Abstract
The present invention concerns a method and equipment for drilling bone, in particular for setting a pedicle screw using a manual or motorized drilling tool. The equipment includes a drilling instrument, a source of electric impulses and a connector for connecting the electric impulse source to the drilling instrument. The equipment includes at least one sensor for detecting a muscle signal either implanted in a muscle or placed on the skin in the vicinity of a muscle before and during drilling. An alert is produced in the event of detection by at least one sensor of a muscle signal correlated with the source of electric impulses connected to the drilling instrument.
