摘要
目的探讨超声检查对桡骨小头半脱位(RHS)的诊断价值。方法回顾性分析34例RHS患儿的临床及超声检查资料。所有患儿均接受常规双侧肘关节多切面、对比超声检查,且X线检查结果均为阴性。结果 RHS的超声表现包括:肱桡间距增宽29例(29/34,85.29%),关节间隙增宽、回声增强25例(25/34,73.53%),旋后肌上移并呈"钩"型表现32例(32/34,94.12%),环状韧带嵌顿33例(33/34,97.06%)。结论 RHS的声像图表现具有一定特征,通过超声连续扫查双侧肘关节,并进行对比,有助于快速、准确地对X线检查阴性的RHS做出诊断。
Objective To investigate the diagnostic value of ultrasonography in radial head subluxation （RHS）. Methods The clinical data and ultrasonographic findings of 34 children with RHS were retrospectively analyzed. All patients were routinely treated by bilateral compared and multi-sectional elbow joints ultrasonography. And the X-ray results were negative. Results Ultrasonographic manifestations of RHS included increased radiocapitellar distance in 29 cases （29/34, 85.29%）; widened joint space and enhanced echo in 25 cases （25/34, 73.53%）; ＂hook sign＂, supinator muscle above the radial head in 32 cases （32/34, 94.12%）; annular ligament entrapment in 33 cases （33/34, 97.06%）. Conclusion Ultrasonographic manifestations of RHS have certain characteristics. Comparation of bilateral elbow joints and the application of continuous scanning ultrasound are helpful to make a quick and accurate diagnosis of X-ray negative RHS.
