Abstract: Objective　 To study the effect of vertebral canal reconstruction with micro titanium plate after multi-cervical segments Intramedullary tumor resection. Methods The enbloc laminectomy was performed by Tomita method in the 24 cases with multi-cervical segments intramedullary tumor. Among them, 7 cases resected laminae were re-implantation with micro titanium plate fixation. The vertebral canal were reconstructed and spinal stabilities were kept. Results No vertebral canal stegnosis, kyphosis and spine unstability were found after laminal re-implantation and vertebral canal plasty. However, the kyphosis, respiratory disturbance, sphincter dysfunction, cerebral spinal fluid leakage associated with intraeranial infection and epidural hydrops were in 5,2,5,5 and 3 cases respectively without laminae re-implantation and vertebral canal plasty.Conclusion After Tomita enbloc laminectomy, micro titanium plate fixed laminae re-implantation has keeping postoperative spinal stability for treatment of the patients with multi-cervical segmental intramedullary tumor and it would reduce the occurrence of postoperative complication.
