Reducing Complications in Pilon Fracture Surgery: Surgical Time Matters

Area of Science:

• Orthopedic Surgery
• Trauma Surgery
• Surgical Outcomes Research

Background:

• Distal intra-articular tibia (pilon) fractures are complex injuries requiring surgical intervention.
• Patient-specific and surgeon-specific factors can influence the success of operative management.
• Understanding these factors is crucial for optimizing treatment strategies and patient outcomes.

Purpose of the Study:

• To identify patient-specific and surgeon-specific factors associated with outcomes after operative management of pilon fractures.
• To correlate specific variables with the occurrence of complications such as infection, nonunion, and need for revision.

Main Methods:

• Retrospective cohort study involving 175 patients with OTA/AO 43-C pilon fractures treated at three academic trauma centers.
• Analysis of patient demographics, comorbidities (Charlson Comorbidity Index), smoking status, and surgical variables including operative time and fixation techniques.
• Primary outcomes assessed were superficial and deep infection; secondary outcomes included nonunion, loss of articular reduction, and implant removal.

Main Results:

• Increased age, smoking, and higher Charlson Comorbidity Index scores were associated with higher rates of superficial infection, nonunion, and loss of articular reduction, respectively.
• Each 10-minute increase in operative time beyond 120 minutes correlated with increased odds of infection and implant removal.
• Addition of fibular plating also increased the likelihood of infection and implant removal, while the number/type of approaches and bone grafting did not significantly impact infection rates.

Conclusions:

• While some patient factors (age, smoking, comorbidities) are non-modifiable predictors of adverse outcomes in pilon fracture surgery, surgeon-controlled factors like operative time and the extent of fixation require careful consideration.
• Minimizing operative time and judiciously applying additional fixation, such as fibular plating, may help reduce complication rates.
• Balancing the potential benefits of extensive fixation against the increased risks associated with longer operative duration and complexity is essential for optimal pilon fracture management.
