2003年至2012年河北医科大学第三医院成人股骨远端骨折的流行病学分析

The epidemiological trends of adult distal femur fractures in the Third Affiliated Hospital to Hebei Medical University from 2003 through 2012

目的 探讨10年期间河北医科大学第三医院成人股骨远端骨折的流行病学特征及变化趋势. 方法 对2003年1月至2012年12月期间河北医科大学第三医院收治的成人股骨远端骨折患者资料进行回顾性分析,记录患者的性别、年龄及骨折AO分型等数据.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年期间成人股骨远端骨折的流行病学特征及变化趋势. 结果 共统计1 178例（1 217侧）成人股骨远端骨折患者,男814例（849侧）,女364例（368侧）,男女比为2.24∶1.骨折高发年龄段为31 ～ 40岁（21.45％）,高发骨折类型为33-A型（48.48％）.A组642例（667侧）,男女比为3.17∶1;平均年龄为（38.6±15.5）岁;B组536例（550侧）,男女比为1.55∶1;平均年龄为（46.8±18.3）岁.两组患者男女比和平均年龄比较差异均有统计学意义（P＜0.05）.与A组比较,B组16 ～20岁和31～40岁年龄段患者所占比例下降,≥61岁各年龄段患者所占比例升高,33-A型骨折患者所占比例下降,33-C型骨折患者所占比例升高,以上项目两组间比较差异均有统计学意义（P＜0.05）. 结论 成人股骨远端骨折男性多于女性,骨折高发年龄段为31 ～40岁,高发骨折类型为33-A型;与前5年比较,后5年男性患者所占比例下降,患者平均年龄升高,老年患者增多,关节内骨折所占比例增加.

Objective To investigate the epidemiological characteristics and trends of adult distal femur fractures treated in our hospital during the last 10 years.Methods We retrospectively analyzed the clinical data of adult patients with distal femur fracture who had been treated between January 2003 and December 2012 in our hospital.The patients＇ age,gender,fracture site and AO classification were documented.The data between January 2003 and December 2007 were assigned into group A and those between January 2008 and December 2012 in group B.The 2 groups were compared in terms of gender,age,age distribution and type of AO classification.Results A total of 1,178 adult distal femur fractures （1,217 sides）were collected,involving 814 males （849 sides） and 364 females （368 sides）,with a ratio of male to female of 2.24∶ 1.The peak age ranged from 31 to 40 years （21.45%）.Type 33-A was the most frequent type （48.48%）.In group A,there were 642 cases （667 sides）,with a male/female ratio of 3.17∶1 and a mean age of 38.6 ± 15.5 years.In group B,there were 536 cases （550 sides）,with a male/female ratio of 1.55∶1 and a mean age of 46.8 ± 18.3 years.Group A had significantly fewer females,a significantly younger mean age,significantly more patients in the age groups of 16 to 20 and 31 to 40 years,significantly fewer patients of above 61 years old,a significantly larger proportion of type 33-A,and a significantly smaller proportion of type 33-C than group B （P 〈 0.05）.Conclusions At our hospital between 2003 and 2012,there were more female adult patients with distal femur fracture than male ones; the peak age was from 31 to 40 years;the high-risk type of fracture was type 33-A; compared with the first 5 years,the second 5 years witnessed a decreasing proportion of male patients,an increased mean age,and increasing trends of elderly patients and intro-articular fractures.
