Study on multiplanar measurements of infant hips with three‐dimensional ultrasonography

Abstract

Purpose An automatic evaluation technology based on artificial intelligence and three‐dimensional ultrasonography (3D US) is proposed for hip US inspection plane selection. This study aimed to evaluate the consistency of the α angle as measured using 3D US to select the section plane and two‐dimensional ultrasonography (2D US) to manually select the Graf image, as well as to explore the feasibility of diagnosing developmental dysplasia of the hip (DDH) using 3D US and reconstruction technology. Methods A total of 216 infant hips were included and assessed by doctors using 3D US layer‐by‐layer. The researchers used a computer to identify the coronal images that met the Graf standard and then compared the αX values obtained with the αG values measured artificially by 2D US. Results Compared with 2D US, 3D US more clearly showed the relative positions of the ilium, ischia, and pubis. The measured α value of the optimal section obtained by 3D US showed good agreement with the measured α value of the standard Graf section. Conclusion The artificial intelligence and 3D US‐based automatic evaluation technology for section selection and inspection for DDH showed good agreement with the Graf method based on standard sections.

Study on the efficacy of brace therapy for developmental dysplasia of the hip with Graf IIc and greater severity

“…In our opinion, the braces had better efficacy for infants who were younger 'at the beginning of treatment', reaching 87.0% in the '≤42 days' group. After a treatment age of more than 120 days, effective rates were only 45-65%, consistent with previous studies that use was most effective before 6 weeks of age [39]. Early brace treatment is recommended.…”

Analysis of the results of hip ultrasonography in 48 666 infants and efficacy studies of conservative treatment

“…The shortcomings of this study are that, due to the retrospective nature of the study, the medical history data were not complete enough to analyze certain risk factors associated with the occurrence of DDH more extensively, such as the fetal birth style of each infant, whether the child was the first child, and family history. At present, our team is advancing research on efficacy‐related factors and ultrasound multiplane measurements 30 . In the future, we hope to continue to carry out prospective research on DDH diagnosis and treatment and more accurate and in‐depth research on DDH.…”

In addition, the variable time point for US evaluation may have also affected the results.…”

Follow-up Value of Hip Medial Ultrasound in Infants and Children With Developmental Dysplasia of the Hip Treated With Reduction and Spica Casting

“…14,15 Ultrasonography can also be used for multisectional scanning to provide multiplanar visualization. 16,17 Our previous studies have assessed the accuracy of hip medial ultrasound with MRI. The sensitivity, specificity, positive predictive value, and negative predictive value of ultrasound for assessing hip reduction have been evaluated.…”

“…Ultrasonography is a noninvasive examination method that does not involve radiation exposure and can provide detailed imaging of the cartilage and soft tissues 14,15 . Ultrasonography can also be used for multisectional scanning to provide multiplanar visualization 16,17 …”
