Clinical Scorecard: Creation and external validation of a predictive model for unsuccessful closed reduction in pediatric supracondylar humerus fractures: a multicenter retrospective analysis

At a Glance

Key Highlights

• 34.1% of patients required conversion to open reduction after attempted closed reduction.
• Model demonstrated good discrimination (AUC = 0.842) in the development cohort.
• External validation showed acceptable discrimination (AUC = 0.727).
• Calibration indicated good agreement between predicted and observed risks.
• Decision curve analysis suggested potential clinical utility for preoperative planning.

Guideline-Based Recommendations

Diagnosis

• Use preoperative radiographic findings to assess fracture characteristics.

Management

• Consider predictors for failed closed reduction to guide surgical planning.

Monitoring & Follow-up

• Monitor neurovascular status preoperatively, especially in cases with compromised perfusion.

Risks

• Be aware of risks associated with repeated closed reduction attempts, including soft tissue injury and neurovascular compromise.

Patient & Prescribing Data

Pediatric patients with Gartland type III extension-type SCHF.

Standard treatment involves CRPP, with consideration for open reduction if closed reduction fails.

Clinical Best Practices

• Perform preoperative neurovascular assessments routinely.
• Limit closed reduction attempts to minimize risks in cases with concerning perfusion.
• Utilize the predictive model for preoperative risk stratification.
