The invention concerns a method for drilling a vertebral pedicle in particular for setting a pedicle screw using a motorised hand-operated instrument. The invention is characterised in that it consists in implanting prior to drilling an electric signal sensing electrode on a muscle and in connecting the drilling instrument to a voltage source, and in controlling a warning system in the event that the implanted electrode detects a signal correlated with the drilling instrument voltage source.
