豫北地区机动车摇柄伤的流行病学调查

Epidemiological investigation on motor vehicle engine shake shaft caused injuries in North Henan province

目的 对豫北地区机动车发动机摇柄伤的分布情况及其受伤机制进行分析。 方法 自 1998年 1月至 2 0 0 2年 5月 ,对我院就诊的 5 2 0例机动车发动机摇柄伤患者进行随访。根据性别、年龄和受伤时间、部位等 ,分析其流行病学特征。 结果 本组患者年龄 9～ 5 3岁 ,平均31岁 ;男 30 0例 ,女 2 2 0例 ,男女性别之比为 1.36∶1。主要以Colles骨折及尺桡骨远端骨折为主 ,占 73.8% (384 /5 2 0 )。发病时间以 5 ,6月份及 9,10月份为主 ,占 85 .0 % (4 4 2 /5 2 0 )。 结论 (1)机动车发动机摇柄伤主要致右侧前臂以远损伤 ,以Colles骨折及尺桡骨远端骨折为主。 (2 )其受伤原因绝大多数为操作不当所引起 ,主要发生在农忙季节。 (3)寻求减少损伤的对策 ,应以预防为主 ,增强安全操作观念及个人防护意识。同时改进机动车发动机结构 ,避免未成年人不当操作。

Objective To analyze the injury mechanism and distribution of the motor vehicle engine shake shaft caused injuries (MVESSCI) in North Henan province. Methods A follow up was done on 520 patients with the motor vehicle engine shaft injuries treated in our hospital from January 1998 to May 2002. The epidemiological features were analyzed concerning gender, age, injury time and injury sites. Results There were 300 males and 220 females (age range of 9-53 years, mean 31 years) with ratio 1.36 ∶1 of male to female. The MVESSCI were dominated by Colles fractures and distal fractures of ulna and radius, accounting for 73.8% (384/520). The traffic accidents occurred most in May, June, September and October, which accounted for 85.0% (442/520). Conclusions (1) The vehicle engine shake shaft causes the injuries mainly at the distal part of the right forearm, mainly the Colles fracture and the distal fractures of ulna and radius. (2) The injury is mainly due to improper operation in busy farming seasons. (3) The countermeasures to reduce wounds and injuries are to pay much more attention to prevention, strengthen the safety awareness of individuals, improve the structures of motor vehicles and avoid improper manipulation of the vehicles by children.
