2003年至2012年河北医科大学第三医院成人胫骨干骨折的流行病学研究

Epidemiological investigation and analysis of adult tibial shaft fractures in the Third Affiliated Hospital to Hebei Medical University from 2003 through 2012

目的 调查10年期间河北医科大学第三医院成人胫骨干骨折的流行病学特征,并分析其变化趋势.方法 对2003年1月至2012年12月河北医科大学第三医院收治的成人胫骨干骨折患者资料进行回顾性分析,记录患者的性别、年龄、骨折AO分型.将2003年1月至2007年12月的患者资料定为A组,2008年1月至2012年12月的患者资料定为B组,比较两组患者的一般资料,总结出10年期间成人胫骨干骨折的流行病学特征及变化趋势.结果 共收治5 502例成人胫骨干骨折患者,男4428例,女1 074例;42-A型骨折2 729例（49.6％）,42-B型骨折1 426例（25.9％）,42-C型骨折1 347例（24.5％）.A组3 766例,男女比为4.40∶1;B组1 736例,男女比为3.60∶1,两组患者性别构成比比较差异有统计学意义（x2=7.788,P=0.005）.A组患者平均年龄[（36.7±13.8）岁]小于B组[（39.8±15.4）岁],差异有统计学意义（t=7.460,P=0.000）.B组42-B、42-C型骨折的构成比较A组明显增加,达56.3％,差异有统计学意义（P＜0.05）.结论 成人胫骨干骨折男性多于女性;与前5年比较,后5年男性患者减少;42-B、42-C型骨折及60岁以上患者呈增多趋势.

Objective To investigate the epidemiological features and trends of tibial shaft fractures in adult patients who had been treated in our hospital from 2003 through 2012.Methods The data of adult tibial shaft fractures treated between January 2003 and December 2012 at our hospital were collected.The data between January 2003 and December 2007 were classified as group A while those between January 2008 and December 2012 as group B.Analytic items included gender ratio,age distribution and fracture type.The 2 groups were compared to find changing trends in the last decade.Results A total of 5,502 adult tibial shaft fractures were included for this investigation,with 4,428 males and 1,074 females.There were 2,729 cases of type 42-A （49.6%）,1,426 cases of type 42-B （25.9%）,and 1,347cases of type 42-C （24.5%）.Group A had 3,766 cases with a male/female ratio of 4.40∶1 and group B 1,736 cases with a male/female ratio of 3.60∶ 1.There was a significant difference in the male/female ratio between the 2 groups （x2 =7.788,P =0.005）.The mean age in group A （36.7 ± 13.8 years） was significantly younger than that in group B （39.8 ± 15.4 years） （t =7.460,P =0.000）.The proportion of 42-B and 42-C fractures in group B （56.3%） was significantly larger than that in group A （P 〈 0.05）.Conclusions This cohort is characterized by male predominance,a decrease in male patients in the latter 5 years,and an increase in 42-B and 42-C types as well as in patients older than 60 years old in the latter 5 years.
