2010至2011年我国华北和华东地区老年Colles骨折患者的流行病学特征分析

Epidemiological comparison of Colles fractures in the elderly between northern and eastern China from 2010 to 2011

目的对比分析中国华北地区和华东地区2010年1月至2011年12月老年Colles骨折患者的流行病学特点。方法利用医学影像计算机存档与传输系统(PACS)及病案查询系统收集2010年1月至2011年12月华北地区和华东地区39家医院诊治的老年Colles骨折患者资料。将华北地区18家医院资料定义为华北组,华东地区21家医院资料定义为华东组,对比分析两组患者性别、年龄、侧别等。结果共收集老年Colles骨折2 610例,其中男性466例(17.85%),女性2 144例(82.15%),男女比为1∶4.60;年龄中位数为70岁;左侧(1 372例,52.57%)多于右侧(1 238例,47.43%)。华北组1 777例,其中男性349例,女性1 428例,男女比为1∶4.09;华东组833例,其中男性117例,女性716例,男女比为1∶6.12,差异有统计学意义(χ~2=12.102,P=0.001)。华北组和华东组年龄中位数分别为69岁和71岁,差异有统计学意义(Z=-4.372,P<0.001)。华北组和华东组均为60~65岁年龄段构成比最高,分别占35.34%(628/1 777)和29.05%(242/833),两组60~65岁、81~85岁和≥86岁3个年龄段构成比差异有统计学意义(χ~2=10.094,χ~2=5.028,χ~2=24.885,P<0.05),其他年龄段构成比差异无统计学意义。华北组和华东组老年Colles骨折均为左侧多于右侧,差异无统计学意义。结论老年Colles骨折女性多于男性,左侧多于右侧,60~65岁年龄段构成比最高,约占1/3。与华东地区相比,华北地区老年Colles骨折患者年龄低,男女比高,60~65岁年龄段构成比高,81~85岁和≥86岁年龄段构成比低。

Objective To compare and analyze the epidemiological features of Colles fractures inthe elderly between Northern and Eastern areas of China from January 2010 to December 2011. MethodsData of Colles fractures treated between January 2010 to December 2011 in 39 hospitals in northern andeastern China were collected through the PACS system and case reports checking system. Data of 18hospitals in northern China were classified as group northern, while data of 21 hospitals in eastern Chinawere classified as group eastern. Gender, age and side between two groups were compared. Results A totalof 2,610 Colles fractures in the elderly were divided into group northern （1,777 cases） and group eastern（833 cases）. There were 466 males （17.85%） and 2,144 females （82.15%）, with a male/female ratio of 14.60and a median age of 70 years. Left fractures （1,372 cases, 52.57%） were more than the right side （1,238cases, 47.43%）. There were 349 males and 1,428 females in group northern （M/F=1：4.09）, and 117 malesand 716 females in group eastern （M/F=1：6.12, c2=12.102, P=0.001）. The median age of the two groupswere 69 years and 71 years, respectively, with a statistically significant difference （Z=-4.372, P〈0.001）. Thepredominant age group in two groups was from 60 to 65 years, accounting for 35.34% （628/1,777） and29.05% （242/833）, respectively. The age distribution had significant differences in patients aged 60-65 years,81-85 years and ≥86 years between the two groups （c2=10.094, c2=5.028, c2=24.885, P〈0.05）. There wereno significant differences of other age groups between group northern and group eastern. There were moreleft fractures than right side in group northern and group eastern. Conclusions Colles fractures in elderlywere most seen in females and left side. The predominant age group was from 60 to 65 years, accounting forabout 1/3 of all injuries. Compared with eastern China, the patients were younger. The male/female ratio andproportion of 60 to 65 years were higher, while the proportion of 81-85 years and ≥86 years was lower.
