目的探讨高频超声检查在快速诊断儿童难复性桡骨小头半脱位中的应用价值.方法 23例难复性单侧桡骨小头半脱位儿童,年龄1～5岁,行双侧肘关节多切面高频超声及X线检查,并与健侧对比,观察患侧桡骨小头相对于肱骨小头的位置变化.结果 X线均未检出桡骨小头半脱位,高频超声检出桡骨小头半脱位23例,伴有关节腔积液者10例,超声图像上表现为肘关节前区桡侧纵切面及外侧冠状面显示低回声的桡骨小头相对于高回声的肱骨小头有明显移位.结论高频超声在儿童难复性桡骨小头半脱位诊断方面的敏感性明显高于X线片;高频超声通过连续扫查可观察肘关节周围解剖结构的连续性及毗邻关系,尤其双侧对比前区桡侧纵切面、外侧区冠状面可快速、准确地诊断儿童难复性桡骨小头半脱位.

Objective To explore the application of high frequency ultrasonography in the rapid diagnosis of irreducible radial head subluxation in children.Methods Twenty-three patients aged 1 to 5 with unilateral radial head subluxation in children were observed by high-frequency ultrasonography and radiography,and then compared the symptomatic to the contralateral side.Results No case of radial head subluxation was found by radiography.23 cases of radial head subluxation were found by high frequency ultrasonography,10 cases with articular cavity effusion.On the diagnosis of radial head subluxation in children,the sensitivity of high frequency ultrasonography was obviously higher than that of radiography.Conclusions The sensitivity of high frequency ultrasonography in the rapid diagnosis of the radial head subluxation in children is obviously higher than that of X ray film.High frequency ultrasonography through continuous scan can determine the continuity of anatomical structure and the relationship between some views to show the location of the specific structure relations.Specifically,it can be quickly and clearly diagnosed on anterior long-axis view and the lateral coronal view of radiohumeral joint.
