高频超声与三维CT诊断婴幼儿发育性髋关节发育不良的对照观察

Control study of high-frequency ultrasound and three-dimensional computed tomography in diagnosis of developmental dysplasia of the hip in infant

目的观察超声诊断婴幼儿发育性髋关节发育不良的可行性及诊断价值。方法选取就诊于中国医科大学附属盛京医院临床怀疑发育性髋关节发育不良的门诊及住院患儿,月龄6～36个月,共42例患儿84髋。对所有患儿均参照Graf法行超声检查,并同时行三维CT检查。将超声检查结果与三维CT对照,评价分析超声诊断婴幼儿发育性髋关节发育不良的准确性。结果84髋中共检出正常髋关节28髋,髋关节发育不良12髋,髋关节半脱位15髋,髋关节完全脱位29髋。超声诊断DDH的准确度为97.62%。结论高频超声诊断婴幼儿发育性髋关节发育不良具有很高的临床实用价值,可以作为一种常规的检查方法。

Objective To observe the feasibility and value of ultrasound in diagnosis of developmental dysplasia of the hip （DDH） in infant. Methods A total of 84 hips of 42 infants aged 6 to 36 months who were suspected of DDH were included in this study. All patients were examined by ultrasonography with the Graf＇s method, and were scaned by three-dimensional computed tomography （3D CT）. The results of ultrasounogrphy were compared with that of 3D CT, and the availability of ultrasound in diagnosing DDH in infant was evaluated. Results Twenty-eight normal hips, 12 dysplasia hips, 15 subdislocation hips and 29 dislocation hips were diagnosed in the 84 hips. The accuracy of ultrasound in diagnosis of DDH was 97.62%. Conclusion High-frequency ultrasound scan is a valuable method in diagnosing the DDH in infants, and can be used as a routine diagnostic method.
