ABSTRACT

Introduction: for the placement of transpedicular screws, the use of various techniques began, such as the use of conventional trans-surgical radiography and trans-surgical fluoroscopy. These methods imply greater exposure to radiation, greater surgical time and economic expense. Objective: to report the percentage of failed placement of transpedicular screws with the freehand technique and to describe the freehand technique for transpedicular screws. Material and methods: between March 2020 and March 2022, 40 patients (23 men and 17 women) underwent spinal surgery with transpedicular screw placement using the free-hands technique. In total, 236 screws were placed in the thoracic spine and lumbar spine. We divide the medial or lateral penetration of the pedicle into grade 0, grade 1, grade 2, grade 3 and grade 4. Result: according to the classification of transpedicular screw placement, 96.2% was grade 0, 1.2% grade 1, 2.1% grade 2, 0.4% grade 3 and 0% grade 4. Conclusion: the placement of transpedicular screws with the freehand technique is a safe technique to perform in the different pathologies of spinal surgery.
