Insights
Most pediatric multiple fractures affect one region, but cross-regional injuries are significant. Understanding these pediatric fracture patterns aids in developing targeted prevention strategies.
Area of Science:
- Pediatric Orthopedics
- Epidemiology
- Trauma Surgery
Background:
- Multiple pediatric fractures present a significant public health challenge.
- Understanding the epidemiological characteristics and injury patterns is crucial for effective prevention and treatment.
Purpose of the Study:
- To evaluate the epidemiological features of multiple pediatric fractures.
- To identify specific injury patterns in children with multiple fractures.
Main Methods:
- Retrospective cross-sectional study of pediatric patients with multiple fractures (2016-2024).
- Fractures categorized into six anatomical regions.
- Hierarchical clustering on principal components (HCPC) used to identify injury patterns.
Main Results:
- 1950 children with multiple fractures analyzed; 65% were boys, median age 8.7 years.
- Ground-level falls (36.3%) were the most common injury mechanism.
- Single-region fractures (77.2%) predominated, but multi-region fractures (22.8%) showed distinct age and mechanism profiles.
- HCPC identified five distinct injury patterns, including Lower Limb-Foot and Craniofacial-Traffic Accident.
Conclusions:
- While most pediatric multiple fractures involve a single region, multi-region fractures require attention.
- Identifying specific pediatric fracture patterns is essential for targeted preventive strategies.
Objective:
This study aims to evaluate the epidemiological features of multiple pediatric fractures and identify specific injury patterns.
Methods:
This cross-sectional study retrospectively analyzed medical records for children with multiple fractures who presented to Children's Hospital of Nanjing Medical University between 2016 and 2024. Fractures were categorized into six anatomical regions: Craniofacial, Trunk/Pelvis, Upper Limb, Lower Limb, Hand, and Foot. Patients were divided into single-region and multi-region groups based on the number of affected regions. Hierarchical clustering on principal components (HCPC) was applied to explore potential injury patterns.
Results:
Among the 1950 children with multiple fractures, 65.0% were boys, with a median age of 8.7 years (4.8-12.3 years). The primary mechanisms of injury included ground-level falls (36.3%), traffic accidents (13.8%), and play/sports activities (10.8%). Single-region fractures accounted for 77.2%, while multi-region fractures accounted for 22.8%. There were statistically significant differences in age and injury mechanism distributions between the two groups (p < 0.001). In the single-region group, children aged 6-11 years predominated, with ground-level falls being the most common cause (44.4%) primarily resulting in upper limb fractures (74.4%). The multi-region group had a higher representation of adolescents aged 12-17 years, with traffic accidents as the primary cause and injuries mainly involving the lower limbs (63.5%), trunk (56.8%), and upper limbs (50.5%). HCPC identified five distinct injury patterns: Lower Limb-Foot, Trunk/Pelvis-High Fall, Upper Limb-Hand, Craniofacial-Traffic Accident, and Upper Limb-Trunk/Pelvis patterns.
Conclusion:
Most pediatric multiple fractures involve a single anatomical region; however, the burden of cross-regional fractures should not be overlooked. Identifying potential injury patterns is crucial for developing targeted preventive strategies.
