What type of fracture is typically simple and does not break the skin?

A closed fracture is characterized by the fact that the bone breaks without causing any disruption to the surrounding skin. This type of fracture remains contained within the body, which means there is no external exposure to the environment, reducing the risk of infection that can occur with open or compound fractures. Closed fractures can occur in various ways, such as due to falls, sports injuries, or accidents, and they generally heal relatively well provided the bone is properly aligned, allowing for optimal healing without external complications.

In contrast, open and compound fractures involve the skin being broken, which can lead to complications such as increased risk of infection and require more intensive medical treatment. A complex fracture often refers to one with multiple fragments or associated injuries, indicating a higher level of severity, again contrasting with the simplicity of a closed fracture. Therefore, the correct answer accurately defines a fracture type that remains uncomplicated, without skin injury.
