| ［摘要］目的 应用超声对正常腕部神经干进行扫查，拟对超声评估周围神经的临床应用价值进行探讨．方法 应用高频超声对100例正常人腕部正中神经、尺神经、桡神经进行扫查，观察其走行、形态及内部回声表现，并进行纵横径及横断面积测量．结果（1）超声能够清晰显示神经及周围组织结构的解剖断面；（2）超声能够对神经进行径线及横截面积的测量．正中神经前后径及桡神经前后径同性左右侧比较差异无统计学意义（P＞0.05），尺神经前后径女性左右侧比较差异无统计学意义（P＞0.05），尺神经前后径男性左右侧比较差异有统计学意义（P＜0.05），正中神经、桡神经、尺神经前后径异性同侧比较差异有统计学意义（P＜0.05）；正中神经CSA、尺神经CSA、桡神经CSA同性双侧对比差异无统计学差异（P＞0.05），正中神经CSA、尺神经CSA、桡神经CSA异性同侧比较差异有统计学差异（P＜0.05）；（3）正中神经横截面积（CSA）与体重相关性差异有统计学意义（P＜0.05），与年龄及身高相关性差异无统计学意义（P＞0.05）．结论 高分辨率超声能够诊断和评估上肢神经病变． |

| Abstract: |
| ［Abstract］Objective To evaluate the clinical value of ultrasound in evaluating the wrist nerve stem．Methods The examination of the high-resolution ultrasound about normal median nerve，ulnar nerve，radial nerve in the wrist on 100 normal volunteers，the courser，shape and sonographic appearance of the nerve stem were observed，and the vertical and horizontal diameter and the area of cross-section were measured．Results（1）Ultrasound clearly showed the nerve stem arranged and organization structures around it.（2）Ultrasound entirely measured the vertical and horizontal sections of normal median nerve，ulnar nerve，radial nerve in the wrist，besides it measured various diameters and the cross-section area. By comparing the vertical diameter of MN and RN between left hand and right hand of the same sexuality，the difference had no statistical significance（P＞0.05）.By comparing the various diameters of UN between left hand and right hand of females，the difference had no statistical significance（P＞0.05）．By comparing the vertical diameter between left hand and right hand of male ，the difference had statistical significance（P＜0.05）.To compare the vertical diameter of MN， RN and UN between male and females on the same side，the difference had statistical significance （P＜0.05）.To compare the CSA of MN， RN and UN between left hand and right hand of the same sexiuality， the diffevence had no statistical significance（P＞0.05）；By comparing the CSA of MN，RN and UN between male and females on the same side，the diffevence had statistical significance（P＜0.05）.Median nerve cross-sectional area （CSA） and weight correlation was statistically significant （P < 0.05） in a straight line， no statistically significant correlation was found between age and height （P > 0.05）. （3）High resolution ultrasound clearly showed the neural surrounding adjacent to the organizational structure，and in line with gross anatomy section. Conclusion Ultraound has a clinical evalution value for examing the wrist nerve |
