A cross-sectional study on the impact of the prevention and control response of the COVID-19 pandemic on minor's orthopedic trauma in Shanghai.

backgroundThe Chinese government has taken strong prevention and control measures against the COVID-19 pandemic. Although the pandemic is far from over, it has been effectively controlled in China. The outbreak of COVID-19 pandemic provides an opportunity to study the influence of governmental prevention and control response on orthopedic trauma in minors.

methodsWe collected and reviewed data and information on minor's orthopedic trauma from 1 January to 30 June of the past three year (2018, 2019 and 2020). The data were divided according to the time of prevention and control response level in 2020 (the first level response is from January 24 to March 22, the second level response is from March 23 to May 7, and the third level response is May 8 to now). By comparing the relevant data from orthopedic emergency and operating rooms from the past three years, the influence of governmental pandemic prevention measures on orthopedic trauma in minors was analyzed.

resultsA total of 36,301 minors were included in the study cohort. Before the prevention and control response, the data of the orthopedic emergency department of National Children Medical Center (Shanghai) in 2020 was the same as the previous two years. The condition of children undergoing surgery at the time of injury is significantly different under different levels of prevention and control response. Under the first-level response, the number of fractures, open injuries, radial head subluxation, and surgery were significantly reduced, and the severity of patients with surgery was also significantly reduced. Under the second-level response, the number of operations began to increase, and the severity of the disease also began to rise. Under the third-level response control, the number of fractures, open injuries, and operations have returned to the levels of the previous two years. The severity of the operation has also returned to its previous level. The number of subluxations of the radial head is still different from before.

conclusionThe prevention and control response for the pandemic of COVID-19 can reduce the incidence of orthopedic trauma in minors by strengthening the guardian's care and restricting children's outdoor activities. With the control of the pandemic, the amount of orthopedic trauma in minors will not be affected by low-level prevention and control.
