目的 :对比分析小儿发育性髋关节发育不良X线检查与超声检查的诊断价值。方法 :选择2010年2月~2015年12月在我院进行诊治的发育性髋关节发育不良患儿80例,比较X线检查和超声检查的诊断符合率,超声Graf法诊断的特异度、敏感度、符合率、阴性预测值和阳性预测值。结果 :超声检查的诊断符合率为88.75%,明显高于X线检查的67.50%;超声Graf法诊断发育性髋关节发育不良特异度、敏感度、符合率、阴性预测值和阳性预测值分别为100.0%、86.9%、92.5%、83.5%和100.0%。结论 :小儿发育性髋关节发育不良超声检查比X线更加准确,具有较高的诊断价值,值得应用推广。
OBJECTIVE: To compare the diagnostic value of X-ray and ultrasonography in the development of pediatric hip dysplasia. Methods: Totally 80 children with developmental dysplasia of hip dysplasia diagnosed and treated in our hospital from February 2010 to December 2015 were selected. The diagnostic coincidence rate of X-ray examination and ultrasonography, the specificity and sensitivity of ultrasonic Graf method were compared Degree, coincidence rate, negative predictive value and positive predictive value. Results: The diagnostic coincidence rate of ultrasound examination was 88.75%, which was significantly higher than that of X-ray examination (67.50%). The specificity, sensitivity, coincidence rate, negative predictive value and positive predictive value of Graf method in diagnosing developmental hip dysplasia were 100.0%, 86.9%, 92.5%, 83.5% and 100.0%. Conclusion: Ultrasonic examination of PDD in children is more accurate than X-ray, which is of high diagnostic value and worthy of promotion.
