Pattern of injuries in fatal falls from buildings.

When bodies are brought for autopsy it is sometimes unclear whether the injuries are due to a fall from a height or due to blunt trauma from other causes, especially when the bodies are found near buildings with no eyewitnesses available. Studies discussing the injury patterns in adults after falls exclusively from buildings are rare. A five-year retrospective study was carried out on 151 cases of fatal falls from buildings brought for autopsy. The aim was to assess the pattern of these injuries and identify features helpful in discriminating between these and injuries due to blunt trauma from other causes. The majority of cases comprised subjects who fell from heights of 10-20 feet (3-6m) with most falls occurring late at night or in the early morning. The pattern that emerged is quite distinct from ground level falls and pedestrian injuries. Abrasions are the commonest injury and bruises very rare. Lacerations are mostly on the head and skull fractures are evenly distributed between the vertex, base and vertex plus base. Subarachnoid haemorrhage is the commonest intracranial lesion. Extradural haemorrhage alone is rare. Fractures of ribs and cervical vertebrae are common and fractures of thoracic vertebrae and long bones are uncommon. Safety measures to prevent such falls have been suggested.
