摘要目的 探讨10年期间河北医科大学第三医院成人股骨头骨折的流行病学特征及变化趋势. 方法 回顾性分析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头骨折患者资料,记录患者的性别、年龄、骨折AO分型及Pipkin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年期间成人股骨头骨折的流行病学特征及变化趋势.结果 共统计251例成人股骨头骨折患者,占同期成人股骨近端骨折的3.43％ (251/7 315),占同期成人全身骨折的0.23％(251/107 648).男157例,女94例,男女比为1.67∶1.骨折高发年龄段为21 ～ 30岁.高发骨折类型:AO分型为31-C1型(42.23％),Pipkin分型为Ⅰ型(30.68％).A组106例,男68例,女38例;平均年龄为(44.1±18.6)岁.B组145例,男89例,女56例;平均年龄为(56.2±21.5)岁.与A组比较,B组占同期成人股骨近端骨折和全身骨折的比例均升高,平均年龄也增加,差异均有统计学意义(P＜0.05).B组患者31-C1型骨折构成比(48.28％)高于A组(33.96％),31-C2型骨折构成比(23.45％)低于A组(42.45％),两组患者骨折AO分型构成比比较差异有统计学意义(P＜0.05).结论 成人股骨头骨折少见,男性多于女性,骨折高发年龄段为21 ～ 30岁,骨折AO分型31-C1型、Pipkin分型Ⅰ型最多见;与前5年比较,后5年成人股骨头骨折占同期成人股骨近端骨折及全身骨折的构成比、31-C1型骨折构成比有增高趋势,而31-C2型骨折构成比有降低趋势.

abstractsObjective To investigate the epidemiological characteristics and trends of femoral head fractures in adults at the Third Affiliated Hospital to Hebei Medical University from 2003 through 2012.Methods The clinical data were collected of the adult patients with femoral head fracture who had been treated between January 2003 and December 2012 in our hospital.The data regarding gender,age and fracture types of AO and Pipkin classifications were recorded.The data between January 2003 and December 2007 were assigned into group A and those between January 2008 and December 2012 into group B.The 2 groups were compared to find out the general epidemiologic characteristics and trends in the recent 10 years.Results A total of 251 adult femoral head fractures were included in this study,accounting for 3.43％ (251/7,315) of the adult proximal femoral fractures and 0.23％ (251/107,648) of the total adult fractures at the same period.They were 157 males and 94 females,with a ratio of male to female of 1.67∶ 1.The peak age of femoral head fractures was from 21 to 30 years old.The most frequent fracture types were 31-C 1 by AO classification (42.23％) and type Ⅰ by Pipkin classification (30.68％).There were 106 cases in group A (68 males and 38 females with an average age of44.1 ± 18.6 years) and 145 cases in group B (89 males and 56 females with an average age of 56.2 ± 21.5 years).Compared with group A,the proportions of group B to the contemporary adult proximal femoral fractures and to the total adult fractures,as well as the mean age of group B,significantly increased (P ＜ 0.05).The percentage of type 31-C1 in group B (48.28％) was significantly higher than in group A (33.96％),and the percentage of type 31-C2 (23.45％) significantly lower than in group A (42.45％) (P ＜ O.05).Conclusions The adult femoral head fractures were not very common.They occurred more in males than in females.Their peak age ranged from 21 years to 30 years of age.Their predominant types were AO type 31-C1 and Pipkin type Ⅰ.Compared with the first 5 years,the second 5 years witnessed increased percentages of femoral head fractures to the contemporary adult proximal femoral fractures and to the total adult fractures,an increase in the percentage of type 31-C1 but a decrease in the percentage of 31-C2.
