Purpose:
To evaluate whether axial dynamization (controlled motion) in external fixation improves healing outcomes versus static fixation in pediatric femur fractures.
Methods:
Randomized controlled trial of 53 femur fractures treated with either dynamic or static external fixation, assessing healing time and clinical outcomes.
Key Findings:
- No significant difference in early callus formation or radiographic healing time between groups.
- Fixator removal and return to full weight-bearing times were similar.
Conclusion:
Axial dynamization does not significantly accelerate healing or improve outcomes over static fixation in pediatric femur fractures.
What Does This Mean for Providers?
Static external fixation remains an effective and reliable treatment for pediatric femur fractures without need for dynamization protocols.
