## **Core Concept**
A spider web fracture refers to a type of fracture pattern seen in bones, particularly in the context of osteoporotic or pathologic fractures. This pattern resembles the web of a spider, with multiple, radiating, and interconnecting fracture lines.

## **Why the Correct Answer is Right**
The term "decompression fracture" or more commonly, **compression fracture**, is often used to describe fractures that result from the collapse of bone, typically in the vertebral bodies due to osteoporosis or trauma. A compression fracture can exhibit a "spider web" or "crushed" appearance on radiographs due to the bone's collapse. This type of fracture is most closely associated with the description of a spider web fracture.

## **Clinical Pearl / High-Yield Fact**
A key clinical correlation to remember is that **compression fractures** are a common cause of back pain in elderly patients, especially those with osteoporosis. These fractures can lead to kyphosis (a forward rounding of the back) and are often associated with minimal trauma.
