Abstract

Objective: To evaluate the results of anterior cervical discectomy and fusion surgery using self-locking stand-alone for the treatment of cervical herniation. Subject and method: Clinical description, prospective study. The study included 28 patients (19 men, 9 women), average age 52 ± 12.8 years old, who underwent anterior cervical discectomy and fusion using self-locking stand-alone cages at the Department of Neurosurgery, 108 Military Central Hospital from June 2021 to June 2022. Result: Most of them underwent single level (82.1%), there was no patients underwent three - levels or more. The main position was C4C5 (41.86%). There were 8 patients who had previously surgery to anterior cervical discectomy and fusion using plate. The average surgical time was 65.25 ± 12.36 minutes. The average blood loss was 54.58 ± 9.18ml. At 3 months after surgery, there was a significant improvement in neck VAS (5.23 ± 2.62 preoperative vs 1.09 ± 0.73 postoperative); hand VAS (4.65 ± 1.08 preoperative vs 1.03 ± 0.59 postoperative); NDI (38.29 ± 18.39 preoperative vs 17.33 ± 6.88 postoperative). The clinical manifestations were significantly improved after surgery, the preoperative mJOA score of 11.36 ± 3.58 increased to 14.62 ± 2.12 at the time of discharge, and reached an average of 16.08 ± 2.10 at 3 months postoperative (p<0.05). There were no complications of dysphagia after surgery. The rate of bone healing at 12 months after surgery reached 96%, there were no complications of displacement and subsidence of the graft. Conclusion: Cervical disc surgery, anterior bone grafting with self-locking screw grafts is an effective and safe method, good improvement in clinical symptoms, high healing rate. The rate of dysphagia complications is low and there is no graft displacement.
