摘　　要：目的通过对臂丛神经的解剖学大体观察和测量,为临床骨科医生对臂丛神经损伤的手术治疗提供解剖学数据,并为解剖学积累新资料。方法对40具国人尸体标本(26具,女14具),80侧臂丛神经,进行研究。首先对标本进行大体观察,描述其解剖学形态,进行分型、分类及内、外、后束合成部位与第一肋外缘的关系;用相关的测量工具(电子游标卡尺)测量上、中、下三干前、后股的比例及根干束的长度并进行统计学分析。结果根干束的长度,C5根:男(33.85±7.07)mm,女(30.30±5.25)mm,C7根和中干:男(52.46±10.55)mm,女(44.15±6.68)mm;C8根:男(25.55±5.88)mm,女(19.91±5.09)mm;T1根:男(23.81±5.58)mm,女(19.16±4.02)mm;上干:男(24.69±9.91)mm,女(18.86±4.93)mm,下干:男(33.13±9.21)mm,女(25.44±9.41)mm;后束:男(31.21±13.93)mm,女(37.36±9.93)mm。结论除C4根、C6根、T2根、内侧束和后束外,性别不同,其臂丛神经解剖学长度差异均有统计学意义。提示在临床麻醉及手术治疗臂丛神经损伤时一定要注意。Objective To provide accurate anatomy figures of operational treatment of brachial plexus nerve injury for clinical orthopedist by observing and measuring brachial plexus nerve and to accumulate new anatomical datas and compare to observation of predecessors. Methods 80 brachial plexus nerve of 40 national cadaver specimens （man 26 and woman 14） were studied. Firstly, anatomical appearance was described and classified by observing specimens and the relation between the combining site of medial lateral and posterior cord and exterior of the first rib; Secondly, using measurement tools to measure the ratio of anterior and posterior division of superior, middle and inferior trunks and the length of roots, trunks and cords and making statistical analysis. Results The length of root, trunk and cord, C5 root： man 33.85±7.07 ram, woman（30.30±5） ram;C7 root and middle trunk： man 52.46±0.55 mm, woman 44.15±6.68 mm; C8 root： man（25.55±5.88）mm, woman（19.91 ±5.09）mm; T1 root：man （23.81±5.58）mm, woman（19.16±4.02）mm; superior trunk： man（24.69＋ 9.91）ram, woman （18.86±4.93）mm; inferior trunk：man （33.13±9.21）mm, woman（25.44±9.41）mm; posterior cord： man （31.21±13.93）mm, woman （37.36±9.93）mm. Conchlsion The sexual diversity of the length of roots, trunks and cords is obvious except C4, C6, T2 and medial and posterior cords. Thus, the great attention should be paled to clinical anesthesia and operational treatment of brachial plexus nerve injury.
