2010年至2011年中国东部和西部地区肩胛颈骨折的流行病学对比分析

Epidemiological survey of scapular neck fractures between the east and west areas in China from 2010 through 2011

目的对比分析我国东部和西部地区肩胛颈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所医院诊治的肩胛颈骨折患者资料，记录患者的性别、年龄和骨折Miller分型等数据。将东部地区35所医院的患者资料定为A组，西部地区28所医院的患者资料定为B组，对比分析两组患者的一般资料。结果共收集584例肩胛颈骨折患者，男女比为3．46：1；骨折高发年龄段为41—50岁（25．17％）；骨折根据Miller分型：Ⅰ型150例（25．68％），Ⅱ型306例（52．40％），Ⅲ型128例（21．92％）；稳定骨折426例（72．95％），不稳定骨折158例（27．05％）。A组427例，男女比为3．64：1；B组157例，男女比为3．03：1；两组患者男女比比较差异无统计学意义（P〉0．05）。A组患者中位年龄（44岁）大于B组（39岁），差异有统计学意义（P〈0．05）。A组和B组骨折高发年龄段分别为41—50岁和31—40岁，构成比分别为24．36％和36．31％；骨折高发类型均为Ⅱ型，构成比分别为51．52％和54．78％。两组患者骨折Miller分型分布比较差异均无统计学意义（P〉0．05）。结论肩胛颈骨折高发年龄段为41～50岁，高发类型为Miller Ⅱ型，多见于稳定骨折，男性多于女性。东部地区患者中位年龄高于西部。

Objective To compare the epidemiological characteristics of scapular neck fracture between the east and west areas in China from 2010 through 2011. Methods The data of scapular neck fractures treated between January 2010 and December 2011 at 35 east hospitals and 28 west ones were ana- lyzed retrospectively. The patients＇ gender, age and Miller 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 to find out the general epidemiological characteristics. Results A total of 584 scapular neck fractures were collected. The total male/female ratio was 3.46： 1. The scapular neck fractures predominated in an age range from 41 to 50 years （25.17%）. According to the Miller classification, there were 150 cases （25.68%） of type Ⅰ, 306 ones （52. 40% ） of type Ⅱ and 128 ones （21.92%） of type Ⅲ. 426 cases （72. 95% ） were stable fractures and 158 ones （27. 05% ） unstable fractures. The male/female ratio was 3.64：1 in group A of 427 patients and 3.03：1 in group B of 157 patients. There were no significant differences between the 2 groups in male/female ratio （P 〉 0.05）. The median age of group A （44 years） was significantly older than that of group B （39 years） . The fractures predominated in an age range from 41 to 50 years （24. 36% ） in group A and in the age range from 31 to 40 years （36.31%） in group B. The most frequent fracture type was type Ⅱ in both groups, accounting for 51.52% and 54. 78% respectively. There were no significant differences between the 2 groups in distribution of Miller classification （ P 〉 0. 05） . Conclusions The peak age of scapular neck fractures was from 41 to 50 years, the high-risk type was Miller type Ⅱ and stable fractures were more common. There were more male patients than female ones. The median age in the east area was older than that in the west area.
