    Abstract:
    OBJECTIVE: To explore the safety, effectiveness and consistency of "Zoning Method" foraminotomy in posterior cervical endoscopic surgery. METHODS: From March 2016 to October 2018, 21 patients with cervical spondylotic radiculopathy were enrolled. Endoscopic foraminotomy and nucleus pulposus enucleation were performed in the patients. There were 13 males and 8 females, aged from 35 to 56 years old with an average of (47.3±5.1) years. The surgical segment of 6 cases were C4,5, 10 cases were C5,6 and 5 cases were C6,7. The "Zoning Method" was proposed and used to complete the foraminotomy under endoscope, and then to perform nucleus pulposus removal and nerve root decompression. The operation length, intraoperative bleeding volume and complications were recorded, and NDI, VAS were evaluated before operation, 1 day after the operation and 1 week after the operation. RESULTS: All the operations were successful. The operation length was(46.10±26.39) min, intraoperative bleeding volume was (50.10±18.25) ml, and there were no complications such as nerve injury, dural tear or vertebral artery injury. All 21 patients were followed up for 3 to 9 months, with a median of 6 months. Postoperative VAS and NDI were obvious improved (P<0.05);there was significant difference in VAS between postoperative 1 d and 1 week(P<0.05);and there was no significant difference in NDI between postoperative 1 d and 1 week (P>0.05). CONCLUSION: Endoscopic foraminotomy with "Zoning Method" is safe clinically significant, and consistent.
