Forecasting the flap: predictors for pediatric lower extremity trauma reconstruction

Area of Science:

• Orthopedic Surgery
• Pediatric Trauma
• Reconstructive Surgery

Background:

• Predicting the need for post-traumatic lower extremity reconstruction in children is difficult.
• Most research focuses on adult lower extremity reconstruction, leaving a gap in pediatric care.
• This study identifies risk factors for free flap reconstruction in pediatric lower extremity trauma.

Purpose of the Study:

• To evaluate predictive risk factors for free flap reconstruction in pediatric lower extremity trauma.
• To address the lack of specific data on reconstructive needs in pediatric trauma patients.
• To inform the development of a risk calculator for complex pediatric lower extremity reconstruction.

Main Methods:

• Retrospective chart analysis of pediatric patients (<18 years) with lower extremity wounds over a 5-year period.
• Review of patient demographics, trauma details, and operative information.
• Univariate and multivariate regression models used to identify predictors of free flap reconstruction.

Main Results:

• Out of 1,821 patients, 2.25% required free flap reconstruction.
• Older age (OR, 1.134), all-terrain vehicle accidents (OR, 6.698), and trauma team activation (OR, 2.443) were significant predictors.
• Free flap reconstruction was needed in 41 pediatric patients.

Conclusions:

• Older pediatric patients, those with all-terrain vehicle accidents, and trauma team activation cases show a higher likelihood of needing free flap reconstruction.
• Findings can aid in creating an early risk assessment tool for pediatric lower extremity reconstruction.
• This research highlights key factors for anticipating complex reconstructive needs in pediatric trauma.
