健侧颈7神经移位经椎体径路的应用解剖学研究

目的 探讨健侧C7神经移位修复臂丛根性撕脱伤的最佳径路.方法 选用15具30侧成人尸体标本,显露双侧臂丛,将C7神经在干、股交界处切断并游离至椎间孔处,测量C7神经前、后股最大长度,分别测量C7神经根经椎体径路、椎前径路、颈前皮下径路至对侧臂丛上、下干的距离.结果 C7神经前、后股最大长度分别为(7.67±1.06)cm和(7.79±1.36)cm,C7神经经椎体径路、椎前径路、颈前皮下径路至对侧臂丛神经上千的距离分别为(6.97±0.56)cm、(10.04±0.94)cm、(16.56±1.24)cm,三组相比差异有统计学意义(P<0.01),至对侧臂丛神经下干的距离分别为(6.82±0.92)cm、(9.91±0.83)cm和(17.64±0.97)cm,三组相比,差异有统计学意义(P<0.01).结论 从解剖学角度,经椎体通路是健侧C7神经移位修复臂丛损伤的最佳径路.

The anatomical study of contralateral C7 transfer through the vertebral body route

Objective To find the optimal route of eontralateral C7 nerve transfer for brachial plexus avulsion injuries through autopsy. Methods The bilateral brachial plexus were exposed on 30 sides of 15 cadaverie specimens of adult. The C7 nerve root was sectioned at the junction site of trunk and division, and then dissected proximally to the foramina. The max length of anterior and posterior division of C7 was measured. The distance between the roof of C7 and the upper trunk and the lower trunk at the affected side through vertebral body route, prespinal route and a subcutaneous tunnel on the anterior surface of the neck was measured. Results The max length of anterior and posterior division of C7 was (7.67±1.06) cm and (7.79±1.36) cm respectively. The distance between the roof of C7 and the upper trunk at the affected side through vertebral body route, prespinal route and a subcutaneous tunnel on the anterior surface of the neck was (6.97±0.56) cm and (10.04±0.94) cm and (16.56±1.24) cm respectively, there were statistical significance among them (P < 0.01). The distance between the roof of C7 and the lower trunk at the affected side through vertebral body route and prespinal route and a subcutaneous tunnel on the anterior surface of the neck was (6.82±0.92) cm、(9.91±0. 83) cm and (17.64±0.97) cm, with a significant difference (P<0.01). Conclusion The best way of contralateral C7 nerve transfer for the treatment of brachial plexus injury was through the vertebral body route from the point of anatomy.
