A mandibular fracture not all the way through is called a Greenstick fracture because the bones do not completely separate, similar to a green branch that bends but does not break. Option A, an open fracture, refers to a fracture that breaks through the skin. Option B, a comminuted fracture, refers to a fracture that breaks into more than two pieces. Option C, a compound fracture, refers to a fracture that breaks through the skin and creates an open wound. These types of fractures are more severe and require immediate medical attention. Thus, they are not the correct answer for this question. The correct answer, D, is the most accurate term for a fracture that is not completely broken.
