A radiosurgery treatment planning was performed on the selected nerve segment, its changes of pathology and ultrastructure were observed. Results: Base on the dissection, the rabbits' sciatic nerve was composed of the seventh lumbar nerve and first and second sacral nerves. The sciatic trunk descended in front of the sacroiliac joint and escaped between the sacral bone and ilium, then left the pelvis from the greater sciatic notch.

结果：通过解剖可见坐骨神经主干由第7腰神经和第1、2荐神经组成，坐骨神经主干从荐髂关节下、荐骨和髂骨之间穿出后，跨过坐骨大切迹的一段坐骨神经主干位置恒定，且有荐骨和髂骨做定位标志，可作为CT定位的照射靶点，单次大剂量照射后镜下可见神经纤维变性坏死。

The rabbits were immobilized according to the standard of X_knife before CT scanning. The interrelation of the silica gel tube and bony structures was analyzed, a nerve segment was selected, which could be localized according to the related bony structures as irradiation target. A radiosurgery treatment planning was performed on the selected nerve segment, its changes of pathology and ultrastructure were observed. Results: Base on the dissection, the rabbits' sciatic nerve was composed of the seventh lumbar nerve and first and second sacral nerves.
