In open fractures, what is the immediate critical step in management?

• A. Immobilization
• B. Immediate broad-spectrum IV antibiotics and stabilization
• C. Analgesia only
• D. Surgical debridement

Answer: (B)

Open fractures carry a high risk of infection because the wound communicates with the fracture and surrounding tissues are easily contaminated. The most urgent threat is bacterial infection, which antibiotics directly address. Starting broad-spectrum IV antibiotics as soon as possible dramatically reduces the risk of infection and osteomyelitis, while simultaneous limb stabilization minimizes ongoing tissue injury and helps the antibiotic reach the wound more effectively.

Analgesia is important for comfort, but it doesn’t tackle infection risk. Immobilization alone helps with alignment and pain but doesn’t prevent contamination. Surgical debridement is essential and should occur promptly, but it is not the initial step in the ED—antibiotics and stabilization come first to control infection risk and prepare for definitive surgical care.
