Objective To analyze the characteristic of trauma in 246 fatal falls. Methods We collect 246 cases of fatal falls from Pudong district of Shanghai from 2005 to 2014, and then analyze the characteristics of trauma by using different parameters. Results The height in suicides by fall is higher than accidents by fall (25.7m:13.98m). In all fatal falls, head has a higher possibility in suffering trauma than other body regions (75.2%), while neck has a lower possibility (6.5%). The possibility of head trauma in accidents by fall is higher than suicides by fall (89.4%:75.2%). Conclusion Comparing with suicides by fall, victims in accidents by fall have lack of protection from limbs. Besides, the low rate of ifnding neck trauma suggests legal physicians should be more careful in examining this area.%目的：对高坠案件进行统计分析，为相关鉴定研究提供参考。方法收集上海市浦东地区最近十年来记录有坠落距离的246例高坠案件，对人体损伤的特点进行比较分析。结果自杀高坠的高度显著高于意外高坠的高度(25.70m：13.98m)；所有高坠中，头部损伤概率较高(75.2%)，颈部损伤概率较低(6.5%)；意外高坠的头部损伤概率高于自杀组(89.4%：75.2%)。结论意外高坠的死者比自杀高坠的死者更缺乏四肢对于头部的保护；过低的颈部损伤发现率提示国内法医工作者应该更加重视在高坠案件中的对于颈部损伤的检查。
