Insights
Obese children aged 8-12 with supracondylar humerus fractures are over 4 times more likely to need open reduction internal fixation (ORIF). This finding highlights increased surgical complexity for pediatric fracture management in older obese children.
Area of Science:
- Pediatric Orthopedics
- Trauma Surgery
- Public Health
Background:
- Childhood obesity is a growing concern in the U.S.
- Obesity impacts fracture complexity, treatment, and outcomes in children.
- This study investigates the link between obesity and surgical management of humerus fractures in children.
Purpose of the Study:
- To determine if obese children with supracondylar humerus fractures require open reduction internal fixation (ORIF) more often than nonobese children.
- To analyze the association between obesity and surgical intervention for pediatric supracondylar humerus fractures.
Main Methods:
- Utilized the 2003-2012 Kid's Inpatient Database for pediatric supracondylar humerus fractures (ICD-9, 812.41) in children aged 2-12.
- Categorized patients by surgical approach: closed reduction percutaneous pinning (CRPP) or open reduction internal fixation (ORIF).
- Employed univariable and multivariable logistic regression to assess the impact of obesity on ORIF, with P<0.05 considered significant.
Main Results:
- Analyzed 31,905 pediatric supracondylar humerus fractures; 105 (0.3%) patients were obese.
- Obesity was associated with increased odds of ORIF, particularly in children aged 8-12.
- Obese children aged 8-12 were significantly more likely to undergo ORIF (OR, 4.29; 95% CI, 1.78-10.36) compared to normal-weight peers.
Conclusions:
- Obese children aged 8-12 with supracondylar humerus fractures are over 4 times more likely to require ORIF.
- Healthcare providers should counsel older obese children and families on potential surgical complexities.
- Early identification and management strategies are crucial for optimizing outcomes in this patient group.
Background:
As childhood obesity remains an ongoing issue for the United States there has been an increasing number of studies detailing its effect on fracture complexity, management, and outcomes. This study utilizes a national database to examine whether obese children with supracondylar humerus fractures are more likely to require open reduction and internal fixation than nonobese children.
Methods:
The Healthcare Cost and Utilization Project Kid's Inpatient Database of 2003, 2006, 2009, 2012 were queried for pediatric supracondylar humerus fractures [International Classification of Disease (ICD-9), 812.41] between 2 and 12 years. Patients were separated into those undergoing closed reduction percutaneous pinning (CRPP), open reduction internal fixation (ORIF), or both. Obesity was determined by comorbidity and ICD-9 coding (ICD-9, 278.00, 278.01). Univariable and multivariable logistic regression models were utilized with P<0.05 considered significant.
Results:
Between 2003 and 2012, 31,905 patients between the ages of 2 and 12 years sustained supracondylar humerus fractures. In total, 105 patients (0.3%) were obese. A majority of patients, 27,658 (86.7%), underwent CRPP. Odds for ORIF increased in association with age, obesity, white race, and private insurance. Significant association was found between age and obesity (P<0.05) in those undergoing ORIF. Obese children between 2 and 7 years of age had no difference in ORIF or CRPP compared with normal-weight children. Those between 8 and 12 years who were obese were significantly more likely to undergo ORIF (OR, 4.29; 95% confidence interval, 1.78-10.36).
Conclusions:
Supracondylar humerus fractures sustained in obese children between 8 and 12 years are over 4 times more likely to require ORIF compared with normal-weight children of the same age. Providers should identify and counsel older obese children and their families regarding the potential for increased difficulty in fracture management that may require open surgical intervention.
Level Of Evidence:
Level IV-case series.

01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
