title: Helmet-induced skull base fracture in a motorcyclist.
abstract: Observations after a fatal motorcycle accident suggested that the face bar of a full-face helmet may transmit an impacting force to the skull base via the chin strap and the mandibular rami and condyles, bypassing the energy-absorbing facial bones. If this mechanism is confirmed, the structural properties of these face bars will need to be reassessed.
