Abstract:
Objective To evaluate the surgical technique of titanium miniplates in reconstruction of laminar roof after a posterior approach in intraspinal tumor surgery. Methods From August, 2007 to March, 2009, 11patients underwent intraspinal tumor surgery with osteotomy and reconstruction of laminar roof, titanium miniplates were used for fixing in the re-implantation. There were 2 intramedullary tumors,9 extramedullary tumors. The target of surgery was the cervical spine in 2 cases, the cervicothoracic spine in 4 cases, the thoracic spine in 2 cases, the thoracolumbar spine in 2 cases, and the lumbar spine in 1 cases. The patitens were followed up for 6 months to 2years. Local pain,bony healing and spinal malformation were assessed. Results In the 11 patients, there was no case of dural, nerve root, or spinal cord injury due to laminar roof reconstruction. One patient complained of moderate to severe local pain during follow-up and 2 patients complained of occasional slight pain at the surgical site. No limitation of activity occurred. Bony healing was confirmed radiologically or CT scan in 9 patients. There were no patients demonstrated a new spinal malalignment, and no patients developed stenosis of the spinal canal. Conclusions The reconstruction of the laminar roof using titanium miniplates will benefit the recovery of normal structure of spine,and maintain the stability of spine,and avoid the occurrence of stenosis of the spinal canal.
