A system and method to detect fracture in a pedicle portion of a vertebra. The system includes a longitudinal member adapted for insertion into a pedicle and a sensor including first and second electrical contacts for connection to first and second portions of the longitudinal member. The longitudinal member includes a head portion having an opening extending axially within the longitudinal member. A conducting rod is positioned within the opening and is electrically coupled to the longitudinal member distal from the head portion. An insulating sleeve is interposed between the longitudinal member and the conducting rod, where the longitudinal member and the conducting rod form an electrically conductive path for connection to first and second contacts, respectively. The sensor is adapted to detect a breach in a pedicle based on a change in an electrical impulse signal between the first and second contacts.
