Purpose The purpose of the work is to evaluate the differences between the routine accesses to Pediatric Emergency Room in a second level Children’s Hospital and the ones during an extraordinary event as the first month of the lockdown due to the Sars CoV 2 Pandemic in relation to types, sites and severity of Orthopaedic trauma, age, sex, and place in which the trauma occurred.Methods Authors compared retrospectively all children who had an access to the Emergency Room of Children Hospital Giovanni XXIII of Bari and then to Pediatric Orthopedic Unit during the first month of lockdown due to the Sars CoV 2, from March 10th 2020 to April 10th 2020, with the children that had an access to the same hospital from March 10th 2019 to April 10th 2019 for the sites, the types and the severity of the Orthopedic injuries.Results In 2019 there were 261 accesses to Emergency Room, in 2020 69: during lockdown the reduction was of 75%.The data were statistically significant about: the age, lower in 2020 during lockdown, (p<0.0001) and the worst prognosis of the lesions in the same period, 42.65% of fractures versus 28.05% (p<0003). No statistical evidence about sex, anatomical site of trauma and kind of lesion.Conclusions The volume of the accesses for trauma during lockdown decreased by 75%; this means that to avoid the potential risk of Covid’s infection in Hospital, only children with major trauma were brought there by parents, while the ones with contusions and sprains remained at home.
