Gender-Based Variations In Hemodynamic Characteristics And Power Doppler Ultrasound Indices In Developmental Dysplasia Of The Hip (DDH)

Abstract

Background: The arterial vascularity of the hip has been investigated in normal infants using power Doppler sonography. This study addressed the differences in hip vascularity in infants with respect to gender and acetabular morphology.

Objective: To determine whether there is a relationship between the infant gender in hemodynamic characteristics and power doppler ultrasound indices in developmental dysplasia of the hip (DDH)

Materials and methods: 90 hips left and right (45patients) were enrolled in the study with gray-scale and power doppler ultrasound. The patients were referred have abnormal clinical hip examination and  had risk factors for developmental dysplasia of the hip. The infants ranged in age from 6 weeks to16 weeks. There were 20 boys and 25 girls.

Results: This study establishes a valuable foundation for understanding the relationship between Power Doppler ultrasound parameters and gender in infants with hip developmental dysplasia. The gender-specific differences in PD parameters, as well as the relationship between PD parameters and acetabular morphology, provide valuable insights into DDH's vascular characteristics. These findings suggest that PD ultrasound could be used not only as a diagnostic tool, but also to monitor disease progression and guide treatment decisions in DDH

Conclusion: There is a direct linear relationship between power doppler indices and gender infant hip. Female infants have a higher average PDUS indices than male infants. Power Doppler ultrasound and vascularity intensity in abnormal neonatal hips vary based on the anatomical region being evaluated. This observation deserves further investigation into its role in the physiological pathogenesis of neonatal hip disorders.
