| Abstract_FL | Objective:To explore the feasibility of using magnetic resonance imaging (MRI) to measure the teardrop and sourcil line (TSL) for predicting the occurrence of residual acetabular dysplasia (RAD) after closed reduction (CR) in children with developmental dysplasia of the hip (DDH).Methods:This study measured and recorded the continuity of the bony TSL and the maximum acetabular distance (AD) on MRI in 54 children, totaling 68 hips (40 unilateral cases and 14 bilateral cases) clinically diagnosed with DHH and who underwent CR.X-ray images were used to observe and record the acetabular index (AI) at the time of CR, as well as the International Hip Dysplasia Institute (IHDI) classification.According to the modified Severin classification, the affected hips were divided into RAD and non-RAD groups, and differences between the two groups were compared.Additionally, patients were categorized into MRI-bony TSL continuous and non-continuous groups to compare differences in indicators between these groups.The receiver operating characteristic curve (ROC) was used to evaluate the effectiveness of the AD difference in predicting the occurrence of RAD.Results:Among the 68 hips, 2 were classified as Severin type Ⅰ, 15 as type Ⅱ, 46 as type Ⅲ, and 5 as type Ⅳ; 51 hips in the RAD group, and 17 in the non-RAD group.Univariate analysis showed that IHDI classification, the continuity of the bony TSL, and the AD difference between the normal and affected sides were related factors for the occurrence of RAD after CR in DHH children.Multivariate logistic regression analysis revealed that IHDI classification (
OR=0.090, 95%
CI: 0.010-0.794), MRI-bony TSL continuity (
OR=0.015, 95%
CI: 0.002-0.128), and AD difference between the normal and affected sides (
OR=7.1×10
8, 95%
CI: 370.6-1.4×10
15) were independent factors influencing the occurrence of RAD after CR in DHH children (
P<0.05).ROC curve analysis showed that the difference between normal side and affected side AD predicted the onset of RAD by 0.31cm, corresponding sensitivity and specificity were 0.900 and 0.833, respectively, and AUC was 0.917.
Conclusions:IHDI classification, MRI-bony TSL continuity, and the AD difference between the normal and affected sides can serve as indicators for predicting RAD occurrence after CR in DDH children.Compared to X-ray TSL, MRI-bony TSL can predict the occurrence of RAD earlier and more accurately. |
