Study Design:
A report of three cases of thoracolumbar vertebral collapse treated with image-guided anterior corpectomy.
Objectives:
To document the surgical technique and the usefulness of image-guided anterior corpectomy for thoracolumbar vertebral collapse.
Summary Of Background Data:
Computer-assisted navigation systems can provide accurate three-dimensional surgical information intraoperatively. However, there is no clinical report regarding the application and usefulness of the computer-assisted navigation system for anterior thoracolumbar corpectomy.
Methods:
After exposure of anterior and lateral aspects of the vertebral bodies through the transpleural approach, a reference frame was fixed to the thoracolumbar spinous process. Then thoracolumbar corpectomy and decompression were carried out under computer assistance.
Results:
The tip of the standard probe and the angled rongeur could be monitored on three-dimensional images during surgery, and the retropulsed fragments within the spinal canal could be safely and completely removed under computer assistance.
Conclusion:
This image-guided procedure would aid surgeons in the complete and safe decompression of thoracolumbar injury.
