INTRODUCTION
In this study we provide detailed quantification of upper extremity nerve and fascicular anatomy. The purpose is to provide values and trends in neural features useful for clinical applications and neural interface device design.
METHODS
Nerve cross-sections were taken from 4 ulnar, 4 median, and 3 radial nerves from 5 arms of 3 human cadavers. Quantified nerve features included cross-sectional area, minor diameter, and major diameter. Fascicular features analyzed included count, perimeter, area, and position.
RESULTS
Mean fascicular diameters were 0.57 ± 0.39, 0.6 ± 0.3, 0.5 ± 0.26 mm in the upper arm and 0.38 ± 0.18, 0.47 ± 0.18, 0.4 ± 0.27 mm in the forearm of ulnar, median, and radial nerves, respectively. Mean fascicular diameters were inversely proportional to fascicle count.
CONCLUSION
Detailed quantitative anatomy of upper extremity nerves is a resource for design of neural electrodes, guidance in extraneural procedures, and improved neurosurgical planning. Muscle Nerve 56: 463-471, 2017.
引言
在本研究中，我们对上肢神经和束状解剖结构进行了详细的量化分析。目的是提供对临床应用和神经接口设备设计有用的神经特征值及趋势。
方法
从3具人类尸体的5只手臂上获取了4条尺神经、4条正中神经和3条桡神经的横截面。量化的神经特征包括横截面积、短径和长径。分析的束状特征包括数量、周长、面积和位置。
结果
尺神经、正中神经和桡神经在上臂的平均束状直径分别为0.57±0.39、0.6±0.3、0.5±0.26毫米，在前臂的平均束状直径分别为0.38±0.18、0.47±0.18、0.4±0.27毫米。平均束状直径与束数成反比。
结论
上肢神经的详细定量解剖是神经电极设计、神经外手术指导及改进神经外科手术规划的资源。《肌肉与神经》56: 463 - 471, 2017年。
