2010年至2011年中国东部地区和西部地区成人股骨干骨折流行病学对比分析

Epidemioiogical comparison of adult femoral shaft fractures between West China and East China from 2010 to2011

目的对比分析我国东部地区与西部地区成人股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所医院与西部地区28所医院诊治的成人股骨干骨折资料，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。结果共收治5980例成人股骨干骨折患者，占同期成人股骨骨折的21．21％（5980／28193），占全身骨折的2．18％（5980／274134）。男女比为3．13：1，高发骨折类型为32．A型（49．75％）。A、B组成人股骨干骨折分别为4257例和1723例。A组男女比（3．01：1）明显低于B组（3．44：1），差异有统计学意义（X2=3．864，P=0．049）。两组骨折高发类型均为32-A型，A组32．C型骨折所占比（14．21％）高于B组（10．68％），差异有统计学意义（X2=13．366，P〈0．001）。结论东部地区与西部地区成人股骨干骨折占该地区成人股骨骨折的21．21％，占全身骨折的2．18％。男性患者多于女性，32-A型骨折最常见。东部地区男女比较西部地区低，患者平均年龄较西部地区高。东部地区32-C型骨折所占构成比高于西部地区。

Objective To compare and analyze the epidemiological features of adult patients with femoral shaft fracture between East China and West China. Methods The data of adult patients with femoral shaft fracture treated from January 2010 to December 2011 in 63 hospitals in West China and East China were collected through the PACS system and case reports checking system. The data from 28 hospitals in West China were Classified as West group while those from 35 hospitals in East China as East group. The analytic items included gender, age, age distribution and type of AO classification. Results A total of 5, 980 adult femoral shaft fractures were selected with a male to female ratio of 3. 13： 1, accounting for 21.21% （5, 980/28, 193） of the adult femoral fractures and 2. 18% （5, 980/274, 134） of all the adult fractures. AO type 32-A was the most common, accounting for 49.75% of all the femoral shaft fractures. There were 4, 257 femoral shaft fractures in East group and 1,723 in West group. The male to female ratio was 3.44：1 in West group, significantly higher than in East group （3.01： 1） （X2 =3. 864, P =0. 049）. The high-risk type of fracture was 32-A in both West and East groups. The proportion of type 32-C fractures in East group（14. 21% ） was significantly higher than in West group（10. 68% ） （X2 = 13. 366, P 〈 0. 001）. Conclusions Adult femoral shaft fractures in East China and West China accounted for 21.21% of the adult femoral fractures and 2. 18% of all the adult fractures from 2010 to 2011. They were more common in males than in females. The most common fractures were AO type 32-A. The male to female ratio in East China was lower than in West China. The patients in East China were older than in West China. The proportion of type 32-C fractures in East China was higher than in West China.
