Abstract:

Objective　To evaluate the clinical value of combined Graf and Harcke ultrasonography in early diagnosis and therapeutic effect evaluation of infant developmental dysplasia of the hip (DDH). Methods　The clinical data of 120 children (240 hips) with high risk of DDH within 6 month-old of age in Children's Hospital Affiliated to Zhengzhou University from January 2017 to February 2023 were collected. There were 54 boys and 66 girls, aged 1 to 6 (2.53±0.68) months. Graf and Harcke methods were used to evaluate the development and stability of hip joint. X-ray reexamination was performed for the treated children after 1 year-old of age, and the DDH treatment effect was evaluated by the International Hip Dysplasia Institute (IHDI) classification. Results　A total of 24 hip joints (10.00%, 24/240) were found to be suspicious abnormal in the first ultrasound examination, and all of them returned to normal after 4 - 6 weeks. There were 76 abnormal hips [31.67% (76/240)], among which 12 hips were "unstable" with Graf Ⅰ type and 4 hips with Graf Ⅱa type. After 4 - 6 weeks, 14 cases returned to normal but 2 cases turned to Graf Ⅱb type and received surgical treatment. There were 43 hip joints with dysplasia and 17 hip joints with dislocation, which were treated with surgical intervention. All the treated 62 hips after 1 year-old of age turned to IHDI Ⅰ type by X-ray review, with a acetabular index of (25±2)°. Conclusion　The combined application of Graf and Harcke techniques to observe hip joint from static and dynamic angles, respectively, has high clinical value in screening DDH and evaluating the therapeutic effect.
