Abstract:
Objective To discuss application of initiative infrared ray computer assisted 3D navigation system in spinal complex operation to improve surgical safety. Methods From December 2002 to July 2004, we performed 90 cases of spinal operation assisted by computer 3D navigation system. There were 38 cases of spinal fractures, and 236 cases of pedicle fixation. In lumbar spine surgery, fluoroscopy was commonly used, because the pedicle of lumbar spine was thick enough. 3D computer navigation was used in the other cases. Results 4 screws (1.7%) were not in good position, and the position error rate was 0.23 to 0.56 mm (automatically calculated by the computer). But we had once performed 272 cases of fixation with cervical pedicle screws just assisted by G arm or C arm fluoroscopy, 29 (10.7%) of which were not in good position. Conclusion In comparison, computer navigation assisted operation can make pedicle screw positioning more correct.
