The PediGuard is a battery‑powered, single‑use tool for drilling pilot holes in spinal pedicles into which pedicle screws can be inserted during spinal surgery. Small comparative trials in different populations of adults and children show that the PediGuard can reduce exposure to fluoroscopy, has high sensitivity and specificity for detecting pedicle perforations, and can significantly reduce the number of malpositioned screws. The PediGuard costs £500 per unit compared with the standard pedicle awl, which costs about £300.
