Incidence and risk factors for the misplacement of pedicle screws in scoliosis surgery assisted by O-arm navigation —analysis of a large series of one thousand, one hundred and forty five screws

ConclusionO-arm-assisted navigation does improve the accuracy and safety of pedicle screw placement in scoliosis surgery. However, unavoidable screw malpositioning remained, which occurred significantly more often in patients with CS and NF-1, in middle-thoracic spine, in the concave pedicles, and in the segments three levels away from the tracker.
