摘要
BACKGROUND High-energy tibial pilon fractures are complex and severe fractures that are associated with a high risk of infection following open reduction and internal fixation.Infection can negatively impact patient outcomes.AIM To compare risk factors for postoperative infection after open reduction and internal fixation for a pilon fracture.METHODS Among the 137 patients included,67 developed a surgical site infection.Demographic,clinical,and surgical factors were compared between the two groups.A binary logistic regression analysis was used to determine the odds ratio(OR)and corresponding 95% CI for significant risk factors for postoperative infection.RESULTS The distribution of pathogenic bacteria among the 67 patients who developed a surgical site infection was as follows:Gram-positive,58.2%(n=39);Gramnegative,38.8%(n=26);and fungal,2.9%(n=2).The following factors were associated with postoperative infection(P<0.05):a Ruedi–Allgower pilon fracture type Ⅲ(OR=2.034;95%CI:1.109–3.738);a type Ⅲ surgical incision(OR=1.840;95%CI:1.177–2.877);wound contamination(OR=2.280;95%CI:1.378–3.772);and diabetes as a comorbidity(OR=3.196;95%CI:1.209–8.450).CONCLUSION Infection prevention for patients with a Ruedi–Allgower fracture type Ⅲ,surgical incision type Ⅲ,wound contamination,and diabetes lowers the postoperative infection risk after surgical management of tibial pilon fractures.
