Objective To investigate the epidemiological characteristics of tibial shaft fractures and analyze the effect of COVID-19 on it.Methods We retrospectively analyzed the clinical data of 1037 patients with tibial shaft fractures treated in the Second Affiliated Hospital of Air Force military Medical University from January 2012 to December 2021,which accounting for 28.44% (1 037/3 646) of tibiofibular fractures in the same period.That including 765 males (73.77%) and 272 females (26.23%),with a male to female ratio of 2.81︰1,The average age was (40.91±18.99).The patients from January 2018 to December 2019 were assigned into pre-epidemic group,and those from January 2020 to December 2021 into post-epidemic group.The epidemiological characteristics of the patients were analyzed,such as sex,age,residence,cause of injury,fracture classification and so on.The differences of epidemiological characteristics between the two groups were analyzed and compared.Results Tibial shaft fracture mainly occurred in the age group of 41-50 years old in males and 31-60 years old in females (P<0.05).The main causes of tibial shaft fractures were traffic accident injuries (55.26%) and fall injuries (23.92%).According to the AO classification of tibial shaft fractures,the constituent ratio of 42-A was the highest (48.99%),followed by 42-B (26.71%),and 42-C (24.30%) was the least.After the epidemic of COVID-19,the number of tibial shaft fractures decreased,but the average age was higher than that before the epidemic,and there was no significant difference (P>0.05).There was no difference in the distribution of sex,residence,season,cause of injury and age between pre-epidemic group and postepidemic group (P>0.05).There were significant differences in the mode of admission,the condition at the time of admission and AO classification between the two groups(P<0.05).Conclusion Tibial shaft fractures accounted for 28.44% of tibiofibular fractures (1 037/3 646),and most of them were male.The main causes of tibial shaft fractures were traffic accident injury and fall injury.In the AO classification of tibial shaft fracture,42-A is the most common type.After the epidemic of COVID-19,the number of tibial shaft fractures decreased,which was mainly admitted to the hospital by emergency.The number of emergency and criticaly patients decreased.And the type 42-A fractures were more common.
