摘　　要：目的对比分析我国东部和西部地区成人肱骨干骨折的流行病学特征。方法回顾性分析2010年1月至2011年12月我国东部地区35所医院和西部地区28所医院诊治的成人肱骨干骨折患者资料，记录患者的性别、年龄和骨折AO分型等数据。将东部地区35所医院患者资料定为A组，西部地区28所医院患者资料定为B组，对比分析两组患者的一般资料。结果共收集3659例成人肱骨干骨折，男女比为1．78：1；骨折高发年龄段为21～30岁（22．00％）；骨折AO分型：12-A型1883例（51．46％），12-B型1436例（39．25％），12-C型340例（9．29％）。A组2519例，男女比为1．57：1；B组1140例，男女比为2．39：1；两组患者性别构成比较差异有统计学意义（X2=30．063，P=0．000）。A组患者中位数年龄（43岁）大于B组（36岁），差异有统计学意义（Z=-8．563，P=0．000）。A组骨折高发年龄段为21-30岁（21．12％），B组为31．40岁（25．60％）。两组骨折高发类型均为12-A型，构成比分别为51．85％和50．61％。两组患者年龄分布比较差异有统计学意义（P〈0．05），骨折AO分型分布比较差异无统计学意义（P〉0．05）。结论成人肱骨干骨折高发年龄段为21～30岁，高发类型为12-A型，男性多于女性。东部地区女性患者构成比和平均年龄均高于西部地区。Objective To compare the epidemiological characteristics of adult humeral shaft frac- tures between the east and west areas in China from 2010 through 2011. Methods The data of adult humeral shaft fractures treated between January 2010 and December 2011 at 35 east hospitals and 28 west ones were analyzed retrospectively. The patients＇ gender, age and type of AO classification were documented. The data from the 35 east hospitals were classified as group A while the data from the 28 west ones as group B. Comparisons were made between the 2 groups to find out the general epidemiological characteristics. Results A total of 3, 659 adult humeral shaft fractures were collected. The total male/female ratio was 1.78： 1. The adult humeral shaft fractures predominated in an age range from 21 to 30 years （22.00%）. There were 1,883 cases （51.46%） of type 12-A, 1, 436 ones （39.25%） of type 12-B and 340 ones （9.29%） of type 12-C. The male/female ratio was 1.57：1 in group A of 2, 519 patients and 2. 39：1 in group B of 1,140 patients, showing a significant difference between groups （X2 = 30. 063, P = 0. 000） . The mean age of group A （43 years） was significantly older than that of group B （36 years） （ Z = - 8. 563, P = 0. 000） . The fractures predominated in the age range from 21 to 30 years （21.12%） in group A, and in the age range from 31 to 40 years （25.60%） in group B. The high-risk type was 12-A in both groups, accounting for 51.85% and 50. 61% respectively. The differences in age distribution were statistically significant between the 2 groups （ P 〈 0. 05 ）. There were no significant difference in the AO type distribution between the 2 groups （ P 〉 0. 05）. Conclusions The peak age of adult humeral shaft fractures was from 21 to 30 years, the high-risk type was 12-A and there were more male patients than female ones. The proportion of female patients and mean age in the east area were higher than those in the west area.
