The medical files of pregnant women involved in minor trauma, during 2009-2014, at 22-42 gestational weeks, were reviewed. Minor trauma was defined as an injury severity score<3, no immediate complains, normal ultrasound evaluation, reactive non-stress test, and no regular contractions. Patients were divided into those who, according to our departmental protocol, were hospitalized for 24h observation (hospitalized group), and those who refused to be hospitalized, (non-hospitalized group)
