摘要：

近年来许多研究以高频超声观察正中神经和尺神经，较少见观察桡神经的报道，而桡神经比尺神经和正中神经更容易受卡压伤，但桡神经的正常参考值一直没有确定标准。因此实验应用高频超声测量200名18-75岁不同性别的健康志愿者桡神经横截面积。结果发现桡神经在肱骨外髁上4cm、肱骨中点的横截面积分别为5.14±1.24和5.08±1.23mm2，且年龄和优势侧对结果无影响，但男性的挠神经在肱骨外髁上4cm、肱骨中点的横截面积为5.31±1.25和5.19±1.23 mm2，均大于女性对应位置的挠神经横截面积（4.93±1.21和4.93±1.23 mm2），桡神经横截面积与身高和体质量呈正相关（r=0.38，0.36，P<0.05）。这为将来高频超声在周围神经病变的诊断、治疗及预后评估等领域提供了临床基础数据。

Abstract:

High-resolution ultrasound has been used recently to characterize median and ulnar nerves, but is seldom used to characterize radial nerves. The radial nerve is more frequently involved in entrapment syndromes than the ulnar and median nerves. However, the reference standard for normal radial nerves has not been established. Thus, this study measured the cross-sectional areas of radial nerves of 200 healthy male or female volunteers, aged 18 to 75, using high-resolution ultrasound. The results showed that mean cross-sectional areas of radial nerves at 4 cm upon the lateral epicondyle of the humerus and mid-humerus (midpoint between the elbow crease and axilla) were 5.14 ± 1.24 and 5.08 ± 1.23 mm2, respectively. The age and the dominant side did not affect the results, but the above-mentioned cross-sectional areas were larger in males (5.31 ± 1.25 and 5.19 ± 1.23 mm2) than in females (4.93 ± 1.21 and 4.93 ± 1.23 mm2, respectively). In addition, the cross-sectional areas of radial nerves were positively correlated with height and weight (r = 0.38, 0.36, respectively, both P < 0.05). These data provide basic clinical data for the use of high-resolution ultrasound for the future diagnosis, treatment, and prognostic evaluation of peripheral neuropathies.
