Objective :to Analysis of the influencing factors and prevention countermeasures of incision in‐fection after traumatic fracture surgery ,provide theoretical basis of early prevention and control method of trauma infection .Methods :A retrospective analysis of 300 cases of hospitalized patients with traumatic fracture from Janu‐ary 2011 ‐ September 2013 in our hospital ,18 cases of which occurred postoperative incision infection ,set as observa‐tion group ,select 18 patients that was found at the same time without incision infection ,as control group ,compared clinical data of two groups ,summarize the high risk factors of postoperative incision infection and designated a series of preventive countermeasures .Results :18cases out of 300 cases occurred postoperative incision infection ,infection rate was 4 .2% ,the pathogen separation results :staphylococcus aureus ,accounted for 32 .35% respectively ,the epi‐dermis staphylococcus was 20 .58% ,two groups of patient's age ,body index ,the basic diseases ,types of incision , the average time of debridement and steel plate using ,surgical site ,operation time and postoperative hospital stay has statistically significant difference .Conclusion :Postoperative incision infection of traumatic fractures patient's own condition such as type of incision ,debridement time ,steel use ,surgical site ,operation time and postoperative hospi‐tal stay and other related factors ,risk factors should be aimed at these corresponding prevention measures ,and to re‐duce the incidence of traumatic fracture patients postoperative incision infection .%目的：探讨创伤骨折患者出现术后切口感染的相关危险因素以及早期预防对策，创伤后早期的感染预防、控制依据理论。方法：回顾性分析2009年1月至2014年1月间我院收治300例创伤骨折住院患者的临床资料，其中共有18例患者出现术后切口感染，将其作为研究组，选取同时期未出现切口感染的18例患者对照组，比较两组患者的临床资料，总结出现术后切口感染高危因素并针对其指定一系列的预防对策。结果：300例患者中总共出现18例术后切口感染，感染率为6％，病原菌分离结果分别为金黄色葡萄球菌占32．35％，表皮葡萄球菌占20．58％，两组患者的年龄、体重指数、基础疾病、切口类型、平均清创时间、钢板使用与否、手术部位、手术时间及术后住院时间的比较有统计学差异。结论：创伤骨折术后出现切口感染与患者自身情况如切口类型、清创时间、钢板使用、手术部位、手术时间及术后住院时间等因素相关，应针对这些危险因素给予相应预防措施，降低创伤骨折患者出现术后切口感染的发生率。
