Summary
This study establishes a reproducible method to measure normal web height in children, crucial for assessing web creep after syndactyly surgery. This technique aids in evaluating surgical outcomes and comparing different treatment approaches.
Area of Science:
- Hand surgery
- Pediatric orthopedics
- Radiographic analysis
Background:
- Web creep is a frequent complication after syndactyly release surgery.
- Objective measurement of normal web height is lacking, hindering accurate assessment of web creep.
- Standardized data is needed to evaluate surgical outcomes for syndactyly release.
Purpose of the Study:
- To develop a reproducible technique for measuring web height.
- To define the standard web height in a control pediatric population.
- To provide a baseline for evaluating web creep post-syndactyly surgery.
Main Methods:
- Evaluated 437 posteroanterior hand X-rays from children without upper extremity pathology.
- Measured web height as a ratio to digital length using defined landmarks.
- Analyzed data based on gender, age, and web space, assessing measurement reliability.
Main Results:
- The measurement technique demonstrated high reliability with no significant intraobserver or interobserver differences.
- Web height was consistent between genders but varied significantly with age and web location.
- Normal ranges for web height were established and graphically represented for different ages and web positions.
Conclusions:
- A reliable method for measuring pediatric web height was developed.
- Normal web height varies by age and web space location.
- This technique enables objective evaluation of web creep and comparison of surgical interventions for syndactyly.
