Letter to the editor regarding “Does the interfacing angle between pedicle screws and support rods affect clinical outcomes after posterior thoracolumbar fusion? A retrospective clinical study” by Noriega et al.

We read with great interest the article by Noriega et al. [1] investigating one of the causes of revision surgery. Revision surgeries or repetitious revisions are one of the biggest nightmares of spine surgeons and we must do our best to avoid revisions. The authors defined pedicle screw/rod interfacing angle mismatch as any deviation from 90 ˚ formed by the axes between the rod and the pedicle screw head. Mismatch found to be associated with a higher risk of revision surgery by causing increased mechanical stress on the construct.
