2010年至2011年中国东部地区与西部地区成人髋臼骨折的流行病学对比分析

Epidemiological comparison of adult acetabular fractures from 2010 to 2011 between West China and East China

目的对比分析我国东部地区与西部地区成人髋臼骨折的流行病学特征。方法回顾性分析2010年1月至2011年12月我国东部地区与西部地区63家医院诊治的所有成人髋臼骨折患者资料。将东部地区35家医院患者资料定为东部地区组，西部地区28家医院患者资料定为西部地区组，对比分析两组患者的性别、年龄、各年龄段骨折例数、骨折AO分型及Letoumel—Judet分型等数据。结果共收治2009例成人髋臼骨折患者，男1510例，女499例，男女比为3．03：1。骨折高发年龄段为41～50岁（26．13％），高发骨折类型为62-A型（52．17％）。东部地区组1564例，西部地区组445例，其男女比分别为3．17：1、2．59：1，平均年龄分别为44．8、43．3岁，差异均无统计学意义（P〉0．05）。东部地区组和西部地区组骨折高发年龄段分别为41～50岁（26．09％）、31～40岁和41～50岁（均为26．29％）。两组骨折高发类型均为62-A型，但东部地区组62．A型骨折构成比（53．52％）显著高于西部地区组（47．42％），62．A型骨折患者男女比（3．41：1）也显著高于西部地区组（2．30：1），差异均有统计学意义（P〈0．05）。按Letoumel-Judet分型，两组骨折高发类型均为后壁骨折。结论我国东部地区与西部地区成人髋臼骨折均男性多于女性，东部地区骨折高发年龄段为41-50岁，西部地区为31-40岁和41-50岁。东部地区与西部地区患者均以62．A型骨折居多。两个地区均以后壁骨折常见。

Objective To compare and analyze the epidemiological features of adult acetabular fractures from 2010 through 2011 between East China and West China. Methods The data of adult acetabular fractures treated from January 2010 through December 2011 in 63 hospitals in West China and East China were collected through the PACS system and case reports checking system. The data from 35 hospitals in East China were assigned into East group and those from 28 hospitals in West China into West group. The analytic items included gender, age, age distribution, AO classification and Letournel-Judet classification. Results A total of 2, 009 cases were included, involving 1,510 males and 499 females with a male to fe- male ratio of 3.03： 1. The high risk age was from 41 to 50 years （26.13%） and the predominant type AO type 62-A （52. 17% ）. The male to female ratio was 3.17：1 in East group and 2.59：1 in West group, showing no significant difference （ P 〉 0. 05） ; the average age was 44.8 years in East group and 43.3 years in West group, showing no significant difference （ P 〉 0. 05）. The age distribution showed that the peak ranges were from 31 to 40 years old and from 41 to 50 years old in West group （both 26. 29% ）, and from 41 to 50 years old in East group （26. 09% ）. The high-risk type of fracture was 62-A in both groups, but the proportion of type 62-A in East group （53.52%） was significantly higher than that in West group （47.42%） （ P 〈 0. 05）. The male to female ratio in type 62-A fractures was 3.41 ： 1 in East group, significantly higher than that in West group （2.30： 1 ） （ P 〈 0. 05）. In both groups, the high-risk Letournel-Judet type was posterior wall frac- ture. Conclusions There were more male acetabular fractures than female ones in both East and West China. The peak age was from 41 to 50 years in the east area and from 31 to 50 years in the west area. In both East and West China, the high-risk type of fracture was 62-A and posterior wall fractures were the most common type.
