Falls were the primary reason for injury with over three-quarters of the injuries occurring as the result of a fall．The severity of fall-related injuries had a lot to do with the height of the fall．Patients who were injured after falling from a height over 20 feet were 10 times more likely to be treated than patients who were injured falling from 20 feet or lower．
