The Relationship Between The Morphological Changes Of Spinal Cord And Clinical Symptoms And Prognosis Of Cervical Spondylotic Myelopathy On Axial MRI

Objective To investigate the relationship between spinal cord morphological changes and clinical symptoms and prognosis by measuring the relationship between the spinal cord area ratio and the JOA score and improvement rate before and after treatment.Methods A retrospective collection of 120 patients with cervical spondylotic Myelopathy at the General Hospital of Ningxia Medical University clinic and hospitalization was divided into 4 groups according to the cervical spine MRI T2W1 axial spinal cord morphological changes,including 30 cases of type ?,19 cases of male,female 11 For example,age 29-56 years old,mean age 42.73 years old;type ? male 16 cases,female 14 cases,age 27-68 years old,mean age 48.77 years;type ?I 30 cases,male 17 cases,female 13 cases,age 28-71 years old,with an average age of 52.34 years;30 cases of type ?V,25 males and 5 females,aged 30-80 years,mean age 58.03 years old.30 normal adults who underwent cervical vertebrae MRI signs from the cervical spine in the General Hospital of Ningxia Medical University from January 2015 to December 2017 were included in the control group.There were 15 males and 15 females,aged 18-69 years,with an average age of 37.82.year old.Cervical MRI was performed in all normal adults and patients.The spinal canal area and spinal cord area of C4-5 were measured on the T2W1 image of the cervical vertebra.The area was evaluated by using the JOA score to evaluate the cervical spinal cord function.The JOA scores of patients with cervical spondylotic myelopathy at 3 months after treatment,1 year after treatment,and the last follow-up were counted,respectively,to calculate the improvement rate.Results1.The spinal cord area of type ?,type ?,type ?I and type ?V in CSM group increased with the increase of type,and the area occupied by the spinal cord increased.2.The JOA scores of type ?,type ?,type ?I and type ?V in CSM group were statistically different(p<0.05);the JOA scores of type ? and ? and type ?V we restatistically different(p<0.05);type ?I and The JOA score of type ?V was stati stically different(p < 0.05).3.The JOA scores of type ?,? and ? in CSM group were statistically differ ent(p<0.05).The JOA scores of type ?,? and ? in CSM group were statistic ally different(p<0.05).The JOA scores of type ?,? and ? in the CSM group at the last follow-up after treatment were statistically significant(p<0.05).Conclusion Morphological changes of the spinal cord are related to the spinal canal area;Morphological changes of the spinal cord are closely related to the clinical symptoms of cervical spondylotic myelopathy,which can be used as one of the indicators for judging clinical symptoms;Morphological changes of the s pinal cord and The postoperative improvement rate is closely related and can be used as one of the indicators to judge the prognosis of surgery.
