Application of Splitting Vertebral Laminae and Reconstruction of Posterior Structures of Vertebral Canal with Titanium Web to Surgery for Thoracolumbar Vertebral Canal Lesions

Objective To explore the application of splitting vertebral laminae and reconstruction of posterior structures of vertebral canal with titanium web to surgery for thoracolumbar vertebral canal leions. Methods The surgery through posterior median approach was performed from January, 2004 to January, 2008 in 36 patients with thoracolumbar vertebral canal leions. The spinal processes and vertebral laminae and outer layer yellow ligament were retained and the posterior structures of the vertebral canals were reconstructed with titanium web after removal of the tumors. Results Of 36 patients, 18 were recovered well, 12 significantly improved in the symptoms and 6 were not improved 6 months after the operation. No patients died. The fusion of the vertebral lamina and spinal process was detected by CT 6 months after the operation in 10 patients. Conclusion The curative effect of splitting vertebral laminae and reconstruction of the posterior structures of vertebral canal on the patients with thoracolumbar vertebral canal leions is good.
