Comparison Of The Efficacy Of Removal And Retention Of The Posterior Longitudinal Ligament In The Subtotal Decompression For Treatment Of Spinal Cord-type Cervical Spondylosis

Objective: Explore the posterior longitudinal ligament resection and retainedvertebral subtotal decompression treatment of cervical spondylotic myelopathy effects.Methods: Retrospective analysis of the past six years (October2005to October2011)Affiliated Hospital of Shandong University of Traditional Chinese Medicine SpinalOrthopedic，Due to decompression for the treatment of cervical spondylotic myelopathyOK vertebral total resection in-patients, Total met the inclusion criteria and complete dataof60cases Group of30patients (of which A group of cervical anterior vertebral excisionof the posterior longitudinal ligament resection and titanium mesh and bone graft andinternal fixation. Group B, cervical anterior corpectomy plus titanium mesh and bone graftfusion and internal fixation group of30cases). Patients were followed up for6to36months,According to the Japanese Orthopaedic Association JOA（Japanese OrthopaedicAssociation Scores）Score comparison and efficacy evaluation of the rate of improvementof the two sets of surgica. Results: Group A and Group B (The posterior longitudinalligament resection group and the posterior longitudinal ligament retention group) The twogroups were gender, age, severity, duration, days of hospitalization, surgical proceduretime, Preoperative JOA score were compared.Found no significant difference in the yearsafter the two procedures, the patient’s neurological function of spinal cord have beenrestored, a certain degree of improvement. More has a significant difference in the twogroups to improve the rate of surgical disease, Group A is the posterior longitudinalligament resection group of patients with postoperative JOA score and improvement ratethan in group B is retained group. Conclusion: In the same surgical indications as well as the same surgery scientific and accurate surgical operation on the basis of the removal ofthe posterior longitudinal ligament ossification hyperplasia longitudinal ligament can bebetter retained after adequate decompression, the lifting of spinal cord compressionsymptoms.improve neurological function improvement rate, long-term efficacy is betterthan the latter. At the same time, the incidence of complications was significantly lowerthan the latter.
