Traditional pedicle screw versus cortical bone trajectory in the upper thoracic spine: A technical description and retrospective comparative review

Patients who underwent CBT fixation had preserved cervical spine alignment at their final postoperative visit. The use of CBT led to a reduction in total length of OR and trended towards a lower complication rate. Given the early findings of our study and others it is likely that CBT screws in the upper thoracic spine will become much more common place at the end of both cervical-thoracic and thoraco-lumbar fusion constructs given their demonstrated benefits.
