Background: Amputations in children represent significant events. Few studies analyse amputations in this specific population, and most of them are old, regionalised and with small sample sizes. Besides, there are no large studies in low-income and middle-income countries. This study aims to analyse a large sample of amputations (19 439 procedures performed in the Brazilian public health system) in children aged 0-14 over 14 years.
Methods: Retrospective cross-sectional population-based analysis of all lower limb amputations performed in the Brazilian public health system between 2008 and 2021 in children up to 14. Using a public database, all types of amputations were selected, defining the number of procedures, their main aetiologies, trends over the years, patient demographics and regional distribution.
Results: 19 439 lower limb amputations were performed in the Brazilian public health system between 2008 and 2021, mainly at the toe level (85%). Amputations occurred predominantly in males (64%) and children aged 0-4 (47%). The global trend is a non-significant decrease in the total number of amputations over the period (p=0.427), but we observe a significant decrease (p<0.001) in amputations in older children (aged 10-14). Amputations are more concentrated in the most populated regions, while the highest mortality is found in the least densely populated areas. Trauma is the main aetiology associated with lower limb amputations in Brazilian children (60%).
Conclusion: The epidemiology of amputations in Brazil differs from the rest of the world. Trauma is the main aetiology.
