高频超声在先天性髋关节发育不良和脱位诊断中的临床价值

Clinical Value of High-frequency Ultrasound in Diagnosis of Congenital Hip Dysplasia and Dislocation

目的探讨高频超声应用于先天性髋关节发育不良和脱位临床诊断的价值。方法整群选用2014年1月—2014年12月,该院接受髋筛超声检查的6月龄内婴幼儿1 359例,采用Graf法进行高频超声髋关节检查,观察髋关节发育性异常(DDH)发生情况。结果1 359例(2716个髋关节)婴幼儿中,88例(6.48%)共130个(4.79%)髋关节为DDH;超声Graf诊断分型结果为1 271例(2 586个关节)Ⅰ型(正常),73例(113髋)Ⅱ型(髋关节发育欠成熟),13例(14髋)Ⅲ型(半脱位),2例(3髋)Ⅳ型(全脱位)。DDH阳性与临床诊断及X线检查结果完全一致,诊断符合率为100%。结论高频超声操作简便、无创伤且无放射性损伤、重复性好,对于DDH。的早期筛查、诊断及干预治疗具有重要意义。

Objective To investigate the value of high-frequency ultrasound in the clinical diagnosis of congenital hip dysplasia and dislocation. Methods 1359 cases of infants within 6 months of age who received high frequency ultrasound diagnosis in our hospital between January 2014 and December 2014 were collected, and all received high-frequency ultrasound examination of the hip by Graf method, and occurrence of dysplasia of the hip （DDH） was observed. Results In 1359 cases （2716 hip） infants, total 130 （4.79%） hip of 88 cases （6.48%） were DDH; graf ultrasound diagnostic genotyping result was 1271 cases （2586 hips） Ⅰ type （normal）,73 patients （113 hips） Ⅱ type （hip dysplasia less mature）,13 patients （14 hips） Ⅲ type （subluxation）,2 cases （three hips）Ⅳ type （full dislocation）. DDH positive was entirely consistent with the clinical diagnosis and X-ray findings, and the diagnosis rate was 100%. Conclusion High-frequency ultrasound is easy to operate, non-invasive and without radiation damage and with good repeatability. Therefore it is important for early screening, diagnosis and intervention of DDH.
