Clinical Observation Of Anterior Decompression Of The Posterior Longitudinal Ligament Of The Longitudinal Ligament Based On The Theory Of "The Weight Of The Muscles And Bones"

Objective:Clinical observation on the treatment of cervical spondylotic myelopathy with posterior longitudinal ligament decompression in the superficial layer of the longitudinal ligament,based on the theory of "joint weight of muscles and bones".Methods:From September 2015 to March 2017 patients were collected in the spinal Department of orthopedics of the Affiliated Hospital of Shandong University of Traditional Chinese Medicine in 60 cases of cervical spondylotic myelopathy with anterior cervical corpectomy decompression and interbody fusion with titanium mesh and bone graft fixation plate,the treatment group in anterior cervical corpectomy decompression and interbody fusion with titanium mesh bone plate internal fixation based on the theory of "bones" and retain the posterior longitudinal ligament superficial in 30 patients in the control group,anterior cervical corpectomy decompression and interbody fusion with titanium mesh and bone graft in 30 cases of longitudinal ligament fixation after resection of the patient.The sex and age of the patients,the hospitalization period(hospitalization time,the amount of bleeding,the time of operation);according to Visual Analogue Scale VAS(score of pain visual analogue scale),pain relief was compared between the treatment group and the control group;according to the JOA(Japanese Orthopaedic Association Scores JOA)score of the Japanese Department of orthopedics society 6 months before operation,12 months after operation,the symptom improvement and neurological recovery were compared between the treatment group and the control group.6 months and 12 months after surgical treatment,the patients in the treatment group and the control group were judged by the fusion of cervical CT(cervical CT plain scan plus sagittal reconstruction).Results:1.sex and age: the treatment group compared with the control group P>0.05,no statistical significance,no significant difference.2.in the time of hospitalization: the treatment group compared with the control group P>0.05,no statistical significance,no significant difference.3.in terms of operative time and operative blood loss:the treatment group was less than the control group.The difference between the two groups was statistically significant(P<0.05),there was significant difference between the two groups.4.in the VAS score:the treatment group and the control group were significantly improved after the operation,but there was no significant difference in the degree of improvement between the two.5.in the cervical spine JOA score: the treatment group and the control group were significantly improved in June and December compared with those before operation,and the improvement rate in the treatment group was better than that in the control group in June and December.6.The comparison of the fusion between the two groups: the treatment group was better than the control group in June and December after the operation.Conclusion:Based on the theory of muscle and bone,the anterior cervical decompression for cervical spondylotic myelopathy has a good clinical effect.It is worthy of wide clinical application.
