The medical community has recognized overweight as an epidemic negatively affecting a large proportion of the pediatric population. This study was performed to investigate the effect of overweight on the outcome of conservative treatment for distal radius fractures (DRFs) in children.

Researchers performed a retrospective study of children with closed displaced distal metaphyseal radius fractures. Closed reduction was initially performed; if closed reduction failed, surgical treatment was performed. Patients were followed up regularly after treatment, and redisplacement was diagnosed on the basis of imaging findings. Potential risk factors for redisplacement were collected and analyzed. In total, 142 children were included in this study

Results:
--The final reduction procedure failed in 21 patients, all of whom finally underwent surgical treatment.

--The incidences of failed final reduction and fair reduction were significantly higher in the overweight/obesity group than in the normal-weight group.

--During follow-up, 32 patients developed redisplacement after closed reduction and cast immobilization.

--The three risk factors associated with the incidence of redisplacement were overweight/obesity [odds ratio (OR), 2.149], an associated ulnar fracture (OR, 2.127), and a three-point index of more than 0.40 (OR, 3.272).

To summarize, being overweight raises the risk of weight loss failure and reduces the reduction impact. In this study, overweight children were two times more likely than normal-weight children to experience redisplacement. As a result, obese children could benefit from more rigorous clinical supervision and, potentially, a lower surgical intervention threshold.
