    Area of Science:

    • Orthopedics
    • Pediatric Orthopedics
    • Growth and Development

    Background:

    • Leg length discrepancy is a common pediatric orthopedic issue.
    • Accurate prediction of growth is crucial for effective management and surgical planning.

    Purpose of the Study:

    • To present a novel graphic method for recording and interpreting leg length discrepancy data.
    • To provide a tool for predicting future growth, considering growth percentile and growth inhibition.
    • To evaluate the accuracy of this method in predicting surgical outcomes.

    Main Methods:

    • Development of a straight-line graph method for data analysis.
    • Incorporation of child's growth percentile and degree of growth inhibition into predictions.
    • Application of the method to predict effects of corrective surgical procedures.
    • Comparison with the growth-remaining method using case studies.

    Main Results:

    • The straight-line graph method offers a mechanism for predicting future growth.
    • It accurately accounts for growth percentile and growth inhibition.
    • The method demonstrated significantly higher accuracy than the growth-remaining method in predicting outcomes, especially with growth inhibition.

    Conclusions:

    • The presented graphic method enhances the accuracy of predicting leg length discrepancy progression.
    • It is a valuable tool for surgical planning and timing in pediatric orthopedic cases.
    • This method offers a superior alternative to traditional approaches, particularly in complex cases.
