Fractures of the radial head and associated elbow injuries in children

Area of Science:

• Orthopedic Surgery
• Pediatric Traumatology
• Musculoskeletal Injuries

Background:

• Radial head fractures are common in pediatric elbow injuries.
• Understanding associated injury mechanisms and prognostic factors is crucial for effective treatment.

Purpose of the Study:

• To analyze the mechanism of injury in pediatric radial head fractures.
• To identify unfavorable prognostic factors influencing treatment outcomes.
• To evaluate different treatment modalities for these fractures.

Main Methods:

• Retrospective analysis of 37 pediatric patients treated at Nancy Children's Hospital.
• Assessment of injury mechanisms, including valgus strain, compression, and distraction forces.
• Evaluation of treatment outcomes (conservative, closed intramedullary pinning, open reduction) and associated injuries.

Main Results:

• A valgus strain with compression and distraction forces was the primary injury mechanism.
• 76% excellent or good results were achieved at an average 2-year follow-up.
• Conservative treatment was effective for minimally displaced fractures.
• Closed intramedullary pinning (CIMP) showed high success rates, with only three failures in severely displaced fractures.
• Open reduction yielded poor results, with 88% fair/poor outcomes associated with olecranon fractures.

Conclusions:

• Minimally displaced radial head fractures in children can be effectively managed conservatively.
• Closed intramedullary pinning (CIMP) is a viable surgical option for severely displaced fractures.
• Open reduction should be avoided due to poor outcomes, particularly when associated with olecranon fractures.
• Key unfavorable prognostic factors include severe displacement, associated injuries, inadequate reduction, and open reduction techniques.
