2010年至2011年中国东部地区与西部地区成人髌骨骨折的流行病学对比分析

Epidemiological comparison of adult patella fractures from 2010 to 2011 between east and west areas in China

目的对比分析我国东部地区与西部地区成人髌骨骨折的流行病学特征。方法回顾性分析2010年1月至2011年12月期间我国东部地区与西部地区63家医院诊治的成人髌骨骨折患者资料。将东部地区35家医院患者资料定为A组，西部地区28家医院患者资料定为B组，对比分析两组患者的性别、年龄及骨折AO分型等数据。结果共收治8469例成人髌骨骨折患者，男4985例，女3484例，男女比为1．43：1。骨折高发年龄段为51～60岁（23．15％）；高发骨折类型为34．C型（72．76％），高发骨折亚型为34-C1型（39．73％）。A、B两组患者男女比均为1．43：1。A组患者的中位年龄（50岁）显著大于B组患者（46岁），差异有统计学意义（Z=2．714，P=0．000）。A、B组患者骨折高发年龄段分别为51～60岁（24．74％）、41—50岁（20．41％），两组骨折高发年龄段患者构成比比较差异有统计学意义（P〈0．05）。A、B两组患者高发骨折类型均为34-C型，构成比分别为74．08％、69．99％；高发骨折亚型均为34-C1型，构成比分别为42．56％、33．79％。结论我国东、西部地区成人髌骨骨折男性均多于女性，东部地区成人髌骨骨折患者的年龄大于西部地区。东部地区骨折高发年龄段为51—60岁，西部地区骨折高发年龄段为41～50岁。东、西部地区高发骨折类型均为34-C型，高发骨折亚型均为34-C1型。

Objective To compare and analyze the epidemiological features of adult patellar frac- tures between the east and west areas in China. Methods The data of adult patellar fractures treated between January 2010 and December 2011 in 63 hospitals in the east and west areas in China were collected through the PACS system and case reports checking system. The data from 35 east hospitals were assigned into group A and those from 28 west hospitals into group B. The analytic items included general situation, gender, age, AO classification. Results A total of 8,469 adult patellar fractures were collected, involving 4, 985 males and 3,484 females with a male to female ratio of 1.43： 1. The patellar fractures predominated in pa- tients of 51 to 60 years old （23.15%）; the high risk fracture type is 34-C （72.76%） with 34-C1 being the most common subtype （39. 73% ）. The male to female ratio was 1.43：1 in both groups. The median age of group A（50 years old） was significantly older than that of group B （46 years old） （ Z =2. 714, P =0. 000）. The high risk age was from 51 to 60 years in group A （24. 74% ） and from 41 to 50 years in group B （20. 41% ）, showing a significant difference （ P 〈 0. 05） . The high risk fracture type was 34-C in both groups （74. 08% in group A versus 69. 99% in group B）; the high risk sub-type was 34-C1 in both groups （42. 56% in group A versus 33.79% in group B） . Conclusions There were more male adult patellar fractures than female ones in the east and west areas in China. The age of patients with patellar fracture in the east area was older than that in the west area. The peak age was from 51 to 60 years in the east area and from 41 to 50 years in the west area. The most frequent type was 34-C and the most common subtype was 34-C1 in both east and west areas.
