The bony eye socket structure is called the Orbit. Any type of blunt force facial trauma can damage the orbital bones and cause an orbital fracture. A fracture is a broken bone in the eye socket involving the rim, the floor or both. These fractures are commonly caused by a blunt object striking the eye socket, such as a rock, baseball, hockey stick, hammer, fist or even as a result of falling off a bicycle or during a car accident. Different types of orbital fractures can occur since the rim of the socket is made of fairly thick bones, while the floor and nasal side of the socket is paper thin in many places. These include: Orbital Rim Fractures, Blowout Fractures or Direct Orbital Floor Fractures.
