Which fracture is also called an open fracture?

• A. Closed fracture
• B. Compound fracture
• C. Comminuted fracture
• D. Depressed fracture

Answer: (B)

The main idea is understanding what makes a fracture open: the skin over the fracture is broken, creating an open wound that communicates with the fracture site. That condition is described by the term compound fracture, which is another name for an open fracture.

So, an open fracture means the bone has broken and skin is torn, exposing bone to the outside environment — infection risk is higher, and it often requires urgent care and surgical intervention. The other terms describe different aspects of the break but not whether the skin is broken: a closed fracture has skin intact; a comminuted fracture means the bone is in many pieces; a depressed fracture usually refers to a bone pushed inward, often in the skull.
