骨转子间骨折患者2 142例。其中男性984例（45.9%）、女性1 158例（54.1%），男女比例为1∶1.18；左侧骨折1 117例（52.1%）、右侧骨折1 025例（47.9%）。年龄61~99岁，平均年龄（65±8）岁，各年龄段骨折中以71~80岁组所占比例最高（45.0%），按照AO分型，31-A2型所占比例最高（59.1%）；31-A3型所占比例最低（12.3%）。

河北省老年股骨转子间骨折占同期全部股骨转子间骨折的67.7%，占同期60岁以上所有骨折患者的13.4%。女性普遍多于男性。71~80岁年龄组所占比例最高；31-A2型骨折所占比例最高。

To investigate epidemiological characteristics of femoral intertrochanteric fractures in elderly patients in Hebei.

The digital radiography imagedata and basic information of patients above 60 years with hip fractures from 2010 to 2011 were analyzed retrospectively in 5 hospitals of Hebei. All data including patients' gender, age, and AO types were abstracted and analyzed to investigate the epidemiologic characteristics of femoral intertrochanteric fracture occurring during this time in this district.

A total of 2,142 femoral intertrochanteric fracture with age above 60 years old were included, 984 (45.9%) males, 1,158 (54.1%) females (M∶F=1∶1.18). Fractures involving left side were slightly more than the right (1,117/1,025). The fracture was most common in age of 71-80 years group (45.0%) with the mean age of (65.0±7.9) years. By AO classification, type 31-A2 was the most common fracture type (59.1%), with type 31-C3 as the least common type (12.3%).

In elderly patients, femoral intertrochanteric fractures accounts for 67.7% of femoral intertrochanteric fractures in all ages, and 13.4% of all fractures in hebei, female are more prone to hip fractures than male, and the most peak age is 71-80 years. 31-A2 is the most common fractures type.
