Overview
what it is and why it mattersAn open fracture (also called a compound fracture) is a broken bone where the skin is also broken: the bone, or the area right around the break, is exposed to the outside world through a wound. That exposure is what makes it an emergency: bacteria reach the bone within minutes, and the chance of an infection that gets into the bone (osteomyelitis) or the joint (septic arthritis) goes way up. Surgeons grade how severe an open fracture is based on the size of the wound, how much muscle and skin has been stripped away, whether nearby blood vessels are torn, and how dirty the wound is. The most severe injuries usually need a plastic surgeon involved to cover the wound after the bone is fixed.
If you have an open fracture, the ER team will cover the wound with a saline-moistened dressing, start IV antibiotics within the first hour, check your tetanus status, and prepare you for surgery to wash out the wound and remove any dead or contaminated tissue (a process called irrigation and debridement).
Symptoms
what you may notice- Visible bone or a wound directly over the break, sometimes the bone pokes through; sometimes the wound is small but sits right where the fracture is.
- Significant bleeding from the wound, the torn soft tissue around the fracture bleeds more than a simple cut.
- Severe pain with any movement of the limb, the combination of a broken bone and an open wound makes even gentle motion excruciating.
- Deformity of the injured extremity, the limb may look bent, shortened, or rotated compared to the other side.
Diagnosis
exam first, imaging secondAn open fracture diagnoses itself: the bone is visible, or the wound sits right over the break. We get X-rays of the fractured bone and the joints above and below it, and a CT scan if the fracture pattern is complex. If a major artery may be torn, we check pulses and pressures in the limb and may order a CT scan of the blood vessels (a CT angiography) to see exactly which vessels are involved and whether they need repair.
How We Treat It
how care progresses, step by stepThe thing to understand about an open fracture is that the clock matters. The wound is open to bacteria, so the early steps are about protecting the bone from infection while the team gets you ready for surgery. The steps below run in the order they usually happen, each one building on the one before.
1
Cover the Wound and Start Antibiotics
Before anything else, the ER team covers the wound with a saline-moistened dressing and starts IV antibiotics, usually within the first hour, with broader coverage added for dirtier injuries. Your tetanus status is checked and updated if needed. Getting antibiotics in early is one of the biggest factors in whether the bone stays infection-free.
2
Wash Out the Wound in the OR
Every open fracture goes to the operating room for a wash-out that clears away dead and contaminated tissue, a step called irrigation and debridement. The classic teaching was to do this within 6 hours; current evidence accepts up to 24 hours for the less severe open fractures, as long as the IV antibiotics started promptly.
3
Stabilize the Bone
Once the wound is clean, the broken bone is stabilized. Sometimes that happens at the same surgery as the wash-out; sometimes it waits for a follow-up procedure after the wound has settled. For the most severe injuries, a plastic surgeon is usually involved to cover the wound after the bone is fixed.
Surgical Options
if non-operative care isn't enoughEvery open fracture goes to the OR for a wash-out and removal of dead, contaminated tissue (irrigation & debridement). The classic teaching was within 6 hours; current evidence accepts up to 24 hours for the less severe open fractures as long as IV antibiotics start promptly. The bone itself is then stabilized, sometimes at the same surgery, sometimes in a follow-up procedure once the wound is clean.

Frequently Asked
questions we hear in clinicWhat makes an open fracture different from a regular broken bone?
In an open fracture (also called a compound fracture), the skin over the break is also torn, so the bone or the area right around it is exposed to the outside world through a wound. That exposure is what makes it an emergency: bacteria can reach the bone within minutes, which raises the chance of an infection that gets into the bone (osteomyelitis) or the joint (septic arthritis).
Why is an open fracture treated as an emergency?
Because the bone is open to bacteria. The longer the wound stays exposed, the higher the risk of a deep infection. That is why the ER team covers the wound, starts IV antibiotics within the first hour, checks tetanus, and gets you ready for a surgical wash-out.
How is the severity graded?
Surgeons grade how severe an open fracture is based on the size of the wound, how much muscle and skin has been stripped away, whether nearby blood vessels are torn, and how dirty the wound is. The most severe injuries usually need a plastic surgeon involved to cover the wound after the bone is fixed.
Will I need surgery?
Yes. Every open fracture goes to the operating room for a wash-out that removes dead and contaminated tissue (irrigation and debridement). The bone itself is then stabilized, sometimes at the same surgery, sometimes in a follow-up procedure once the wound is clean.
How quickly does the surgery need to happen?
The classic teaching was within 6 hours. Current evidence accepts up to 24 hours for the less severe open fractures, as long as the IV antibiotics start promptly.
What imaging will I have?
We get X-rays of the fractured bone and the joints above and below it, and a CT scan if the fracture pattern is complex. If a major artery may be torn, we check pulses and pressures in the limb and may order a CT scan of the blood vessels (a CT angiography) to see exactly which vessels are involved and whether they need repair.
