The impact of obesity on pediatric orthopedic polytrauma patients

Objectives: The effect of obesity on fracture care and management in the adult population has been well documented in the literature; there is a scarcity of evidence-based research reporting the impact of obesity on pediatric orthopedic polytrauma patients. The aim of this study was to objectively investigate the impact of obesity on pediatric orthopedic polytrauma patients to optimize care and fracture management. Methods: A single-center retrospective cohort study of pediatric polytrauma patients aged 2–18 years old admitted to a level 1 trauma center was conducted over three years. Patients were categorized based on their body mass index (BMI). A logistic regression model was used to identify significant variables between the study groups. Results: A total of 60 patients were included in the analysis and divided into normal weight group (n = 36) and overweight/obese group (n = 24). A trend of lower injury severity score (ISS) was observed in the overweight/obese group compared to the normal weight group. Non-orthopedic injuries, including head, chest, and abdominal injuries, were found to be less in the overweight/obese group. Higher rates of spine and extremity fractures were reported in the overweight/obese group, as well as the need for surgical fixation (P = 0.05). No specific differences in complications, outcome, or discharge facility were found between the two groups. Conclusion: The paradoxical association between BMI and ISS/non-orthopedic injuries, in contrast to spine and extremity fractures, reflects the complex relationship between obesity and polytrauma patterns. Large multi-center prospective studies are needed to predict clinical outcomes in pediatric orthopedic polytrauma patients.
