Mean time to place lumbar pedicle screws with AR

According to a study carried out in China in 2019, it was found that augmented reality-guided lumber pedicle screw placements could be carried out quicker than a radiograph-guided method. The AR-guided operations had a mean time of under 132 seconds compared to 181 seconds for radiograph-guided operations.
