高频超声在先天性髋关节脱位早期诊断中的应用价值

目的探讨先天性髋关节脱位的超声表现及高频超声技术在诊断先天性髋关节脱位中的应用价值。方法选择我院就诊的先天性髋关节脱位患儿125例,同期随机选取正常儿50例,应用高频超声检查髋关节,包括髋臼窝外形、髋臼骨性缘、软骨纤维肾唇及α,β角,分析这些指标在先天性髋关节脱位组与正常对照组间的差异。结果 125例先天性髋关节脱位患儿的超声检查正确诊断105例,漏诊15例,误诊5例。结论高频超声能较好地显示先天性髋关节脱位的形态学表现,可为临床提供较可靠地诊断依据,其无创、价廉及可重复性操作为先天性髋关节脱位的诊断及预后判断提供一种好的途径,值得推广。

Application of high frequency ultrasonographic diagnosis in congenital dislocation of the hip

Objective： To study the ultrasonic image features of Congenital dislocation of the Hip and the value of high frequency ultrasonography in diagnosing Developmental Dysplasia of The Hip. Methods： 125 patients with Congenital dislocation of the Hip were enrolled , another 50 healthy cases were selected as normal control. With high frequency ultrasonographic we checked the hip. Compared the difference of the hip in two groups. Results： In 125 cases , 105 cases were confirmed, 15 cases were missed and 5 cases were misdiagnosed. Conclusion ： High Frequency Ultrasonography can invasively show lesions of Congenital dislocation of the Hip. It is a very useful method to demonstrate Congenital dislocation of the Hip.
