Which sign suggests possible distal neurovascular compromise in an open fracture?

• A. Pain with movement
• B. Loss of pulse or sensation distally
• C. Mild swelling
• D. Normal color of skin

Answer: (B)

Distal neurovascular compromise shows up when the limb can’t rely on its usual blood supply or nerve function, so the most telling sign is losing a distal pulse or distal sensation. If an artery is injured or the surrounding tissue compresses, blood flow to the hand or foot may drop, and the patient may also lose protective sensation in the area beyond the injury. This combination is a red flag that the limb’s perfusion and nerve work could be at real risk, requiring urgent evaluation and intervention.

Pain with movement, mild swelling, or a normal skin color can occur with fractures themselves and don’t specifically indicate compromised blood flow or nerve function. They’re less reliable as signs of neurovascular injury, which is why loss of distal pulse or distal sensation is the best indicator in this scenario.
