Abstract: Objective: To analyze the diagnostic value of Doppler ultrasound in pediatric hip dysplasia. Methods: A total of 70 cases of suspected developmental dysplasia of the hip (DDH) from March 2022 to March 2024 were selected. Three-dimensional CT was used as the diagnostic standard to evaluate the effectiveness of Doppler ultrasound. Results: Among the 70 subjects, 50 were confirmed to have DDH by three-dimensional CT. The sensitivity of ultrasound diagnosis was 94.00% (47/50), the specificity was 80.00% (16/20), and the accuracy was 90.00% (63/70). The anteroposterior, lateral, and vertical diameters in the DDH group were significantly lower than those in the normal group (P < 0.05). There was no significant difference in femoral head cartilage H/W ratio between the two groups, but the height and width of femoral head cartilage in the DDH group were significantly lower than in the normal group (P < 0.05). The detection rates of rounded or defective acetabular edges, shallow acetabular fossa, labrum located between the femoral head and acetabulum, blurred contours, and poor coverage of the femoral head by the acetabular roof were significantly higher in the DDH group than in the normal group (P < 0.05). Conclusion: Doppler ultrasound has high sensitivity and accuracy in diagnosing pediatric hip dysplasia, with key diagnostic indicators being the morphology of the femoral head cartilage and the ossification center of the femoral head.
