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 distribution of crankshafts of motor vehicles in the north of Henan Province and their injuries. Methods From January 1998 to May 2002, 520 patients with craniocerebral-traumatic brain injury from motor vehicles in our hospital were followed up. According to gender, age and time of injury, location, etc., analysis of its epidemiological characteristics. Results The age ranged from 9 to 53 years (average 31 years). There were 30 males and 220 females with a gender ratio of 1.36: 1. Colles fractures and distal radius fractures were the major causes, accounting for 73.8% (384/520).

Conclusions (1) The motor crankshaft injury mainly to the right forearm far damage, to Colles fracture and distal radius and ulna fractures. (2) Most of the causes of the injuries were caused by improper operation, mainly during the busy season. (3) To seek measures to reduce injuries, we should take preventive measures as the main measures to enhance safety operation concepts and personal protection awareness. At the same time improve the motor vehicle engine structure, to prevent improper operation of minors.
