Keywords: Vertebra, spinal fractures, pedicle screws, fluoroscopy, accuracy

Objective: Pedicle screw instrumentation is gold standard for unstable traumatic thoracolumbar fractures. Techniques for pedicle screw placement are free-hand 2D fluoroscopy guidance and stereotactic navigation. Aim of this study is to evaluate the reliability of free-hand technique.

Materials and Methods: 450 polyaxial pedicle screws used by 62 patients were evaluated. All screws were placed with free-hand technique at an education hospital. Accuracy of the screws were graded with Zdichavsky grading system.

Results: 397 (88.21%) of 450 screws were graded as 1a (best position) and 1b (good position). Except 8 malpositioned ones positions of 442 (98%) by 450 screws positions were acceptable.

Conclusion: Regardless of the pedicle screw placement technique the skill and experience of the surgeon designates the success of the surgery. For unstable traumatic thoracolumbar fractures pedicle screw placement with free-hand is a reliable technique and avoids excessive radiation exposure both for surgeon and patient.
