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); Gram-negative, 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.
