摘要

Purpose

The deep fascia plays a crucial role in musculoskeletal function, yet little is known about its characteristics in children. The current literature lacks reference values for deep fascia thickness in healthy pediatric populations, making assessing alterations in pediatric disorders difficult. This study aims to provide baseline measurements of deep fascia thickness in the lower limbs of healthy pediatric subjects using ultrasound and establish pilot reference data for future clinical applications.

Methods

This cross-sectional study included 21 healthy children aged 3–9 years. Ultrasound imaging was performed using a 17 MHz linear probe at two standardized locations on fascia lata and crural fascia. A modified imaging protocol ensured feasibility for pediatric subjects. Measurements were analysed using ImageJ, with inter-rater reliability assessed via the Intra-Class Correlation Coefficient (ICC). Statistical analyses, including correlations with age and BMI, were conducted using Jamovi software (p < 0.05).

Results

The mean fascia lata thickness was 0.802 ± 0.140 mm (anterior) and 1.34 ± 0.251 mm (lateral). The mean crural fascia thickness was 0.629 ± 0.084 mm (anterior) and 0.644 ± 0.076 mm (lateral). A statistically significant correlation was found only between BMI and lateral crural fascia thickness, whereas no significant correlations with age were observed. Inter-rater reliability was good (ICC 0.893, 95% CI 0.851–0.923).

Conclusion

This study provides the first reference values for pediatric deep fascia thickness. Lateral regions of fascia lata were thicker than anterior regions, consistent with adult findings. Ultrasound imaging proved to be a reliable and well-tolerated method for pediatric fascia evaluation, supporting its future use in research and clinical assessments.
