Study On The Correlation Between The Changes Of Spinal Cord Signal On MRI And The Efficacy Of CDR In CSM Patients

Objective:To compare and analyze the postoperative therapeutic effects of different grades of MRI spinal cord high-signal grading on patients with cervical spondylotic myelopathy after arti ficial cervical disc replacement,thus to provide a basis for clinical surgical selection and to expand clinical thinkingMethods:The pathological tracing,syndrome differentiation and prescription of cervical spondylotic myelopathy were explored theoretically by searching the Chinese literature database to deeply understand the advantages and characteristics of traditional Chinese medicine in the treatment of cervical spondylotic myelopathy.In clinical studies,30 patients who underwent artificial cervical disc replacement for cervical spondylotic myelopathy in the Department of Orthopaedics,Jiangsu Province Hospital of Chinese Medicine from July 2015 to June 2017 were followed up.According to the MRI spinal cord high-signal grading,patients were divided into three groups of Grade 0,Grade I and Grade II.The age,duration of disease,preoperative and postoperative JOA scores,neck dysfunction index(NDI)score,rate of the improved JOA score,the time of resuming normal working and life after operation were compared and analyzed.The analysis was performed using SPSS22.0 software.The overall comparison between different groups was analyzed through variance analysis and the LSD method was used for pairwise comparison between groups.The postoperative efficacy of artificial cervical disc replacement in different spinal cord high-signal grades was evaluated.Results:There was no statistical difference in age,duration and gender between the three groups.After 1-3 years of follow-up,there was no statistical difference in preoperative JOA score,postoperative JOA score,rate of the improved JOA score,NDI score and the time of resuming normal working and life after operation.Conclusion:MRI spinal cord high-signal grading cannot be used to determine the severity of cervical spondylotic myelopathy and has no significant impact on the postoperative effect in patients with cervical spondylotic myelopathy after artificial cervical disc replacement surgery.
