What is an impacted fracture?

An impacted fracture is characterized by the bone ends being driven into each other, resulting in a form of fracture where the fragments are compressed. This type of fracture commonly occurs from high-energy impacts, such as during falls or accidents, where one part of the bone is pushed into another part. The unique nature of an impacted fracture can often lead to a more stable fracture pattern compared to other types because the ends are interlocked, potentially aiding in the healing process.

In contrast, the other options describe different types of fractures: those that are pulled apart represent distraction fractures, repetitive overuse leads to stress fractures, and bending without breaking pertains to greenstick fractures, primarily seen in children. Each of these types highlights distinct mechanisms and presentations of bone injuries, emphasizing the specific definition and characteristics of an impacted fracture.
