DeFrancesco CJ, et al. - This retrospective cohort study was conducted to evaluate whether high body mass index (BMI) increased the risk of loss of reduction (LOR) after the closed reduction and casting for displaced concomitant radial and ulnar shaft fractures in pediatric patients. It was noted that attentive and frequent follow-up was warranted in the overweight and obese children with displaced concomitant fractures of the radial and ulnar shafts due to a high risk of LOR. The initial reduction in such patients, ought to be closely scrutinized, and for surgical fixation, a lower threshold could be considered.
