Which sign is most concerning for potential neurovascular compromise after fracture?

• A. Diminished sensation and movement of the feet
• B. Fever and redness
• C. Normal pulses
• D. Edema only

Answer: (A)

Neurovascular compromise after a fracture is most worrisome when there are signs of nerve or arterial involvement that affect sensation and movement. Diminished sensation and reduced ability to move the toes or foot suggest that nerves are being compressed or damaged and that distal blood flow or tissue viability may be at risk. This kind of sensory and motor deficit points to potential limb-threatening injury and requires urgent assessment to prevent irreversible damage, such as nerve loss or muscle necrosis.

Fever and redness point to infection rather than acute neurovascular issues, and normal pulses do not rule out problems like compartment syndrome where perfusion can be impaired even if pulse is present. Edema can occur with fractures but, by itself, does not indicate neurovascular compromise.
