Which scenario is most likely to present with a visible deformity?

• A. Nondisplaced fracture
• B. Displaced fracture
• C. Hairline fracture
• D. Sprain

Answer: (B)

Visible deformity shows up when the bone ends are out of place, which happens with a displaced fracture. When the pieces of the bone are no longer aligned, the limb often looks bent, shortened, or twisted, and you can see an obvious contour change. In a nondisplaced fracture, the bone cracks but stays in proper alignment, so the limb’s shape usually remains normal even though there is pain and swelling. A hairline fracture is a tiny crack that often causes pain and tenderness but typically doesn’t produce a noticeable deformity. A sprain is an injury to ligaments around a joint, not to the bone itself, so deformity is not the usual feature there. So, the scenario most likely to present with a visible deformity is one where the fracture is displaced. If this is suspected, immobilize the area and seek medical care promptly.
