Question
What factors affect infection after open long bone fractures, and how should these injuries be classified and treated?
Design
Combined retrospective and prospective case series from a single US centre.
Patients
Over one thousand open fractures of long bones.
Intervention
Debridement, irrigation, antibiotics and primary closure or delayed closure depending on wound type
Comparison
Different wound types and treatment approaches
Primary outcome
Infection rate
Key result
Introduced the Gustilo-Anderson classification (types I to III) and showed infection risk rose with severity of soft tissue injury, supporting prophylactic antibiotics and leaving severe wounds open.
Limitations
Observational single-centre data, and the classification has only moderate interobserver reliability and should be assigned after debridement.
Impact on practice
The classification remains the standard language for describing open fractures in the UK, and the paper established antibiotics as part of open fracture care.
