摘　　要：目的探讨成人桡神经的超声表现,对正常桡神经及其属支面积及前后径定量测量。方法对100例健康成年人的桡神经进行高频超声检查,从形态学进行观察描述,并选取标志点测量及统计学分析得到桡神经正常测量值,对于可能影响测量值的因素进行统计学分析。结果 (1)超声可清晰显示桡神经。(2)正常值测量:肱骨桡神经沟下缘桡神经的前后径(1.60±0.31)mm,横截面积(3.41±0.51)mm^2;桡神经深浅支分支处深支前后径(1.04±0.18)mm,横截面积(1.06±0.20)mm^2;浅支前后径(0.94±0.16)mm,横截面积(1.00±0.21)mm^2。(3)影响因素:左右侧、男女间所测指标差异均无统计学意义。身高、体质量、BMI与所测部位桡神经横截面积、前后径相关性无统计学意义。结论桡神经主干及深浅支的形态学描述及定量测量可为临床工作提供重要信息。Objective To study the ultrasonographic appearance of normal adult radial nerves.To measure the cross-sectional area and the diameter of radial nerve by high-resolution ultrasonography.Methods The radial nerves of 100 healthy adults were examined by high-resolution ultrasonography.The morphological description and predetermined sites measurements of normal radial nerve were obtained.Factors that could affect the measurement values were statistically analyzed.Results（1）Ultrasonography can display radial nerve clearly.（2）At the level of radial sulcus,the diameter of radial nerve was（1.60±0.31）mm and cross-sectional area was（3.41±0.51）mm^2.At the level of lateral humeral condyle the diameter of the deep branch was（1.04±0.18）mm and cross-sectional area was（1.06±0.20）mm^2.The superficial branch diameter was（0.94±0.16）mm and cross-sectional area was（1.00±0.21）mm^2.（3）The measurements between bilateral,gender showed no statistical significance.The diameter and cross-sectional had no correlation with height,weight and BMI.Conclusions Morphological description and quantitative measurement of the radial nerve stem and branches can provide important information for clinical work.
