后椎体

In some cases, the height of vertebra could be increased after the operation, however, it is not for the technology but for the posture of patients that the patients would pronate on the table and over-straight their bodies. In this situation, bone cement can be injected into the vertebras and enhance the int ensity, change the spine kyphosis, recover the spine physiological line, so it gets to the aim of treatment.

有时病椎术后高度增加，不是椎体成形术操作本身抬高椎体高度，而是在病人俯卧位时进行的体位引起过伸而复位，此时椎体内再加入骨水泥固化，使椎体固定在复位后的位置上，并且增加了耐压强度，同时改变了脊柱的后凸畸形，恢复了脊柱生理力线，这样就会达到治疗目的。

Methods There were 12 cases, 10 of them were corpse specimens, the other 2 were clinic cases. Firstly we dissociate the contralateral C7 root from the intervertebral foramen to its divisions, secondly we set up a tunnel between the cone and the anterior scalenus, thirdly we moved the C7 root to the gap between the thyroid and the opposite carotid theca through the mentioned tunnel, then we dissociate the injured brachial plexus extensively, lastly we anastomose the contralateral C7 and the injured inferior trunk.

尸解10例，临床应用2例，将健侧颈7神经近端游离至神经根孔，远端游离至前后股处，于前斜角肌后椎体前建立通道，将健侧颈7神经引导至患侧颈血管鞘和甲状腺间隙处，然后患侧行下干、内侧束、尺神经、及正中神经内侧头广泛游离，患侧屈肘屈肩关节后，将健侧颈7神经直接与患侧下干无张力下吻合。
