摘要目的 分析成人尺、桡骨远端骨折的流行病学特征及变化趋势. 方法 利用医学影像计算机存档与传输系统及病案查询系统整理、分析2003年1月至2012年12月10年诊治的成人尺、桡骨远端骨折资料.将2003年1月至2007年12月患者资料定为A组,2008年1月至2012年12月患者资料定为B组,对比、分析两组患者的性别、年龄、各年龄段骨折数及骨折AO分型等.结果 共采集成人尺、桡骨远端骨折9 104例,占同期成人尺、桡骨骨折的65.8％(9 104/13 839),占同期成人全身骨折的8.5％(9 104/107 648).其中男3 934例,女5 170例,男女构成比为1∶1.3,高发年龄段为51～60岁,占25.0％(2 277/9 104),高发骨折类型为AO 23-A型,占75.3％(6 855/9 104).A、B两组成人尺、桡骨远端骨折数分别占同期成人尺、桡骨骨折的63.4％(4 631/7 307)和68.5％(4 473/6 532),差异有统计学意义(P＜0.05).B组男女比为1∶1.4,16 ～ 20岁患者构成比为6.5％ (290/4 473),高发骨折类型AO 23-A型的构成比为67.5％(3 021/4 473),均低于A组的1∶1.3、11.8％ (547/4 631)、82.8％(3 836/4 631);而B组50岁以上患者构成比为56.4％ (2 521/4 473),高于A组的48.7％(2 254/4 631),以上项目两组比较差异均有统计学意义(P＜0.05). 结论 2003年1月至2012年12月成人尺、桡骨远端骨折具有女性患者增多、青年人逐渐减少、老年人增多、骨折类型相对集中于23-A型,但23-B型和23-C型有增加的趋势.

abstractsObjective To analyze the epidemiological features and trends of distal ulna and radius fractures in adult patients.Methods The data of adult fractures of distal ulna and radius from January 2003 through December 2012 at our hospital were collected and analyzed through the PACS system and the case records review system.The data between 2003 and 2007 were assigned into group A and those between 2008 and 2012 into group B.The 2 groups were compared in terms of gender,age,age distribution and type of AO classification.Results A total of 9,104 adult distal ulna and radius fractures were collected,accounting for 65.8％ (9,104/13,839) of the adult radius and ulna fractures and 8.5％ (9,104/107,648) of the adult fractures during the same time.They involved 3,934 males and 5170 females,with a male/female ratio of 1∶ 1.3.The predominant age of the fractures concerned was from 51 to 60 years,accounting for 25.0％ (2,277/9,104).The high-risk type of fracture was type 23-A,accounting for 75.3％ (6,855/9,104).There were 4,631 cases in group A and 4,473 cases in group B,respectively accounting for 63.4％ (4,631/7,307) and 68.5％ (4,473/6,532) of all the adult radius and ulna fractures in each group at the same time,giving a significant difference between groups (P ＜0.05).In group B,the male/female ratio was 1∶ 1.4,the proportion of patients aged from 16 to 20 was 6.5％ (290/4,473),the proportion of high-risk type 23-A was 67.5％ (3,021/4,473),all significantly lower than those in group A [1∶ 1.3,11.8％ (547/4,631) and 82.8％ (3,836/4,631)] (P ＜ 0.05).The proportion of patients aged above 50 years in group B was 56.4％ (2,521/4,473),significantly higher than that in group A [48.7％ (2,254/4,631)] (P ＜0.05).Conclusions The adult patients with distal ulna and radius fractures treated at our hospital from 2003 through 2012 were characterized by an increase of females,a reduction of teenagers,an increase of the elderly and predominance of AO type 23-A.
