Summary
Guide wire displacement during robot-assisted spinal surgery is rare but can cause complications. Avoiding this issue is crucial for improving screw accuracy and patient outcomes in pedicle screw implantation.
Area of Science:
- Neurosurgery
- Robotic Surgery
- Spinal Implantation
Background:
- Robot-assisted spinal pedicle screw implantation offers precision but carries risks.
- Guide wire displacement is a potential complication that can affect surgical accuracy.
Purpose of the Study:
- To analyze guide wire displacement during robot-assisted pedicle screw implantation.
- To identify strategies for reducing displacement and associated complications.
Main Methods:
- Retrospective study of 398 patients undergoing robot-assisted spinal pedicle screw implantation (April 2017 - December 2019).
- Analysis of causes for guide wire displacement in 60 identified punctures.
Main Results:
- A total of 2,408 pedicle wire punctures were analyzed.
- A guide wire displacement rate of 2.49% (60 out of 2,408 punctures) was observed.
- Associated complications included one case of thoracic segmental artery injury and one case of incomplete spinal cord injury.
Conclusions:
- Guide wire displacement is a rare but significant complication in robot-assisted spinal surgery.
- Minimizing guide wire displacement is essential for enhancing pedicle screw placement accuracy.
- Avoiding displacement can reduce the incidence of serious surgical complications.
