<sec><title>OBJECTIVE:</title> To analyze the occurrence of poor positioning of pedicle screws inserted with the aid of intraoperative electromyographic stimulation in the treatment of Adolescent Idiopathic Scoliosis (AIS).</sec><sec><title>METHODS:</title> This is a prospective observational study including all patients undergoing surgical treatment for AIS, between March and December 2013 at a single institution. All procedures were monitored by electromyography of the inserted pedicle screws. The position of the screws was evaluated by assessment of postoperative CT and classified according to the specific AIS classification system.</sec><sec><title>RESULTS:</title> Sixteen patients were included in the study, totalizing 281 instrumented pedicles (17.5 per patient). No patient had any neurological deficit or complaint after surgery. In the axial plane, 195 screws were found in ideal position (69.4%) while in the sagittal plane, 226 screws were found in ideal position (80.4%). Considering both the axial and the sagittal planes, it was observed that 59.1% (166/281) of the screws did not violate any cortical wall.</sec><sec><title>CONCLUSION:</title> The use of pedicle screws proved to be a safe technique without causing neurological damage in AIS surgeries, even with the occurrence of poor positioning of some implants.</sec
