Which type of fracture involves the bone breaking but the skin remains intact?

• A. Open fracture
• B. Closed fracture
• C. Simple fracture
• D. Stress fracture

Answer: (B)

The key idea is whether the skin is broken or not. A closed fracture means the bone has fractured but the skin over the fracture site remains intact. There’s no open wound, so the injury stays inside the body, which affects treatment and infection risk. In contrast, an open fracture involves a break in the skin, exposing bone and tissue and requiring more urgent medical care. A stress fracture is a hairline crack from repetitive loading and doesn’t define skin status, and a simple fracture describes a clean break without extensive damage but still implies the skin isn’t breached. So, when the skin remains intact while the bone breaks, it’s a closed fracture.
