ABSTRACT
<p><b>OBJECTIVE</b>To analyze the related factors of the infection after operation of open tibiofibula fractures.</p><p><b>METHODS</b>The clinical data of 141 patients with open tibiofibula fractures underwent surgical treatment from June 2009 to December 2012 were retrospectively analyzed. All the patients were male and aged from 18 to 61 years old with an average of 39.2 years; all the fractures were unilateral. According to Gustilo typing of fracure, 5 cases were type I, 44 cases were type II, 27 cases were type III a, 56 cases were type III b and 9 cases were type III c. These clinical data included patients' age, gender, body mass index (BMI), underlying diseases, time of operation, fracture site, fracture type, fixation method, postoperative drainage, debridement condition and so on. The postoperative infection conditions were recorded, and the correlation between above factors and infections were analyzed. Finally, the significant related variables were introduced into a Logistic regression model to evaluated their risk.</p><p><b>RESULTS</b>Among the 141 patients, 22 cases developed with infection (15.6%). The significant relative factors with infection contained fixation method, debridement condition, underlying diseases and postoperative drainage (P < 0.05). The correlativities were stepped up in order, their odds ratios value was 2.451, 3.164, 3.414, 5.117, respectively.</p><p><b>CONCLUSION</b>Active treatment for underlying diseases before operation, thorough debridement for open wound, suitable fixation method for fracture and thorough draining are effective measures in preventing postoperative infection.</p>
