Obesity and Failure of Nonsurgical Management of Pediatric Both-Bone Forearm Fractures.

PURPOSE: In pediatric extremity fractures treated nonsurgically, maintaining reduction can be difficult in obese children owing to the larger soft tissue envelope. The purpose of this study was to investigate the relationship between obesity and failure of nonsurgical management of pediatric both-bone forearm fractures.

METHODS

We conducted a retrospective review of 129 skeletally immature patients older than 2 years who received nonsurgical treatment for closed radius and ulna shaft fractures at a level I pediatric trauma center between 2011 and 2014. The patients were divided into 2 groups: (1) normal-weight children and (2) overweight and obese children. The primary outcome measure was failure of nonsurgical management, defined as the indication for repeat closed reduction under anesthesia or surgical intervention owing to unacceptable angulation after initial closed treatment.

RESULTS

Of the 129 patients included in the study, 34 patients (26%) were female and 95 patients (74%) were male. Seventy-six patients (59%) were normal weight, 27 patients (22%) were obese, and 26 patients (20%) were overweight. Eighteen percent (14 of 76) of normal-weight children failed nonsurgical management compared with 34% (18 of 53) of overweight and obese children. Twenty-nine percent (4 of 14) of normal-weight children who failed nonsurgical management required surgery compared with 56% (10 of 18) of overweight and obese children.

CONCLUSIONS

Overweight and obese children have a significantly higher rate of failure of nonsurgical management of both-bone forearm fractures compared with normal-weight children. These patients may benefit from closer clinical follow-up and a lower threshold for surgical intervention.

TYPE OF STUDY/LEVEL OF EVIDENCE: Prognosis II.
