“…All the individual US parameters evaluated in the first 3 months of life also showed close correlations with the overall radiographic parameters evaluated at 1 year of life. This finding is similar to those of many other studies, which also identified a close correlation between US and radiographic findings [10][11][12][13][14]17].…”

“…Studies have suggested high rates of false positives, and that a significant proportion of cases of "ultrasoundpositive DDH" may spontaneously resolve without treatment [25,27,28]. Additionally, missed or late presentations of DDH were still prevalent despite US screening [10,17]. The current literature, therefore, contains varying opinions on the correlation between US and subsequent radiographic findings for patients with DDH, with some studies concluding that there was no significant positive correlation between the two [10][11][12][13][14][15][16][17][18].…”

“…Some papers evaluated the NPV of US findings, and Table 3. Correlations, sensitivity, specificity, PPV, NPV, and accuracy of ultrasonographic findings when compared to the position of the femoral head at 1 year of life Ultrasonography 39(1), January 2020 e-ultrasonography.org therefore determined that some cases of dysplasia were not detected by ultrasound examinations, while others evaluated the statistical correlations between the parameters [10][11][12][13][14][15]17,18]. Through the current study, it can therefore be concluded that there is indeed a close correlation between the US findings and the radiographic findings, but the NPV is not perfect.…”

“…Owing to the developmental and wide-ranging nature of this condition, multiple imaging modalities have been utilised to screen for and to diagnose DDH across the various phases of a child's life. However, there exist varying opinions in the current literature regarding the correlation between ultrasonographic (US) and subsequent radiographic findings for patients with DDH, with some studies concluding that there was no significant positive correlation between the two [10][11][12][13][14][15][16][17][18].…”

Purpose: The study aimed to investigate the utility of ultrasonographic (US) findings in predicting the subsequent radiographic parameters of developmental dysplasia of the hips. Methods: In this 12-year retrospective cohort study, all newborn infants with a positive clinical examination or risk factors were included. They were scheduled for hip ultrasonography in the first 3 months, and subsequent radiographs at 1 year of life. The US images were evaluated using the Graf classification, Harcke's dynamic screening method, and Terjesen's femoral head coverage method. The radiographic images were evaluated using the acetabular index and femoral head position. The overall US or radiographic findings were considered abnormal if they were classified as abnormal for any of their respective parameters. The overall US and radiographic parameters were correlated. Results: A total of 160 patients were included. The overall US and radiographic parameters showed no statistically significant difference (P=0.050). The sensitivity, specificity, and accuracy of the overall US parameters were 57.1%, 84.9%, and 81.3%, respectively. All three individual US parameters showed no statistically significant differences, with the overall radiographic findings and acetabular index (P>0.05). However, they showed a statistically significant difference, with the position of the femoral head (P<0.001), with the US parameters having an excellent negative predictive value of 100% for identifying an abnormal femoral head position. Conclusion: The current study suggests that US findings evaluated in the first 3 months of life showed no statistically significant difference with radiographic findings evaluated at 1 year of life. The US parameters showed an excellent negative predictive value for abnormal femoral head position on radiographs.

Objectives This study investigated the progression of pubofemoral distance (PFD) with age and assessed the correlation between PFD and late acetabular index (AI) measurements. Methods This prospective observational study was conducted between January 2017 and December 2021. We enrolled 223 newborns who underwent the first, second, and third hip ultrasounds, and pelvis radiograph at a mean age of 18.6 days, 3.1 months, 5.2 months, and 6.8 months, respectively. The difference between PFD measured at serial ultrasounds and the correlation with AI were analyzed. Results The PFD increased significantly (p < 0.001) at serial measurements. The mean PFD at the first, second, and third ultrasounds were 3.3 (2.0–5.7), 4.3 (2.9–7.2), and 5.1 (3.3–8.0) mm, respectively. The PFD at three ultrasounds were all significantly (p < 0.001) and positively correlated with AI, with the Pearson correlation coefficients being 0.658, 0.696, and 0.753 for the first, second, and third ultrasounds, respectively. Using AI as reference, the diagnostic ability of PFD was calculated by the areas under the receiver operating characteristic curve, which was 0.845, 0.902, and 0.938 for the first, second, and third PFD, respectively. For the first, second, and third ultrasounds, PFD cutoff values of ≥ 3.9, ≥ 5.0, and ≥ 5.7 mm, respectively, yielded the greatest sensitivity and specificity in predicting late abnormal AI. Conclusion The PFD naturally progresses with age and is positively correlated with AI. The PFD has potential for predicting residual dysplasia. However, the cutoff for abnormal PFD values may require adjustment according to the patient’s age. Key Points • The pubofemoral distance measured in hip ultrasonography naturally increases as the infant’s hips mature. • The early pubofemoral distance demonstrates a positive correlation with late acetabular index measurements. • The pubofemoral distance may help physicians predict abnormal acetabular index. However, the cutoff for abnormal pubofemoral distance values may require adjustment according to patient’s age.
