中国中西部地区2010至2011年60岁以上股骨颈骨折流行病学对比

Epidemiological analysis of femoral neck fractures in patients over 60 years between middle and west areas of China from 2010 to 2011

目的对比分析我国中、西部地区2010至2012年60岁以上股骨颈骨折的流行病学特点。方法利用医学影像计算机存档与传输系统及病案查询系统收集2010年1月至2011年12月中、西部地区44家医院诊治的股骨颈骨折资料。将安徽省、河南省、吉林省、山西省、湖北省、湖南省、黑龙江省定为中部组;将新疆维吾尔自治区、四川省、重庆市、甘肃省、广西贵族自治区、贵州省、西藏自治区、内蒙古自治区、宁夏回族自治区、青海省、陕西省、云南省定为西部组。对比两组患者性别、年龄、骨折分型及侧别构成等。结果共收集60岁以上股骨颈骨折3 683例,中部组2 067例,男女比为1∶1.98;西部组1 616例,男女比为1∶1.76。中部地区76~80岁年龄段构成比最高,西部地区71~75岁年龄段构成比最高。两组均以31B2型骨折患者构成比最高,中部组51.1%(1 056/2 067),西部组48.3%(781/1 616);31B1型构成比最低,中部组21.5%(444/2 067),西部组19.7%(318/1 616)。中部左侧1 077例(52.1%),右侧990例(47.9%);西部组左侧797例(49.3%),右侧819例(50.7%)。结论老年股骨颈骨折以女性多见,中部地区以76~80岁年龄段构成比最高,西部地区以71~75岁年龄段构成比最高;中、西部均以85岁以上年龄段构成比最低。两地区31B2型骨折居多,中部地区31B1型构成比较西部高,31B3型较西部低;中部地区左侧股骨颈骨折多于右侧,西部地区右侧多于左侧。

Objective To compare and analyze the epidemiological features of patients over 60 years with femoral neck fractures between middle and west areas of Chinafrom January 2010 to December2011. Methods Data of patients over 60 years with femoral neck fractures treated from January 2010 to December 2011 in 44 hospitals in middle and west areas of China were collected. Patients were divided into middle group(Anhui province, Henan province, Jilin province, Hunan province, Heilongjiang province,Hubei province, Shanxi Province) and west group(The Xinjiang Uygur Autonomous Region, Sichuan province, Chongqing Municipality, Gansu province, Guangxi Zhuang Autonomous Region, Guizhou province, Tibet Autonomous Region, Ningxia Hui Autonomous Region, Qinghai province, Shanxi province,Yunan province). The gender, age, sides and fracture classification between two groups were compared and analyzed. Results A total of 3,683 cases were included, 2,067 cases in the middle group with a M/F ratio of1:1.98 and 1,616 cases in the western group(M/F=1:1.76). Age distribution showed that the peak range was76-80 years in middle areas and 71-75 years in western group with proportion of 24.4% and 23.5%,respectively. The high risk fracture type is 31 B2 in both groups, with the proportion of 51.1%(1,056/2,067)and 48.3%(781/1,616), while the valley range was 31 B1 with proportion of 21.5%(444/2,067) and 19.7%(318/1,616) respectively. There were 1,077(52.1%) in left and 990(47.9%) in right in middle group while797(49.3%) and 819(50.7%) in western group. Conclusions The peak age is 76-80 years in middle areas and71-75 years in west areas, the valley range was over 85 years in both groups. The high risk fracture type is 31 B2.31 B1 in middle areas was higher than that in west areas and the proportion of 31 B3 in middle areas was lower than western group. The middle areas had more left-side fractures and more right-side fractures in west areas.
