Abstract:
Objective To investigate the relationship between asymmetry of skin folds around the hip and developmental dysplasia of the hip(DDH).Methods A retrospective analysis was performed on 308 infants who underwent DDH screening at Xuzhou Children's Hospital Affiliated to Xuzhou Medical University from January 2017 to December 2022.According to screening reasons,they were divided into observation group(simple asymmetry of skin folds around the hip,n=116),clinical abnormality group(clinical manifestations such as hip snap,limited hip abduction,unequal length of lower limbs,n=92)and control group(simple hip screening,n=100).Clinical evaluation results and Graf hip ultrasonography results were analyzed,and the detection rate of pathological DDH in each group was compared.The positive predictive value,negative predictive value,sensitivity and specificity of pathological DDH were calculated.Results Five cases(4.31%)were detected as pathological DDH in observation group.Twenty-eight cases(30.43%)were detected as pathological DDH in clinical abnormality group.Four cases(4.00%)were detected with pathological DDH in control group.There was no significant difference in detection rate of pathological DDH between observation group and control group(χ2=0.909,P=0.592).The detection rate of pathological DDH in clinical abnormal group was significantly higher than that in control group(χ2=24.109,P<0.001).The positive predictive value,negative predictive value,sensitivity and specificity of asymmetry of skin folds around the hip for pathological DDH were 4.31%,96.00%,55.56%and 46.38%,respectively.The positive predictive value,negative predictive value,sensitivity and specificity of abnormal clinical manifestations for pathological DDH were 30.43%,96.00%,87.50%and 60.00%,respectively.Conclusion clinical signs to guide imaging screening of infants.
