In the first case, we performed removal of extradural spinal tumor of the sixth thoracic vertebra and O-arm-navigated pedicle screw fixation. In the second case, we performed O-arm-navigated corpectomy of the fifth cervical vertebra and anterior spinal reconstruction and fusion with titanium expandable mesh and cervical plate in connection with degenerative narrowing of the cervical spinal canal that lead to clinically manifested myelopathy.<\/jats:p>\n<jats:p>The initial experience allows us to conclude that O-arm-based image-guided spinal surgery can lead to considerably higher precision of spinal instrumented procedures.
