As outlined by MedlinePlus, several types of skull fractures can occur in a typical bicycle accident, such as a:
– simple fracture in which there is a crack in the bone, but no damage to the skin;
– linear skull fracture in which there is a fracture in the cranial bone, without depression, splintering or distortion of the bone;
– depressed skull fracture in which there is a fracture in the cranial bone with depression of the bone for the brain; and
– a compound fracture in which the skin may be damaged, and bone may be splintered.
