简要总结
The goal of this study is to prospectively collect information about the operative time and intraoperative radiation experienced by patients undergoing posterior spinal fusion procedures guided by the MvIGS spine navigation system.
详细描述
This is a single-center, prospective case series to assess the use of the Machine-vision Image Guided Surgery (MvIGS) spine navigation system for treatment of spinal stenosis, scoliosis, and spondylolisthesis that requires fusion. This is a single-arm, open-label study. All participants will undergo their single and multi-level posterior spine fusion surgery using bilateral pedicle screw instrumentation under MvIGS intraoperative navigation guidance.
