Objective To investigate the resu Hs of the Centerpiece cervical posterior internal fixation sys-tem in the application of the single door cervical vertebral tube expanding plasty. Methods Throush opening the door by single vertebral canal expanded forming Centerpiece cervical posterior fixation treatment of multiple segmental was done in 22 patients with degenerative disease of cervical vertebrae, According to the evaluation method for the 17 points score (JOA) postoperative neurologic recovery, X-ray, CT and MRI were performed to observe the spinal cord decompression bone door shaft side. Results The sagittal diameter of the vertebral ca-nal increased, with a significant increase in the vertebral canal cross sectional area,and a good spinal cord; with all osseous fusion of hinge side, without "shut down" phenomenon; nor cervical segmental instability and cervi-cal curvature changes The preoperative JOA scores were 5~15 (10.18+2.67) points; and the post-operative scores 7~17 points (13.18+2.75). The average improving rate was 45.86%. Conclusion Centerpiece of cervi-cal posterior internal fixation application in the single door cervical vertebra tube expanding keratoplastyis safe and effective;at the same time, the cervical vertebra can obtain immediate stability.
