| Objective: To explore the application value of MC+ cervical fusion cage in the anterior treatment of degenerative cervical spondylosis.Methods: Review all the patients with one-level degenerative cervical spondylosis who diagnosed as "cervical spondylosis","cervical spondylotic myelopathy","cervical spondylotic radiculopathy" and "cervical disc herniation" in The First Affiliated Hospital of Guangxi Medical University from January 2015 to December 2016,and in The Second Affiliated Hospital of Guangxi Medical University from January 2017 to December 2018 in total 44 case.All of them were followed up for more than 6 months with relatively complete clinical data.15 patients in Zero profile group were treated by anterior cervical discectomy + MC+ cervical fusion cage combined with bone grafting.The other 29 patients in Titanium cage and plate group were treated by anterior cervical discectomy + titanium cage fusion and titanium plate internal fixation.The operation time,intraoperative blood loss,postoperative drainage,fusion angle(FA),cervical curvature(CC),anterior segmental height(ASH),posterior segmental height(PSH),JOA score,VAS score,bone graft fusion rate and complication rate during follow-up were statistically analyzed.Results: The symptoms and signs of all patients were improved at the last follow-up,and there was no significant difference in follow-up time between the two groups.The operation time,blood loss and postoperative drainage in Zero profile group were less than those in Titanium cage and plate group.Titanium cage displacement occurred 1case in the Titanium cage and plate group,swallowing discomfort 2cases,and swallowing discomfort 1 case in the Zero profile group.The symptoms of swallowing discomfort in both groups disappeared within2 weeks after operation.At the last follow-up,there were 1 cases of adjacent segment degeneration in the Zero profile group and 3 cases in the Titanium cage and plate group.At the last follow-up,the fusion rate of bone graft in both groups was 100%,and there was no screw pull-out,lock piece loosening or displacement.At the last follow-up,the average cervical curvature(CC)and average fusion angle(FA)in two groups were significantly improved as compared with those before operation,and the difference was statistically significant,but there were no statistical difference between the two groups.Although the anterior segmental height(ASH)and posterior segmental height(PSH)of two groups decreased in varying degrees during the last follow-up,the anterior segmental height(ASH)of the two groups was significantly improved compared with that before operation,the difference was statistically significant.At the last follow-up,the posterior segmental height(PSH)of the test group maintained well,which was significantly better than that before operation,while the posterior segmental height of the control group lost significantly,slightly lower than that before operation,but there was no statistical difference.The postoperative VAS score and JOA score of the two groups were significantly improved as compared with those before operation at the last follow-up.Conclusion: Using MC+ cervical fusion cage to treat degenerative cervical spondylosis with single space spinal cord or nerve root compression being free from using plate,is relatively simple and Less trauma,which reduces complications related to screws and plate internal fixation.The need for bone grafting can be met by taking the hyperplastic osteophyte and properly taking the bone of the anterior and posterior edge of the vertebral body,and the fusion effect is good.there was no need to take iliac bone,Avoiding complications in the bone extraction area.It Avoids the shortage of use allogeneic bone or artificial bone.Good intervertebral height and cervical physiological curvature can be maintained after operation.and the overall medium-term effect is satisfactory.However,the long-term effect still needs a larger sample size and a longer follow-up study... |
