Cervical Myelopathy Comparison And Analysis Of Long-term Efficacy Of Surgical Treatment Of Cervical Posterior Two

Objective Compare the long-term efficacy and complications between expansive open—door laminoplasty and laminectomy which were used to treat cervical spondylotic myelopathy (CSM),and analyze the influencing factors.Methods The study mainly retrospectively analyzed the clinical data of91patients who had posterior cervical surgery in our hospital. They were divided into two groups. Group A (expansive open-door laminoplasty) comprised70patients,Group B (laminectomy) comprised21patients.Observe the change of preoperative and postoperative cervical curvature and intervertebral height,meanwhile compare the JOA score and postoperative complications in two surgery.Results There was no significant difference in the change of preoperative and postoperative cervical curvature and intervertebral height in group A (P>0.05), while there was significant difference in group B (P<0.05). The average JOA improvement rate were71.28%for group A and68.11%for group B in three months after the operation,and82.62%for group A and72.26%for group B in the long-term return survey. There was no significant difference between two surgery in JOA improvement rate in three months after the operation (P>0.05),but there was significant difference in the long-term return survey.Conclusion:The expansive open-door laminoplasty and laminectomy for CSM both can achieve satisfactory results,and the expansive open-door laminoplasty has less influence in the postoperative cervical curvature and intervertebral height than laminectomy.There was no significant difference between the two surgery in three months after the operation,while there was significant difference in the long-term return survey.
