研究设计.尸体可行性研究共包括6具福尔马林固定尸体。Objective.目的：探讨颈后路硬膜外健侧C7前根移位术的解剖学可行性。背景数据总结。上肢痉挛性偏瘫是脑卒中后常见的后遗症。在我们以前的研究中，作者建立了一种将健侧C7背根和前根转移到患侧相应的C7背根和前根的方法。方法.在本研究中，六福尔马林固定的尸体解剖，以确认解剖的可行性。在尸体上进行了实验吻合。测量硬膜外神经根的相关长度。观察硬膜外CC7神经根与椎动脉之间的组织结构。对60例成人颈椎进行MRI扫描，测量供、受神经之间的距离。结果实验吻合表明，供、受神经之间的距离约为1cm，短段腓肠神经需桥接。硬膜外CC7前根的长度为22.00 ± 0.98 mm，腹侧距离（vd）为23.98 ± 1.72 mm，背侧距离（dd）为30.85 ± 2.22 mm（P
Study Design. A total of 6 formalin-fixed cadavers were included in the cadaver feasibility study. Objective. The aim was to ascertain the anatomical feasibility of extradural contralateral C7 ventral root transfer technique by cervical posterior. Summary of Background Data. Upper limb spastic hemiplegia is a common sequela after stroke. In our previous study, the authors established a method by transferring contralateral C7 dorsal and ventral roots to the corresponding C7 dorsal and ventral roots on the affected side in the cervical posterior. Methods. In the present study, six formalin-fixed cadavers were dissected to confirm the anatomical feasibility. Experimental anastomosis in cadavers was conducted. The pertinent lengths of the extradural nerve roots were measured. The tissue structures surrounding regions between the extradural CC7 nerve roots and the vertebral artery were observed. The cervical magnetic resonance imaging scans of 60 adults were used to measure the distance between the donor and recipient nerves. Results. Experimental anastomosis showed that the distance between the donor and recipient nerves was approximately 1 cm; the short segment of the sural nerve needed bridging. The distance between both exit sites of the exit of the extradural dura mater was 33.57 +/- 1.55 mm. The length of the extradural CC7 ventral root was 22.00 +/- 0.98 mm. The ventral distance (vd) and the dorsal distance (dd) in males were 23.98 +/- 1.72 mm and 30.85 +/- 2.22 mm (P
