Abstract：Objective To investigate the value of ultrasound in screening infantile developmental dysplasia of the hip(DDH),the ultrasonic image characteristics of hip joint,and correlation of various ultrasonic measurement parameters.Methods The clinical data of 8 149 infants who received bilateral hip joint examination in Xi'an People's Hospital from January 2021 to March 2022 were retrospectively collected.All infants underwent ultrasound examination.The incidence of DDH was analyzed,and the infants were divided into normal group and abnormal group according to the presence or absence of DDH.The hip α angle,β angle and femoral head coverage(FHC)were compared between the two groups.The hip αangle,β angle,and FHC were analyzed in different gender,pathogenic sites,skin lines,and age in the abnormal group,and the correlation of hip α angle,β angle,and FHC was discussed.Results Among 16 298 hip joints of 8 149 infants,79(4.84‰)were abnormal,which were defined as the abnormal group,and the remaining 16 219 were defined as the normal group.α angle and FHC of the normal group were larger than those of the abnormal group,and β angle was smaller than that of the abnormal group,with statistically significant difference(P＜0.01).According to statistical analysis,the incidence of DDH was higher in female infants than in male ones,and higher in the left hip joint than in the right one,higher in infants with asymmetric skin lines than in infants with symmetric skin lines,and higher in 0-2 month-old infants than in＞2-4 month-old and＞4-6 month-old ones,with statistically significant difference(P＜0.01).Spearman correlation analysis found that α angle was positively correlated with FHC,and negatively correlated with β angle.β angle was negatively correlated with α angle and FHC.FHC was positively correlated with α angle and negatively correlated withβ angle(P＜0.05).Conclusion Compared with infants with normal hip joint development,the ultrasonic image characteristics of infants with DDH are significantly different,and there are correlations among various ultrasonic measurement parameters.Ultrasound can provide scientific reference for clinical screening of DDH.
