Does the interfacing angle between pedicle screws and support rods affect clinical outcomes after posterior thoracolumbar fusion? A retrospective clinical study

Instrumented posterior thoracolumbar fusion with pedicle screw systems is an established procedure for the surgical treatment of numerous degenerative spinal disorders, with increasing case numbers worldwide. [1] Although most patients benefit from the intervention, the cumulative revision rate after spinal fusion surgery is approximately 15% no later than 5 years after surgery [2 –5] and increases to well over 20% after 10 years. [5–9] For scoliosis correction, revision rates as high as 18% to 56% are reported 4 to 6 years postoperatively.
