目的解剖测量颈7神经根干股的可分离长度,为健侧颈7移位术提供解剖基础.方法对15例30侧成人颈胸段标本进行解剖,充分显露臂丛后用游标卡尺测量.测量内容包括颈7神经根-干的长度;颈7神经根-干-股(前、后股)的长度;颈7神经根部、干股结合部和前、后股的横径和纵径.用显微器械切开颈7神经股-束结合部的神经外膜,显微解剖直至其内的神经束融合不能分离为止,再次测量颈7神经的根-干前股及根-干-后股的长度.结果颈7神经根-干的长度:(45.87±10.43)mm;显微解剖分离前,颈7神经根-干-前股的长度:(61.14±13.44)mm;颈7神经根-干-后股的长度:(54.63±11.35)mm;显微解剖分离后,颈7神经根-干-前股的长度:(74.67±12.86)mm;颈7神经根-干-后股的的长度:(68.73±11.86)mm;前股延长的长度:(13.15±4.26)mm;后股延长的长度:(14.21±6.98)mm.经统计分析,左右两侧的神经长度差异无统计学意义,分离前、后的长度差异具有统计学意义.结论通过切开颈7神经股束结合部的神经外膜并作显微解剖可以延长神经切取长度,延长的长度分别为:前股为(13.15±4.26)mm;后股为(14.21±6.98)mm.

Objective To relatively prolong the length of C7 nerve through microanatomical study and carry out direct anastomosis between the end of avulsed nerve and contralateral C7. Methods Fifteen cadaveric specimens and 30 sides of the adult brachial plexus was dissected. The C7 nerve was confirmed and measured by using electric vernier caliper. Parameters as follow: the length of C7 nerve from root to trunk; the length of C7 nerve from root to division(anterior and posterior division); transverse and longitudinal diameter of C7 nerve in root site, combination site between trunk and division, end site of anterior and posterior division. After dissected the nerve adventitia of binding site between division and cord and cut the distal end of anterior and posterior division, the length of C7 nerve from root to division (anterior and posterior division)was measured again. Results The measured result of the length C7 nerve: the length of C7 from root to trunk: (45.87 ± 10.43)mm; Before micro-dissected, the length of C7 from root to anterior division: (61.14 ±13.44)mm; the length of C7 from root to posterior division: (54.63 ± 11.35)mm after micro-dissected, the length of C7 from root to anterior division: (74.67±12.86)mm; the length of C7 from root to posterior division:(68.73± 11.86)mm; the prolonged length of anterior division: (13.15± 4.26)mm; the prolonged length of posterior division: (14.21 ± 6.98)mm. Conclusion Through dessecting the adventitia of binding site of division (anterior and posterior division) and cord of C7 nerve. The length of C7 nerve can be relatively prolonged.
