| 目的：研究桡神经深支在旋后肌区正常的超声表现，确立其进入和行出旋后肌的标准切面，以及在标准切面上测量桡神经深支的前后径。
方法：用高频高频超声检查101例正常人桡神经深支进入，行出旋后肌浅深层的部位，并观察桡神经深支、测量其进入，行出时的神经外膜之间的前后径。
结果：超声切面上桡神经深支穿旋后肌行走，回声表现为横切面上呈椭圆形中等偏高回声；纵切面上呈多条线性的平行稍强同声。可确立其进入和行出旋后肌的标准切面，并测量桡神经深支进入旋后肌。行出旋后肌的处的前后径平均值分别为0.1085cm，0.1087cm，其进入和行出旋后肌的正常值参考范围分别为0.0773~0.1397cm，0.0786~0.1388cm。
结论：高频超声可用于扫查桡神经的走形、形态、回声等超声表现，确立其进入行出旋后肌的标准切面，在标准切面上测量其进入和行出旋后肌区的前后径，并判断该前后径是否在正常范围内，故该研究为临床诊断桡神经深支在旋后肌区有无卡压提供了一种灵活、便捷、无创、可量化的模型。 |

| Abstract: |
| Objectives: We aimed to observe the echo texture expression of the deep branch of radial nerve，search for the standard scanning section by using ultrasound, which in those ultrasound sections, including cross section and longitudinal section, the deep branch of the radial nerve get in and out of the supinator muscle. And in those most common compression areas, measure the inlet and outlet diameter of the deep branch of the radial nerve.
Methods: Firstly, through 101 volunteers’ ultrasound scanning, observe the echo texture expression of the deep branch of radial nerve, and meanwhile，find out the inlet and outlet of the deep branch of the radial nerve pass through of the supinator muscle, confirm standard scanning section, including cross section and longitudinal section. Secondly, in cross section and longitudinal section of ultrasound, measure the inlet and outlet of the radial nerve diameters at the deep branch of the radial nerve enter and out of the supinator muscle, and note down the inlet and outlet measurements.
Results: In ultrasound, the deep branch of radial nerve show as hypoechoic nerve, the mean anteroposterior nerve diameters of the deep branch of radial nerve where enter and out of the supinator muscle are 0.1085cm，0.1087cm, The inlet and outlet normal reference range of the deep branch of radial nerve anteroposterior nerve diameters are 0.0773~0.1397cm，0.0786~0.1388cm, those Measurements can be used for the normal anteroposterior nerve diameters of the deep branch of radial nerve in those ultrasound scanning section.
Conclusions: High-frequency ultrasound is useful for detect The deep branch of the radial nerve enter and out of the supinator muscle, it can not only confirmed standard scanning section, including cross section and longitudinal section, but also detected the mean anteroposterior nerve diameters of the deep branch of radial nerve where enter and out of the supinator muscle. And the measurements can be used for diagnosis the deep branch of the radial nerve syndrome compression by the arcade of Frohse of the supinator muscle. |
