Which fracture involves the collapse of a bone, especially in vertebrae?

• A. Compression fracture
• B. Open fracture
• C. Hematoma
• D. Bony callus

Answer: (A)

The question is testing the type of fracture defined by how the bone fails under load—specifically a fracture caused by crushing forces that collapse the bone, which is most common in the vertebral bodies. In a compression fracture, the vertebral body is crushed along its vertical axis, leading to loss of height and often a wedge-shaped vertebra. This mechanism is typical when axial load compresses weakened bone, as seen with osteoporosis or traumatic impact. It’s distinct from an open fracture, where the bone breaks through the skin; from a hematoma, which is simply a collection of blood outside vessels; and from a bony callus, which is new bone formed during healing after a fracture. Therefore, compression fracture best describes the collapse of a bone, especially in vertebrae.
