Clinical Report: Utilizing Three-Dimensional Virtual Surgical Planning for Correcting Lower Limb Deformities with Intramedullary Nails
Overview
This study evaluates the effectiveness of three-dimensional (3D) virtual surgical planning and patient-specific cutting guides in correcting complex lower-limb deformities using intramedullary nails (IMNs) in pediatric patients.
Background
Lower limb deformities can significantly impact mobility and quality of life, particularly in pediatric patients. Traditional correction methods have limitations, including discomfort and complications associated with external fixation. The adoption of intramedullary nails offers an alternative method for deformity correction.

Key Findings
3D virtual planning and patient-specific cutting guides were utilized for 21 patients.
Excellent correction was achieved in 83% of extremities.
The mean time to radiographic union was 8.5 weeks.
No major intraoperative or early postoperative complications were reported.
Two extremities (8.7%) experienced delayed union, which resolved without intervention.
Clinical Implications
The study presents findings on the use of 3D virtual surgical planning and patient-specific guides in pediatric patients undergoing lower limb deformity correction.
Conclusion
The findings support the effectiveness of 3D virtual surgical planning in managing complex lower-limb deformities with intramedullary nails.
