Analysis Of The Correlation Between The Prognosis Of Cervical Spondylotic Myelopathy And Its Imaging And Clinical Manifestations

Objective: To compare the imaging features of mild and severe cervical spondylotic myelopathy and to analyze the relationship between prognosis with the severity of the disease and the course of disease.Methods: A retrospective analysis from July 2015 to January 2017 in the Department of orthopedics of Shengjing Hospital affiliated to China Medical University from 82 cases of cervical spondylotic myelopathy,Department of orthopedics by Japan Association JOA standard for evaluation.The group was divided into mild group(9-17 points)and severe group(0-8 points),measured and compared between the two groups before operation,the degree of curvature of cervical vertebra hyperosteogeny,disc compression percentage imaging manifestations and parameters;one year follow-up,in all cases the severity group according to preoperative duration divided into short duration group(less than one year)and long duration group(one year and above),respectively,compare the two group's JOA points improvement.and according to the postoperative the recovery was divided into the recovery group(JOA improvement rate ? 66.6%)and poor recovery group(JOA improvement rate < 66.6%).Find the differences between two groups of preoperative imaging findings.Results:1,Mild and severe in two groups of patients with vertebral bone hyperplasia degree,the rate of spinal stenosis,posterior longitudinal ligament ossification of yellow ligament calcification,spinal cord MRIT2 high signal range,disc compression percentage difference was significant(P<0.05);the protrusion of the intervertebral disc segments,cervical curvature change have no significant difference(P>0.05)2,82 patients were treated with surgical treatment,and there were no severe complications such as massive bleeding or death.All patients were improved to different degrees of nerve function at 3 months after operation.In 6 months after the operation,3 cases had lower JOA score compared with 3 months after operation,and 1 cases recovered after the operation.12 months after the operation,there were 1 cases of JOA reduction compared with 6 months after the operation.The JOA scores were improved in all patients 12 months after surgery compared with preoperative.3,compared with the severe group,the improvement rate of JOA in the mild group was higher than that in the severe group at 3/6/12 months(P<0.05).4,and in the short course group compared with the long course group,the improvement rate of JOA was higher at 3/6/12 months after operation than that in the severe course group(P<0.05).5.3/6 months after surgery,recovery group and poor recovery group in the preoperative image study of poor performance compared with statistical significance of spinal cord MRIT2 high signal range difference(P<0.05)and other parameters were no significant difference(P>0.05);the difference was not statistically significant at 12 months after surgery to compare these two groups the imaging parameters(P>0.05).Conclusion: Severe cervical spondylotic myelopathy in most cervical spine imaging were more serious than mild;the operation mode of direct and indirect decompression and other treatment can achieve different effects,and mild cervical spondylotic myelopathy,preoperative short duration,spinal cord lesions in patients with less postoperative recovery more optimistic.Therefore,in the clinical treatment,for the patients with the symptoms of nerve compression,as long as it is necessary to determine the need for surgical treatment,regardless of the severity,they should be operated as soon as possible.
