What type of fracture occurs through cartilage or the growth plate?

A transchondral fracture specifically refers to a type of fracture that occurs through the cartilage or across the growth plate (also known as the epiphyseal plate). This is particularly significant in pediatric patients where the growth plate is still open, as it can affect future bone growth and development. Understanding this fracture type is crucial in clinical settings, especially when diagnosing injuries in growing children or adolescents, as it often requires specific management to prevent complications that could arise from improper healing.

The other types of fractures mentioned do not involve the growth plate or cartilage in the same way. A greenstick fracture typically occurs in children and involves an incomplete fracture on one side of the bone, resembling a bend rather than a complete break. A compound fracture (or open fracture) involves a break through the skin with potential exposure to the surrounding environment, while a simple fracture (or closed fracture) refers to a complete break in the bone without any such exposure. Each type of fracture has distinct characteristics and implications for treatment and recovery.
