| Objective: To research the characteristic of epidemiology and mechanism of the chest and venter injuries on road traffic accident; to discuss the distribution of disabled parts, degree of injury of road traffic accident and the proper time limit of assessment in order to offer reference for assessment and prevention of road traffic injuries; To explore the effective factors about medical treatment expense in later stage in the wounded of road traffic accident, in order to accumulate important material for forensic medicine evaluation. Method: According to the retrospective statistical analysis and the techniques of Forensic medicine, 210 cases with forensic pathology medicine and 247 cases with clinical forensic medicine were studied and analysed in the Center of Judicial Expertise of Kunming Medicine College in 2004 and 2005．Result: In the 457 cases, there were 297 male patients(65．0%), and 160 female patients(35．0%). The age distribution assumes to be the skew distribution, from 18 to 59 years old accounts for 74．4 percent of traffic accident rate. It is the highest percent of peasant in occupation distribution. The road traffic accident frequently occurs from 9 to 12 Am in a day, which accounts for 22．8 percent. The road traffic accident of children frequently occurs from 16 to 19 Pm, which accounts for 27．1 percent, the road accident of aged people frequently occurs from 9 to 12 Am, which accounts for 33．3 percent. The huge vehicles that cause trouble account for 61．1 percent in the death parts, while the tiny vehicles account for 41．3 percent in the disabled parts among all the traffic accident. Chest injury is the predominant death reason. Among the injured, the pedestrians and the non-automobile riders account for 60．7 percent in the traffic accident. The motorcyclists and the passengers are easily injured by tumbling. The number of wheel injury at in-car is higher than that of out-car, and there are no differences between out-car people. The percent of perineum injury in the motorcyclists and the non-autumobile riders is highest in complex injury. The passengers and the non-automobile riders are easily injured by centrums. The evaluation of chest and venter injuries fromⅧtoⅩstage accounts for 94．4% in evaluation, and the most disabled people is the pedestrians and the non-automobile riders, at the same time the injuries stage is higher. The disabled people are regarded wrinkly as principle, occupying 75．1%. Most of the sequela of the chest and venter injuries is movement obstacle which frequently happens on the non-automobile riders. The later stage evaluation of the chest and venter injuries from 3 to 6 months accounts for 66．8 percent in evaluation. The medical treatment expense in later stage is 2000-4000 yuan RMB as principle, occupying 63．4%. The evaluation of the medical treatment expense in later stage from 3 to 4 months accounts for 34．0%. Conclusion: The age distribution of the chest and venter injuries cases in the traffic accidents occurs frequently from 18-59 years old, the incident rate is the highest among the traffic accident; the rash hour of traffic accident for children is from 16 to 19 and 9 to 12 for aged people; the mechanism of the chest and venter injuries are caused by hitting in different vehicles. The number of spine injuries in disabled cases is highest which is most caused by huge vehicles. The distribution of the later stage is low-grade as principle; the time for later stage evaluation and the evaluation of the medical treatment expense in later stage need to synthesize the relevant factors to make an integrated decision. |
