[Application of computer-assistant neuronavigation in spinal operation].

Objective: To discuss the efficacy, accuracy, and safety of computer-assistant neuronavigation in operation of vertebrae and spinal cord.
Methods: The data of computer-assistant neuronavigation used in the operation for 41 cases, including 9 cases of neurinoma, 10 cases of ependymoma, 5 cases of angioreticuloma, 7 cases of spinal meningioma, 4 cases of astrocytoma, and 1 case of cysticercosis, and 1 case of osteoblastoma. from March 2001 to December 2003 were reviewed.
Results: Twenty-six screws were fixed in 4 patients. Total removal was succeeded in 33 of the 37 cases of 37 spinal tumors and all patients survived after operation.
Conclusion: Image-guided navigation for spinal surgery is able to save time and reduce operational lesion. More importantly, it improves neurosurgeon's comprehension of spinal anatomy.
