Spinal Fusion Clinical Trial
— NoHARMOfficial title:
Occurrence of Pedicle Screw Malposition in Spine Arthrodesis Surgeries Performed With O-ARM-guided Navigation at a University Hospital: a Randomized Controlled Trial
Background: Throughout the history of spinal deformity there have been continuous advances in the surgical treatment. Although many techniques have been successfully developed despite the anatomy complex, screw placement still remains difficult with a significant risk of misplaced implants. The O-ARM guided Navigation is a scanner that allows imaging of screws intraoperatively and could be a tool to facilitate screw revision and reduce the occurrence of misplaced implants. Methods: This is a prospective and randomized clinical study that will be carried out at the University Hospital of the Federal University of Piaui, which provides exclusive assistance to patients of the Unified Health System (UHS), in northeastern Brazil.
