In the past, the diagnosis of hourglass-like fascicular constriction(s) of the anterior interosseous nerve mostly depended on electrophysiological examination, by which the location could not be diagnosed. There are few studies on the evaluation of hourglass-like fascicular constriction(s) by ultrasonography.
To evaluate the role of ultrasonography in the diagnosis of hourglass-like fascicular constriction(s) of the anterior interosseous nerve.
A retrospective analysis of 12 patients with hourglass-like fascicular constriction(s) of the anterior interosseous nerve was carried out, and the characteristics of the high-frequency ultrasonographic images were summarized and compared with surgical exploration.
The 12 cases of hourglass-like fascicular constriction(s) of the anterior interosseous nerve were all located in the median nerve of the distal upper arm, including nine cases of single hourglass-like fascicular constriction and three cases of multiple hourglass-like fascicular constrictions. High-frequency ultrasonography can accurately locate the hourglass-like fascicular constriction(s) of the anterior interosseous nerve and the extent of neuropathy. The ultrasonographic images of hourglass-like fascicular constriction(s) of the anterior interosseous nerve showed single or multiple hourglass-like change(s) in the median nerve of the distal upper arm. The nerve fascicles on both sides of the affected nerve with hourglass-like change thickened.
High-frequency ultrasonography could be a reliable, convenient, and non-invasive diagnostic imaging method for hourglass-like fascicular constriction(s) of the anterior interosseous nerve.
过去，骨间前神经沙漏样束状狭窄的诊断主要依赖于电生理检查，但无法通过该检查诊断其位置。关于超声评估骨间前神经沙漏样束状狭窄的研究较少。
评估超声在骨间前神经沙漏样束状狭窄诊断中的作用。
对12例骨间前神经沙漏样束状狭窄患者进行回顾性分析，总结高频超声图像特征，并与手术探查结果进行比较。
12例骨间前神经沙漏样束状狭窄均位于上臂远端的正中神经内，其中单发沙漏样束状狭窄9例，多发沙漏样束状狭窄3例。高频超声能够准确显示骨间前神经沙漏样束状狭窄的位置及神经病变范围。骨间前神经沙漏样束状狭窄的超声图像表现为上臂远端正中神经呈单处或多处沙漏样改变，病变神经两侧的神经束增粗。
高频超声可作为诊断骨间前神经沙漏样束状狭窄的一种可靠、便捷且无创的影像学检查方法。
