Epidemiology and treatment of pediatric tibial fractures in Sweden: a nationwide population-based study on 5828 fractures from the Swedish Fracture Register

Abstract

PurposePediatric tibial fractures have been described internationally as mainly caused by fall during leisure activities and organized sports and showing a higher incidence in boys. Still, most studies are single center studies or have a small sample size. This study aimed to analyze sex and age distribution, seasonal variation, injury mechanisms and treatment of pediatric tibial fractures based on the nationwide Swedish Fracture Register (SFR).MethodsAll tibial fractures in patients < 16 years at injury and registered in 2015–2019 were extracted from the SFR. We analyzed patient characteristics such as sex and age, injury mechanism, fracture location and treatment.ResultsThe study cohort consisted of 5828 pediatric tibial fractures in 5719 patients. Median age of the patients was 7 years and 58% were boys. Shaft fractures were most common, followed by the distal and proximal tibia. The lowest incidence was observed during autumn. The most common cause of injury was fall mostly involving winter sports, stumbles and fall from play equipment. Play/free time and sports were the most common activities, common places of injury were sports facility and home. 1% were open fractures. 78% were treated non-surgically. Screw fixation was performed in 52% of surgically treated fractures, predominantly in the distal segment.ConclusionInjury mechanism differs between age groups; play/free time injuries are common in younger children compared with sport activities in older children. Most patients are treated non-surgically. Open fractures are rare. Information on injury patterns is useful working preventively, for example safety work in playgrounds.
