Bone Exposure (Open Fracture): Medical Term, Risks, and Urgent Treatment
The medical term for visible bone through a wound is open fracture (formerly "compound fracture") with bone exposure. It is a surgical emergency.
Immediate Risks
- Infection (osteomyelitis) – high without prompt irrigation/debridement.
- Neurovascular injury.
- Compartment syndrome.
- Delayed union or nonunion.
Emergency Management
- Control bleeding (direct pressure; tourniquet if life-threatening).
- Cover with sterile saline-moistened dressing.
- Immobilize (splint).
- IV antibiotics (typically cefazolin ± aminoglycoside for Gustilo III).
- Tetanus prophylaxis.
- Urgent orthopedic surgery: irrigation, debridement, stabilization (external fixation or ORIF).
Gustilo-Anderson classification (I–IIIC) guides treatment and prognosis. Time to debridement (<6–8 hrs) critically affects infection risk.
