The modified cervical single open-door spinal canal enlargement combined with Y-type nano bone-plate internal fixation for cervical spondylotic myelopathy
Objective To investigate the effect of modified cervical single open-door spinal canal enlargement com-bined with Y-type nano bone-plate internal fixation for treatment of cervical spondylotic myelopathy.Methods The 35 patients with cervical spondylotic myelopathy were treated by modified cervical single open-door spinal canal en-largement combined with Y-type nano bone-plate internal fixation.The operative conditions and complications were re-corded,the cervical axial symptoms and spinal cord functional recovery were evaluated by JOA scores.Results The operative time was 70～135(95.6±16.5)min,and the blood loss volume was 100～250(180.5±22.4)ml.All pa-tients were followed up for 6～24(13.5±1.9)months.All incisions healed in one-stage.There were no nerve root,dural and spinal cord injuries or iatrogenic axial laminae rupture.There were no postoperative complications such as cerebrospinal fluid leakage,epidural hematoma formation,incision infection and cervical physiological inversion.Post-operative X-ray examination showed that the internal fixation position was good,and no loosening,plate fracture or screw fracture occurred.The spinal canal was enlarged significantly,the spinal cord was not re-compressed,and no re-closing occurred.Compared with the preperation,the JOA score was improved at postoperative 2 weeks and the last follow-up(P＜0.05).Conclusions Modified cervical single open-door vertebral canal enlargement combined with Y-type nano bone-plate internal fixation can avoid the re-closing phenomenon,reduce the incidence rate of axial symp-toms,with few complications,and better spinal cord function recovery.
