A medical and engineering study was made of 1074 car accidents involving 2520 vehicle occupants. The injuries they sustained were correlated with details the crash contact points inside cars. Where possible forces which generated in estimated related to injuries. In all, 39 occupants suffered femoral shaft fracture, an incidence 1.7% 0.8% for front rear seat respectively. Of these, 31 had associated other regions body; these cause 13 14 deaths this group. Associated more severe who not wearing belts but fracture significantly different. mean velocity change (delta-V) causing 26 mph (42 km/h) there a higher when delta-V over 30 mph. Estimates needed than those found cadaver studies. time union fractures did correlate severity longer (mean 19 weeks) average fractures.
