—We wish to thank Dr. Moorman for his comments and observations. Fractures of the orbit (without rim fracture) caused by small rigid objects are classified as penetrating internal fractures. Blowout fracture, however, is a term indicating indirect injury in contradistinction to direct forces exerted by objects such as fingers, sticks, ice picks, and fishing rods. A blowout fracture, by definition, is not due to direct trauma from rigid, penetrating devices. We believe the fractures described by Dr. Moorman were penetrating internal fractures caused by a finger, or blowout fractures caused by the hand which followed the finger in striking the anterior orbit.
