2人乗り自転車前転事故による小児顎関節突起完全骨折の2例 Two children with complete condylar process fractures caused by falling from the front child seats of bicycles
We report on two children with infantile condylar fractures, caused by falling from front child seats of bicycles.<BR>Patient 1 was a 5-year-old boy, and patient 2 was a 2-year-old boy. Both patients had fractures of the mandible with complete condylar fractures. The first patient had a complete left fracture, and the second patient had complete right and incomplete left fractures.<BR>Circumferential wiring with an occlusal plate was performed for fixation of the mandibular body fractures, and mouth opening exercises were started several days after wiring. The occlusal plate was extremely useful, but many potential problems, such as caries or tooth luxation, were considered in patient 1.<BR>These patients show that a child riding in a front child seat of a bicycle can sustain a hard blow to the face, head, or both in the event of an accident. Increased external force due to the mother's weight can increase the severity of fractures.
