Accuracy of imaging grading in comparison to open laminectomy to evaluate pedicle screws positioning.

Study Design: Prospective experimental study.

Objective: To compare the accuracy of O-Arm-acquired radiographic and computed tomography (CT) evaluation of thoracic pedicle screw placement with open laminectomy in a simulation laboratory.

Summary Of Background Data: Improving surgical safety and procedural efficiency during thoracic posterior spine instrumentation is essential for decreasing complication rates and possible related risks.
