Which fracture type is characterized by a horizontal fracture through the epiphyseal plate and partial separation of the epiphysis?

The fracture type characterized by a horizontal fracture through the epiphyseal plate with partial separation of the epiphysis is indeed the Type 2 fracture. This classification follows the Salter-Harris classification system, which is used to categorize fractures that involve the growth plate in children.

In a Type 2 fracture, the fracture line travels horizontally through the growth plate (epiphyseal plate) and then extends into the metaphysis. This results in partial separation of the epiphysis from the bone, while still maintaining a connection with part of the bone. This type of fracture is significant because it can affect growth and development if not managed properly.

Understanding the implications of each fracture type within the context of growth plate injuries is crucial in pediatric orthopedics, as improper healing can lead to complications such as growth disturbances or deformities.
