Embodiment Construction
[0032] Such as Figure 2-4 As shown, the operation process of X-shaped excision, decompression, vertebral body reconstruction and intervertebral fusion and fixation of the anterior cervical vertebral body involved in the present invention is as follows: first, a fan-shaped cross section is designed in the vertebral body, such as figure 2 shown. The ex vivo vertebral body obtained after resection is subsequently used as the regrafted bone block 21, and the radius of the fan-shaped contour of the regrafted bone block 21 accounts for about 60% of the anteroposterior diameter of the entire vertebral body. Secondly, use a rongeur and a drill to resect the back of the vertebral body. The incision is X-shaped, that is, the incision is in the shape of a small mouth and a large bottom, as in image 3 shown. The X-shaped incision can ensure the visual field during the operation, and can complete the resection of the osteophyte and ossification of the posterior longitudinal ligament t...
