The xvision system has demonstrated a 99.1% overall percutaneous screw placement accuracy, eliminates the attention shift of referring to a separate screen and adds these features to potentially decreasing the radiation exposure demonstrated through traditional fluoroscopy-based procedures. An additional published study yielded non-inferiority results over published freehand studies*

The PIR is a combined value of all cognitive domains tested and scored from 0-100. The PIR can reflect a singular test date or represent the average performance over a custom interval chosen by the user.

PIR scores can be compared against past performance ratings, or against a specific population of performers. For example, an athletes performance can be compared against the performance of other athletes among the same position over time.
