Which type of Salter-Harris classification indicates a fracture of both the physeal and metaphyseal portions?

The Salter-Harris classification system is used to categorize growth plate fractures in children based on the involvement of the epiphyseal plate (physeal) and surrounding structures. In particular, Type 4 fractures involve both the physeal portion and the metaphysis. This type of fracture crosses through three different zones: the epiphyseal plate (physis), the metaphysis, and the epiphysis.

This classification is crucial because it helps determine the potential impact on growth and development of the bone. Type 4 fractures can lead to more significant implications for future growth compared to fractures that involve only one of these areas. Understanding the anatomy involved and the implications of these classifications is essential in providing appropriate management and treatment for pediatric fractures.
