Background: Ankle fracture is one of the most frequent pediatric lower-limb fractures and may result in serious complications.
Objective: This study aimed to determine the epidemiology of ankle fractures, defining fracture types, treatments, and complications in a pediatric population below 16 years old.
Methods: Medical records of all the ankle fracture patients treated in our hospital during 2004-2020 were retrospectively reviewed. Data regarding age, sex, mechanism of injury, fracture type, treatment modalities, and complications were collected.
Results: We examined records involving 328 children with 331 ankle fractures, with a ratio of 1:2 male per female. Mean annual prevalence was 24.3 per 100,000 children. Mean patient age was 11.2 ± 4.2 years, with 75.3% of them aged over 10 years. Sports activities accounted for the largest percentage of fractures (162 cases; 49.4%), followed by falls (67; 20.4%) and road traffic accidents (37; 11.3%). Physeal fractures were the most frequent type of lesion (223 cases). Most ankle fractures (60%) were managed using closed reduction and casting; for the remaining 40% of cases, fracture fixation was performed after closed or open reduction to correct the articular step-off and ensure the anatomical restoration of the physis. The main ankle fracture complication was premature growth arrest (12.1% of all physeal fractures).
Conclusion: Pediatric ankle fractures primarily affect children older than 10 years. Most of these fractures were caused by sports injuries or low-energy trauma. The majority of these fractures are physeal, and the distal tibial physis is affected 10 times more frequently than the distal fibular physis.
Level of evidence: Level III.
