Introduction
Guide wire displacement in spinal pedicle screw implantation was analyzed in order to reduce or avoid the occurrence of this phenomenon and to reduce the complications associated with robot-assisted pedicle screw implantation surgery.

Material and methods
From April 2017 to December 2019, a retrospective study was conducted with 398 patients who underwent robot-assisted spinal pedicle screw implantation. The causes of guide wire displacement in 60 punctures were analyzed.

Results
There were 2,408 robot-assisted wire punctures of the pedicle, of which 2,348 wire punctures were located well within the pedicle, and 60 wire displacements occurred during robot-assisted wire puncture, with a displacement rate of 2.49%. There was one case of thoracic segmental artery injury and one case of spinal cord incomplete injury.

Conclusions
As it is a rare phenomenon in robot-assisted spinal pedicle screw implantation, guide wire displacement should be avoided as much as possible to improve the accuracy of screw placement and reduce surgical complications during the operation.
