What type of fracture does not break the skin?

A closed fracture is indeed characterized by the bone breaking without disrupting the integrity of the overlying skin. This type of fracture remains contained, which means there is no exposure of the wound to the external environment. The absence of a break in the skin reduces the risk of infection compared to fractured types that do break the skin.

In contrast, open and compound fractures refer to similar types of fractures where the skin is broken, allowing for direct communication between the outside and the fractured bone. While a greenstick fracture is a specific type typically seen in children where the bone bends and partially breaks, it also does not imply skin involvement as a defining feature. However, since the question specifically inquires about a fracture type that does not break the skin, the correct answer is the closed fracture, emphasizing that skin integrity remains intact.
