[EX Q]: Question: Does pedicle screw reinsertion using previous pilot hole and trajectory reduce fixation strength?
Answer: Despite a significant reduction in pedicle screw IT, there was no significant difference in pedicle screw POS with reinsertion. Therefore, when surgeons must completely remove a pedicle screw for tract inspection, reinsertion along the same trajectory may be performed without significantly compromising fixation strength.
