小儿发育性髋关节发育不良X线检查与超声检查的对照研究

Comparative study of X-ray and ultrasound checking in diagnosis of developmental dysplasia of hip

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 investigate X-ray and ultrasound checking in diagnosis of developmental dysplasia of hip. Meth-ods Selected 80 cases of patients with developmental dysplasia of hip who were treated in our hospital from January 2010 to December 2015. Compare the diagnostic accordance rate of X-ray examination and ultrasound examination, the specific degree, sensitivity, coincidence rate, and negative predictive value and positive predictive value of ultrasonic Graf method. Results The diagnostic accordance rate of ultrasound was 88.75%, significantly higher than the the X-ray 67.50%; ultrasonic Graf method in the diagnosis of developmental dysplasia of the hip speciality rate, sensitivity and coincidence rate, negative predictive value and positive predictive value were 100.0%, 86.9%, 92.5%, 86.9% and 100.0%. Conclusion The ultrasound checking in diag-nosis of developmental dysplasia of hip has more accurately than X-ray, has high diagnostic value, which is worth popularizing application.
