摘　　要：目的分析桡神经深支在旋后肌区的声像图特征,并探讨其前后径的正常值范围。方法对101例健康志愿者桡神经深支进入、行出旋后肌浅深层的部位进行超声检查,观察桡神经深支声像图特征,测量其进入、行出时神经外膜之间的前后径。结果桡神经深支穿旋后肌行走,超声表现为横切面上椭圆形中等偏高回声,纵切面上多条线性的平行稍强回声。桡神经深支进入和行出旋后肌时神经外膜之间的前后径分别为(1.085±0.159)mm和(1.087±0.153)mm,桡神经深支进入和行出旋后肌时神经外膜之间的前后径超声测值正常值参考范围为0.773~1.397 mm和0.786~1.388 mm。结论桡神经深支穿旋后肌行走具有清晰的超声图像,且桡神经深支进入和行出旋后肌时神经外膜之间的前后径超声测值可为临床提供正常值的参考范围。Objective To analyze the ultrasonic characteristics of deep branch of radial nerve in the region of supinator muscle,and to investigate the normal diameter of deep branch of radial nerve.Methods Ultrasonography was perfomed on the deep branch of radial nerve in101volunteers,the ultrasonic characteristics of deep branch of radial nerve in cross section and longitudinal section were observed when it enters and exits the supinator muscle,the anteroposterior diameter of deep branch of radial nerve was measured.Results The deep branch of radial nerve traveled through the supinator muscle.In cross section,it showed isoechoic or slightly hyperechoic oval structure.In longitudinal section,it showed parallel hyperechoic linear structure.The anteroposterior diameter of deep branch of radial nerve when it enters and exits the supinator muscle were(1.085±0.159)mm and(1.087±0.153)mm.The normal reference range of anteroposterior diameter of deep branch of radial nerve were0.773~1.397mm and0.786~1.388mm.Conclusion The deep branch of radial nerve has a clear ultrasonic image when it enters and exits the supinator muscle,and measuremrnt of anteroposterior diameter of deep branch of radial nerve can provide normal reference value for clinic.
