Which symptom can be used to rule out a fracture?

• A. Degree of pain
• B. Extent of mobility
• C. Degree of swelling
• D. No symptom can rule out a fracture

Answer: (D)

The key idea is that you cannot rely on a single clinical sign to rule out a fracture. Fractures can be occult: there may be little or no pain, only mild swelling, or near-normal movement early on, yet a bone can still be fractured. Because of this, none of the individual symptoms—pain level, how much the limb can move, or how swollen it is—can definitively exclude a fracture. Imaging is needed to confirm or rule out the injury. In practice, if the mechanism of injury and exam raise suspicion, immobilize the limb and obtain radiographs, with repeat X‑rays or more sensitive imaging (like MRI or CT) if suspicion remains or symptoms don’t improve. So, no symptom can reliably rule out a fracture.
