Summary

The Gustilo classification can predict infection risk in open fractures. Patients with more immune compromising factors face significantly higher infection rates, suggesting tailored therapies are needed.

Area of Science:

  • Orthopedic Surgery
  • Infectious Disease Epidemiology

Background:

  • Open fractures carry a high risk of infection.
  • Assessing infection risk in open fractures is crucial for patient outcomes.
  • The Gustilo classification is established for osteomyelitis but its utility in open fractures is unexplored.

Purpose of the Study:

  • To evaluate the applicability of the Gustilo classification in predicting infection risk in adult patients with open long bone fractures.
  • To identify comorbid medical illnesses that increase infection risk in open fracture patients.

Main Methods:

  • Retrospective review of 174 adult patients with open long bone fractures.
  • Classification of patients into Class A (no compromising factors), Class B (1-2 factors), and Class C (>3 factors) based on 14 immune system compromising factors.

  • Statistical analysis to examine the association between classification and infection incidence.

    • Main Results:

    • Infection incidence was 4% (Class A), 15% (Class B), and 30% (Class C).
    • Class B patients were 2.86 times more likely to develop infection compared to Class A.
    • Class C patients were 5.72 times more likely to develop infection compared to Class A.

    Conclusions:

    • The Gustilo classification is applicable to open fractures for identifying infection risk.
    • Immune compromising factors, fracture location, and tobacco use are associated with infection.
    • Patients classified as B or C have a markedly increased risk of infection and may benefit from targeted therapies.
